Can we say DELICIOUS!!!!!!

[swheels]

Man i wish i would have came across this before i ordered another race head.LOL But at some point i'm gonna end up running this head before the race at V.I.R even if it means i have to get rid of one of my v2 heads.thumbsup2

Oh and checkout the Zongshen new motor too.Looks like they to went the way of the hybrids.LOL

I can only imagine what kind of hp you can get out of that head on a 1fiddy.I bet over 20hp.thumbsup2Now i'm thinking lifan really better step their game up.

[swheels]

I just did a little more probing and found out that these 4 valve heads will be coming from the yx factory(so this means it won't be costing and arm and a leg).Not only that but there's a bbk that takes it all the way up to a 180cc.So there will be a single cam 4v head that you can make from a 160cc all the way up to a 180cc.DAM that's sick!!!!!
Oh and i also found out it should be hitting the markets in a month.

I'm in line already!thumbsup2

[Blitz$M.Inc.$]

sweet, i just got a krp 150
man them motors rev up fast
im sure they will have a kit for the 150s too
how did the 110 project go?

[swheels]

how did the 110 project go?Oh shizzle Blitz on 1 fiddy too.I had to put ta on hold for a few.Somthing else has sparked my interest.Infact a dual spark setup.Iv'e seen some pretty sick dyno numbers from takegawa dyno sheet with there setup.So this at the time seems like an easier thing for me to attemp.LOL So i'm gonna practice that on the 110cc first.

But coming from the yx factory i'm pretty sure it's gonna be a kit for the 150's.The single cam 4v head plus the piston to match.So you can swap it right out on to your hybrib motor.thumbsup2

[X7rocks]

holy crap...... i think builds on the midbikes are gonna be crazier then ever for now on :)

[swheels]

holy crap...... i think builds on the midbikes are gonna be crazier then ever for now on :)Yeah and it shouldn't cost as much as buying the kitaco or the takegawa 4v head kit.LOLthumbsup2

[X7rocks]

i can imagine your name on the list for that engine already huh?

[Blitz$M.Inc.$]

looking at the head again, the thing im most happy about is the placement of the spark plug
its dead in the middle, you know how good a burn your gonna get? awesome
the bad side is the cam has 4 lobes? or 2 big ones?
ill reserve judgment on that till i see it, even takegawa has conceded that their dohc head is only slightly better than the best 2v head they have

[X7rocks]

damn straight looks like we have a real hemi engine now

[The Nutty Professor]

4 valve is why I held off from the V2 and money hahaha Right now the 4V may be only slightly better but give it time. I seem to remember when the 150's first came out two MBN members gave reason's why the YX was the way to go. Everyone was hot for the Lifan because it was faster out of the crate and the fact the YX would lunch it's clutch didn't help. Folks this is what we (Swheels and The Nutt) could see coming. We must have talked about it for hours. Are we Einstein? No we could see the bleed over from Takegawa and the YX. In due time someone else will trump YX but for now it's the king BABY!

[X7rocks]

now we just need more affordable rockers for the honda engines :) i prefere to stick with my 146 i like the power it gives and the nice smooth torgue it gives out

[swheels]

If your refering to the takegawa DOCH head.That i can believe because of more rotating parts and the weight of that setup.But on that note with this head we still should be able to use the takegawa S series cams for the flat tappet heads.thumbsup2
If the katico 143cc 4v kit can pull harder than a 172+R kit.Well it should be insane on a 150cc then.But i'll keep my finger's crossed.

[swheels]

now we just need more affordable rockers for the honda engines :) i prefere to stick with my 146 i like the power it gives and the nice smooth torgue it gives outYeah if that's whatcha like it's cool.But is very limited now.I was gonna put my 146 in the back up bike.Now i'm not so sure if it would be worth the money to build on.Knowing that theres more bolt on ready Hp parts out there for the yx/klx styled motors.

[X7rocks]

thats true...i just dont see that many yx motors in midbikes since they are a bit pricier then building a 125 engine

[swheels]

thats true...i just dont see that many yx motors in midbikes since they are a bit pricier then building a 125 engineA stock klx/yx 150 will beat a 125cc with a 146 bbk on it.You'd have to work that 146 to get more power out of it.Which translate into more money being spent.So either way your gonna have to spend money.I'd just rather spend the money knowing i'm gonna get a higher return.

[swheels]

I just checked my email and got a response from the company.


Their response:[4v head price for klx yx engine price $160.]

They also asked what business or company do i represent.LOL So i'm assuming that's the wholesale price not retail.So you figure retail it would cost double.So figure over $320. crazy thing is at the site it says takegawa.But the $320 i'm guessing that's what the yx 4v head might be priced out at.Don't quote me on this cause all i asked about is the head.When they come out i'm pretty sure it will be a kit that comes with a new piston to work with the 4v head.thumbsup2

[SoPackedCustoms]

Well how many pieces is considered whole sale to them me be we can all chip in and get them?

[james1300]

Well how many pieces is considered whole sale to them me be we can all chip in and get them?

Can we get complete engines with the 4 valve head installed?
'Plug and Play'!
What carb do you use with a 180cc 4 valve head?
Exhaust?

Sorry for all the questions, But Id Love to have another bike with a BIG BORE, and Stroked crank.

[X7rocks]

depends on the size of the intake valve if the valves are around 25mm for the intake then a 26 or a 28 would be for best performance without over carbing the engine

[Blitz$M.Inc.$]

in a 4 valve head the valves will be alot smaller
the kitaco 4v head uses 21.5 intake and 18.5 exhaust
but those are doubled so id get the biggest carb i could (28-30mm)

[swheels]

Well how many pieces is considered whole sale to them me be we can all chip in and get them?I'm on it.....I'm gonna put together a good business like email for them.Iv'e been thinking of including something along the lines of mentioning the midbikes and how they are like up and coming track bikes sorta a speak.To kinda give them an idea that there can be anew potential market for them to break into.Cuase they make pitbike,dirtbike,scooter parts and honda minibike parts.

what bore kit will work for my x1?

[Blitz$M.Inc.$]

um none i think, or at least not many

[swheels]

Doug's got those 180cc 4valve motor's in fresh off the boat,well airplane.thumbsup2 I spoke to him and he said he'sgonna throw up some pics.

Dam 180cc 4valve WTF!! the madness i tell ya.

[james1300]

Are they complete with Carb? What exhaust will I need for the X-18?:welcome:

[Blitz$M.Inc.$]

cool, i havent seen it on the other vendors sites yet

[swheels]

cool, i havent seen it on the other vendors sites yetDoug got the jump on all of them.These will be the first in the us.thumbsup2

[The Nutty Professor]

:stretcher: Hell I'm diggin deep with a two valve 150cc. With that I see some serious suspension mods that will HAVE to be done! I honestly think Swheels has the mods he needs to use the motor like it can be. The rest of us will be playing catch-up yet again bluelaugh I'm good with that it means I have work to do. Catching up to someone else is more fun than waiting for others to catch me. crazy_smilie

[Monster_Bike1780]

wow, a 2 valve 150cc motor. that its gunna be one bad motorbows_smilie

[The Nutty Professor]

thinking_smilie Dude they're all at least two valve? On a different note I rode a ZX-6R today it was a consignment bike the guy said "Just ride it I don't mind. If you crash I'm good just make sure you total it hahaha". I haven't ridden a 1:1 bike for sometime at that speed. I can see me in the head cheeses office tomorrow I rode in work clothes. Let's just say coming off a road we named "The Truman Parkway I scuffed my pant leg at the knee. Scared the crap out of me! No puck and I had it leaned that far without even thinking about it, STUPID!!!! I was working!!! If I had crashed and hurt myself I would be on the unemployment line I think :dunno:

Other than that I still say it's way easier to ride a 1:1 bike at least for me. No I'm not 1:100th the rider Nicky Hayden is but I got a little skill...until it comes to a MID moon1moon1

[doug@xmr]

These are crappy pics but best I could do.
Gonna take one apart on thursday to see what we can make betterthumbsup2

[Blitz$M.Inc.$]

wow, my legal bike needs that
how much are they gonna be?

[doug@xmr]

Gonna have to get back to ya.
The motors that I have right now are all spoken for but 2 and they'll be showing up on E-bay here pretty soon.

[shortguyonamotard]

cant wait for more details on these...looks like the OGM will be getting 4 valves!!! How much larger are these heads (worried about the 14" front wheel hitting when bottomed out)

[boogerboy722]

wow, my legal bike needs that
how much are they gonna be?

this was my first though. but i suppose i should get a motor to run it on first lol.

[Blitz$M.Inc.$]

ok so whats the deal with these heads?
from what i can find lurking around, they arent anything to write home about and the v2 roller head is still the best race option, also i heard of some reliability issues, seems that they need some bug time on these new china hybrid designs
even the takegawa dynos for their dohc motor only slightly beat out the +R head they also make, and ive heard talk of the yx 4valve being only a single cam is even weaker in comparison to the dohc 4valve motors of tak
does it need a 34mm carb to flow it?
i seen the dohc motors with a 28 get by
im starting to think for a high rev race motor the v2 is still the best, i usually find myself between 5k and redline while racing so i want the best in that situation

[The Nutty Professor]

I tend to agree about the 4V for now. I now have a V2, thanks "S", and I can see just by looking at it that it a major improvement over stock. I think I can bump that up too with a S35 cam and a high compression piston. That's about as hard and I want to hit on the 150cc. Yes I want to stick with the 150cc. There seems to be more classes running that motor than going bigger.

[swheels]

Well from what Doug was saying.When he took one for a test.Is that the power has a very linear curve to it and it really let's the motor rev high. Still very early though.But i think i'm gonna get one for when i setup the next bike.

[Blitz$M.Inc.$]

i just cant see how two Y shaped rockers are gonna spin faster than 2 single ones with rollers
if the 4 valve was roller id be listening more
but at least lets give them credit at trying to be innovative

[swheels]

I think good things are gonna come from the 4valves. Me personally i have grown to like more topend horsepower vs the lowend.I could relax more vs getting jerk around and running out of Hp at midrange. I ran the tak s35 cam and i absolutly love it.It fits me to a T. I swear if i'd had the proper gearing i would have stomped that 150r much sooner than later. So now i can only imagine that with some work done to the 4valve head, oh the possibilities. Cuz now my motor just pulls to the moon and keep reving till something lets go.LOL So i'm am really excited for the 4valve head and i may even get to use my FCR cab with it.This should be a good combo.thumbsup2

[The Nutty Professor]

No "S" I mean the 4V is the wave of the future, but right now somethings ot adding up right thinking_smilie They are not getting the power gains they should be? I think Blitz is right trying to run 4 valves off on cam is going to be a problem. I'm thinking about the 3V I have. People like the motor but for reason it didn't catch on? Maybe because the head only fit one motor :dunno: But even so you would think people would have bought a lot of them anyway but they didn't.

[Blitz$M.Inc.$]

somebody smart can explain why dual cams are better than one better than me but think of the drag on one cam that has not two but now 4 spring loads placed on it, there are some advantages im sure but its going to be very specific
if the Y rocker was a roller then id be more inclined, and does it run the regular cams? the ones ment for roller arms?

[The Nutty Professor]

You're right Blitz friction loss is a major factor and that also leads into heat build up because of it. Aprillia is getting away with it on one head of their V4 but they jumped through hoops and used gears and something else to minimize the friction.

Now use roller rockers in this head would lessen the problem but it wouldn't go away and they would probably make the head large enough that it would make sense to go DOHC anyway :dunno:

[X7rocks]

running a good synthetic oil may help a little bit...but im not sure it will completely help the friction on the cams. i know i wouldnt like a dry start on any of these 4 valve motors would lead to more cam ware then needed

[Blitz$M.Inc.$]

well ya i would hope everyone with a race motor would be running synthetic
if your not then i just dont know what to say
the 4valves are the future of hi performance for sure, the trickle down is in effect, just slow

[swheels]

well i spoke to Doug the other day. His words is...............The motor is a MONSTER!!!! He said you literally have to sit on the tank to keep from flipping backwards.speechless33 Of course you know they put their little fingers on the motor also.LOL He also said the rear suspension would definitly need to be re-done to deal with the power. Well i don'tknow about yall but this sounds like goodnews to me! Oh to many choices,i gotta get caught up on these projects.Soi can start the 2nd and 3rd trackbike build.banghead

[Blitz$M.Inc.$]

what is the holdup for these going on sale?
nobody yet has them

[swheels]

what is the holdup for these going on sale?
nobody yet has them I haven't a clue but i'm guessing the pitbike dealers (a majority of them) is still testing,modding and tuning them before they put them out for sell. And Doug has gotten his hands on the revised versions.thumbsup2 So it shouldn't be to long now.

Yeah i think imma bite the bullet and get one for the other bike.

[Niusiic[latvia]]

Now that's one big engine! And how much HP?

[The Nutty Professor]

There was one for sale on Ebay a couple weeks ago.

im starting to think for a high rev race motor the v2 is still the best, i usually find myself between 5k and redline while racing so i want the best in that situationNow you can right home about them.LOL I spoke to Luise@xmr a few minutes ago.To hear him say" so far this is the fastest motor they've been on including their bikes". I' even more impressed and i immediatly scrapped the plans i had for my current motor and my 146cc motor.LOL He said he road the bike and it was un-rideable, you do have to sit on the tank.He took it for a very short ride then got off quickly he said. To hear this coming from Luise with his Derbi powered x12 2 stroke 70cc bike.Now i'm really like DAM!

i just cant see how two Y shaped rockers are gonna spin faster than 2 single ones with rollers
if the 4 valve was roller id be listening more
but at least lets give them credit at trying to be innovativeLuise told me that in his opinion it looks like they did their homework on the cam drag theory.They have HUGE cam sprocket which suggest that they did the ratio( sorta like a gear reduction) to help eliminate the drag.Plus instead of 2 springs like the 2valve heads they used one heavy duty spring per valve.Plus with the smaller lighter valves,Valve float shouldn't be an issue. Luise also mention that the motor they did is running a 30mm carb and inner rotor kit.The motor spools up so fast that you'd think at half throttle it's at the top of the rpm range.He also mentioned that they got 2500 more rpms with the 4valve head.speechless33:yup: Oh plus it has a real big beefy cam chain likes the crf 150r's:yup:

somebody smart can explain why dual cams are better than one better than me but think of the drag on one cam that has not two but now 4 spring loads placed on it, there are some advantages im sure but its going to be very specific
if the Y rocker was a roller then id be more inclined, and does it run the regular cams? the ones ment for roller arms?I Read that you can time the cams on the duallies individually for better performance.

;43081']Now that's one big engine! And how much HP?Iv'e 3rd hand info from Luise in which he has read and from what he read about the 4valve heads.They weren't specific on were the hp numbers were at the base of the motor or to the rearwheel.So i won't spit the numbers out but i'll say this.Let's just say 30hp is not far from the horizon now.With the proper work i might add,not just slapping on the head and go.But it will be easier than any of the stuff running now. So don't hold this as law though! Still i'm definitly taking the plung.


I have founda home for my FCR CARB!!!!!!

[RomanianRacer]

ok so how much are these motors again? And is there like a spec sheet I could take a look at?

I might have to change my plans of running a custom 125 2t in my x12. I hope it's under a grand, if not then I'm sticking with the 125 2t.

I'll ask them how deos this motor compare to their 2 stroke 125cc drag bike and their 80cc 2stroke x12. But they did say the fastest they've been on thus far.


I hope you read what i posted up.Cuz i did say they put their hands on the motor that they put into the bike.

[swheels]

Finally some more test results on the 4valve head.thumbsup2

This testimonial was taken off of planetminis
Re: tb 160 v2vs yx 4 valve?

--------------------------------------------------------------------------------

well i have ridden both and they both rip , they run just like you would think and the YX 4v sings on top
also we only started offering it after info and experience gained last summer / fall from racers
the YX 4v is Very close to a Kitaco 4v just like the Tb V2 is similar to a Takagawa +R
we have them both in stock every day

just one note the 4v yx head fits klx110 but its a honda port head , we have good forward intakes and stainless klx pipes with honda head bend in stock too

--------------------------------------------------------------------------------
so the yx makes more power than the v2?

do all yx's sing? i have a 2 valve on my bike rite now and it does it and its annoying.


yea sorry for the old school terminology "sings" meant it pulls hard or runs strong in a particular RPM range , so when i say it sings on top , that means it has a very strong pull in the upper RPM ranges.
So i can only imagine the performance gains when they start producing different cams for this head also.

[The Nutty Professor]

Call me cautious but I want to hear a customers opinion not a dealer. What would be perfect is to hear something from Kurlon or one of his buddies.

[swheels]

Either way i have plans to run a 4valve motor for next years bike either way.So it's a done deal for me.thumbsup2 Once i get something in my head and i'm fixed on it.I will not change my mind no matter the outcome.:yup:

Just having trouble trying to decicde if a want monster motor.Or to remain under the usmgp rule limit to 165cc. I'd hate to play fair only to be out powered AND out ridden.bluelaugh I can deal with one or the other but not both.

[Blitz$M.Inc.$]

i just reread your part about luigis input S
i agree that the cam sprocket needed to be bigger to handle the load, and if you look at it, its still only pushing 4 springs, the same the regular heads have, so the drag i was worried about, seems to be addressesd
i expect the roller head to be very quick through its rpm, and the 4 valve will be the high rpm king
also i think i saw kurlon say this, the 2 valve head piston has a very steep 'roof' which is what is the force that drives the piston down with
with the size of the valves approaching the insane limit, that 'roof ' looks my old one in buffalo, which will limit the impact of the added other things
if you look on the 4valve heads, the valve cutaways are very small and leave a very 'flat roof' for the mix to pop off, having a 'flat roof' will absorb alot of the usable power

That was my favorite vid demo of the 4valve. Now just that was with an outer rotor on that motor. Imagine what it would rev like with a inner rotor kit on it.speechless33 Next years racing is going to be FUN!
Them dam rear tires are gonna have fits.I hope by then slicks will be more availible.Becuase i'm thinking everybody's gonna be burnin the crap out of their tires fighting for traction.

I am beginning to question my use of IRKs on our engines. On every one of ours that has an IRK, we have had clutch issues (grenaded clutches). now granted, we are VERY HARD on clutches, so it may be that.

But I got to wonder if the IRK speeds the damage up that we are sure to have anyway.thinking_smilie

I still love the inner rotor kit though.Since this motor seem to spool up rather quickly with the outer rotor.I will try it with one,i do know i will be putting an inner rotor on it the motor eventually. Well when i get the motor should be the first of Jan or the end of Jan.LOL i'll have the motor before the bike is finished.banghead

Idk, about those 4 valve motors. I heard talk from Firepower Minis, that he won't carry them for a while cause he took a look at them and noticed the valves looked pretty close to the stock head. There is a whole debate about the V2 race head and 4valve head at planetminis.

Which someone had posted up a good point.It seems like theres a vendor war going on over there.So it seems that once one vendor gets the jump on another with a potential hot product.Then the vendor that seems to be behind has to try and dis-credit it in some kind of way. Now the selling point for me was that some good friends gave me first hand review.thumbsup2 Besides firepower has not tested one sooooo on that note.What does it sound like to you??????? Man these guys are gonna have you kids brain washed before you know it. If he's not man enough to run one then should everybody follow. Not i said he who thinks outside the box. Hell i'm still waiting to blow up my yx motor.Which i could remember a bunch of people saying they won't last.LOLOLOL
Remember if your gonna tell someone elses story tell the whole thing.thumbsup2 Now on the bench and in a bike testing is to totally different veiws. Trust me Firepower knows what's going on that's why he has them.So he don't get left behind in the vendor war.You gotta read between the lines when it comes to vendor's posting over there. LOLOLOLOLOL

[rene13]

Hey "S" point me in the right direction, who has them and how much?:yup:

[RomanianRacer]

T-Bolt USA and Ahp Minis carries the YX 4 Valve Head. You gonna get the 184cc bbk, rene?

[briansX19haulsass]

184cc 4 valve

[rene13]

I want to get one of them but my concern is clearence between the top of the head and tire during heavy braking.thinking_smilie

[briansX19haulsass]

I bet they will be fine..... Someones gotta test it out first though....

Rene you have a yx 150 or 160cc?????

[Blitz$M.Inc.$]

rene, i had a similar stroked motor on there and even with my big maxxis front tire, it wouldnt hit the head, if your forks are that soft then you got some work to do

[swheels]

I don't think this was a 4valve motor. A member on PM had mentioned about a 172cc (horizontal) putting out 26.2hp dynoed.DAMN!!!!!! Imagine racing your mid with a motor (horizontal) putting out that kind of power. I might have to pay this guy to build me a motor.speechless33 Don't think i'll win a race but it would probably be more fun than a roller coaster.bluelaugh

[briansX19haulsass]

So its power your looking for huh. 220cc Billet motor sopposed 30-32HP and the rear wheel. Could you even imagine.... http://planetminis.com/f21/italian-220cc-billet-monster-engine-132780.html

Could you even imagine.... http://planetminis.com/f21/italian-220cc-billet-monster-engine-132780.html Yeah i seen and followed that thread. Nah if i was looking for some serious hp I'd shoe horn in a 250cc 2 smoker.bluelaugh It's a nice motor but for the price.I would definitly pass.Especially if you got guys getting 26hp out of a 172cc. To me that's just simply insane 26.2hp out of a 172cc 4 stroke horizontal honda clone motor.speechless33

The way i like to burn up the rear tire.I wouldn't get one weekend out of a set pushing 26.2hp.LOL

[briansX19haulsass]

How much HP you think you got right now S 17-18 maybe 19???? JW

[swheels]

How much HP you think you got right now S 17-18 maybe 19???? JWAfter hearing what my friend's motor was pushing after he had it tested on a dyno.His motor is a 184cc with the stock head and stock 26mm carb. His motor peaked out at 12hp to the rearwheel.I thought it would be making atleast 13 or 14hp to the rearwheel. So i'm guess if i'm lucky i might be at 14 or 15hp to the rearwheel. I'm not so sure of these Hp numbers now. Heck i could probably be at 12 to the rearwheel.I wouldn't be surprised.thumb_down

[briansX19haulsass]

what the hell..... S you got to be doing more then 12 man... Maybe a untuned 184cc with 26mm carb but man I thought it had more then that.... Vince said he just tested a 146cc motor with BVH and tb300 cam on it and made 15.4 HP at the rear wheel. How is that possiable when yours is 12..... I dont get it.

[swheels]

Vince said he just tested a 146cc motor with BVH and tb300 cam on it and made 15.4 HP at the rear wheel. How is that possiable when yours is 12..... I dont get it.I didn't get it either when my friend told me the news what his motor did on the dyno.LOL Broke my heart...LOL...Nah i know i'm more than 12hp at the rearwheel. I should be at 15hp to the rearwheel.But unless i put it on a dyno to see it. I can't spit out numbers as fact only speculation.
If a yx150 stock is suppose to be 11hp @ the rearwheel.With my setup i should be good for 3 to 4 more hp gains easily.:dunno: The only thing a can say is.The bike is very fast.I could probably get more out of the motor if i try a few things.It seems to be running great so i'm gonna leave it alone.thumbsup2

[Blitz$M.Inc.$]

i would have bet money that my 146 with the racehead made 15+
184cc at 12? thats retarded, i have a dyno of a stock 110 making 6hp

[briansX19haulsass]

haha thats what I thought too Blitz. I bet you wehn my motor is done at the machine shop it will be close to 16-17... That 184cc doing 12 though hahaaa somethings gotta be wrong there.......

[Blitz$M.Inc.$]

i have a place that will do mine right now, i just dont really want to spend the money with the stock 125 head on there, its nice on the low rpm but at high end it runs out of butt
i hate to be the guy thats always like 'soon i will do this' bla bla bla
thats why i never went into the turbo much or the dyno, it will happen when i post the print out and it will surly be impressive, or disappointing, either way its good nation knowledge
that 184 must have had the worst tune on it possible, a crappy carb, restrictive exhaust, a stupid dyno operator? idk
anybody know if gearing will play a role in the dyno?
like for racing i like 14/28, but for the street i like 17/28 bc of the higher topend
which should i dnyo on for the best numbers? 14/28?

[swheels]

I was going by feel fellas. Also i did mention his carb was a stock 26mm.On the dyno it showed that the carb was to lean.The sad part is his bike ran perfect and i do mean perfect all weekend.even lookin at the spark plug it didn't show it was running lean.He told me why it didn't register a lean reading on the sparkplug but i forgot what he said.
I'm pretty sure i'm making some decent hp cause my gearing was high and my motor only makes topend hp.Though when i got passed my friend a blasted by him.LOL So this has seriously got my thinking about saving for a Dyno. Either move to Va or stay in Nc and purchase a dyno plus forget about building another street rod.thinking_smilie LOL

[Blitz$M.Inc.$]

or just get one of those 143 dohc takegawa motors, you can get a close ratio 6sp and they make like 17-18 hp which is competitive plus they rev to the moon
http://www.hondaminitrail.com/GIFS/P825-DYNO-CHARTS-15-25-35.jpg heres a dyno with the superhead, 19 hp at 11.5k
speechless33 :yup: bows_smilie

[swheels]

This might change the game a little.bluelaugh
A 160cc 4valve liquid cooled. Loins,tigers and bears oh my.bluelaugh

Yep the same dyno that was refered to for the 138cc.Unless they were just advertising for the cams.LOL I will have to thoroughly investigate. I pulled this dyno pic atleast over a year ago. Somewhere on one these sites i was talking about the dyno # for the 138 using the s35 cam.That's what made me want the hybrid motor even more before they came out.

[Blitz$M.Inc.$]

18hp at 10k for all 3 cams, lol

[swheels]

18hp at 10k for all 3 cams, lol

Yeah this was the graph that honda minitrails was using back then.LOL

[swheels]

Ok will i be cheating if i bolt one these in bluelaugh a gm lay down race motor from the dirt tracking race bikes. It's a single cyl horiz 500cc 4 stroker no trans just gas and brakes. I bet i'll get in and out corners so fast.bluelaughbluelaugh Oh also 4valves

[Blitz$M.Inc.$]

ya you can do that
when your slid out in a corner ill try to give you a wave as i pass bluelaugh
no really, there is gonna be a limit, somewhere, and i would think that motor would exceed a few, like length, torque

[X7rocks]

but ladies love the length and torque :D


on a serious note did not even know they made motors like that
FIRST POST OF THE YEAR!

[FiveStarSky]

oh yeah oval dirt racing is really cool to watch, talk about backing a bike into a turn lol, the motors are like that to keep the center of gravity low on the bikes so they can slide them through the turns

[swheels]

ya you can do that
when your slid out in a corner ill try to give you a wave as i pass bluelaugh
no really, there is gonna be a limit, somewhere, and i would think that motor would exceed a few, like length, torque You'd have to build the bike around the motor. More than likely would make a real good drag bike motor in one these mids.Twist the throttle and GOOOOOOOO!!!!!!!!!!!!!!!!!

[Blitz$M.Inc.$]

no actually without a tranny, it wouldnt be that hot on the drag strip, youd hit the redline and just tach out the rest of the way
it would be a better track bike motor, like a open class 50cc is in a pb
and you would have to build the bike around the motor like you said, its right side drive so a custom swinger to start, maybe the one you posted earlier

[swheels]

how much? That motor in the pics was 2k

what id like Yeah me likey too. I emailed them about a month ago never heard back from then yet.I emailed them about the efi system. I suspect it won't be much longer before they are readily available for a decent price. Then the name of the game would be who can get theirs tuned better to get the most out of the system.
I wante to have and efi 4valve motor ready for the new bike by mid summer. My fingers are still crossed.

LOL pretty soon everyone racing mids are gonna have to have laptops also to dial their bikes in for the desired track.LOL

It's like a double edge sword.LOL If you beat them, oh sure you beat a little kid.LOL Then you can't rough them up cuz you don't wanna make them crash and get hurt.

Palmer while sitting on his bike weighs less than my bike alone. But i'll be ready in march. I'm gonna change my gearing,yep i said the G word!

[RomanianRacer]

turbos seem like a PITA to get going right. All these variables to deal with! Plus the plumbing takes up a lot of space on the bike.

[swheels]

Ready to go and get the 4valve motor.But i'm nowhere close to even starting the other bike.LOL So the motor will just be sitting and waiting and waiting and waiting.bluelaughbluelaugh
Oh Blitz they got back to me about that fuel injection. $400.00 to $600.00 for the setup and they said their tryinh to keep closer to the $400.00 side. Now i don't know if that price is wholesale or retail.Oh plus they said they are trying to have their own ecu developed instead of the mega squirt.So that's the hold up on them as of now. Also they have 28mm throttle body and a 32mm trottle body setup.rock2

that is sound freaking beast just in words, it will be even more beasty in performance

[Blitz$M.Inc.$]

ya i guess thats what i would expect the efi to be, not too bad
might as well get the 32mm, all the heads are at 30mm
where did you find a whole 4v, ive only seen the kits so far, id like to be on that bus too
rracer, it would be hard for sure, but thats what custom is all about

[swheels]

Well i got my 180cc 4valve motor last weekend.rock2 and so far my plan is to let it sit in the box.crazy_smilie Till i decide what i'm gonna put it in. My bike as it sits right now will stay the same with the same 165cc in it. Don't think i'll be building another mid just to sit around in the garage. Cuz i'm thinking of going motarded.So i can race in the series that's closer to me.(2hrs Away)thinking_smilie

Since Blitz my bro your making the trek down to Ga to race.When ever you decide to go to sandyhook i'll make the trek up there to make a race.thumbsup2

[Blitz$M.Inc.$]

ya i guess my 160 will be sitting in a bike at least but it wont be raced until my personal evaluation
was kinda waiting on your review S before i get the roller or the 4V, 184 of course
this is the motor that will get the turbo, i found a custom shop near me that was the one that ran the dyno for my friend in his z50/110 bike
i need them to make the proper plumbing and cut and welding i cant do
they said they are stoked to try, they mess with boosted wrx's all day so this should be no prob

[X7rocks]

i was wondering what would a mid with the motor from my scooter be able to do....with the right parts they make 20hp and thats 20 hp from a dead stop till topspeed and they can hit 100mph.....:D sounds like a freak of nature though and all in 70cc!

[Blitz$M.Inc.$]

ask luigi, he knows

Also sounds like 184cc with a v2 race head and a good carb.That's been dynoed at the rear wheel too.thumbsup2

polini has made a new 90cc big bore kit that produces 34 hp wtf?!

[swheels]

polini has made a new 90cc big bore kit that produces 34 hp wtf?!LOL but polini ain't cheap neither.Polini also makes a 4 valve head setup for these motors too.LOL$$$$$$$$$

Now you need to put that kit on your scooter and go to the tracks to race.Then you'll see what it will really do........

[X7rocks]

S as much as i would love to that bigger bore/stroker doesnt come with its specific race pipe ><

the pipes on this bad boy is really different instead of it haveing the normal 2 bolt stud it has 3 of them and im quessing the expansion chamber is huge!

fun part is it is a watercooled motor so that would be a reliable powersource for the scooter,not sure for everyday though :(

but ill try to make it to sandyhook just need better suspension for the scooter. and maybe a bigger carburator and better cylinder kit.

[X7rocks]

here you go S i know your into the YX motors but i thought you would like some eye candy anyways

but ill try to make it to sandyhook just need better suspension for the scooter. and maybe a bigger carburator and better cylinder kit.Sounds like a lot of $$$$$$$$$.Plus it's still a race 2stroke setup which means rebuilds often. I like 2stroke it's just that now the power of the 4t's seems to be simple and at a lower cost to get you what you need.Especially when it comes to just bolting up a motor into the mids.No welding or fabricating needed.thumbsup2

here you go S i know your into the YX motors but i thought you would like some eye candy anyways I like motors in general and was pullin for lifan to come out on top.I still have hope for them it's just that the yx or the klx/honda motors have a ton more upgrades.That alone to me is well worth it.Options I'm still hoping lifan have something up their sleeves.:dunno:
Oh i see your watercool kit and i raise you.
You know i'm strictly about racing so if it's not on the track then.:dunno:
Besides hp doesn't always translate into a win at the track.

[Blitz$M.Inc.$]

looks like the takegawa head for the 50 builds but the cylinder is a polini?
wait till you see the new 5 valve designs- sike-
i want the 4V with a dual cam

[X7rocks]

vary true S i do like the sound of a good two stroke and 4 stroke

welll...idk if i should continue to make a race/street zuma with a watercooled motor im still thinking about it but cant come up with a final decision.

[RomanianRacer]

Imagine how much rep these little bikes would get if they were featured on the speed channel or were on the cover of a bike mag. I'm not saying stock though, like swheel's bike gets featured on them. I think a few people would drop the motards and swing by here and pickup a mid. The only thing is no one wants to pick up a stock mid, cause they SUCK!!!

ive had harleys hate on me mostly, some will try to power away from me only to find that im right behind them
some harley riders will give me the bike wave and thats cool, they reconize a motor bike at least
sportbike guys will break their necks to see wtf just went past them at 60
ive NEVER heard or seen anyone ever get props for a scooter or ped, our inside joke is to call them gay-peds
but a mid is a sexy mini sportbike, hard to diss on that, especially when they are fast as traffic
ive never seen a scooter that wasnt a hinderance in the street
if hes in your lane your like %^@^ when can i get over

honestly you must deal with some really crappy and slow scoots....specially if there that slow..my zuma sounds more like a dirtbike just with one gear and does right about now 62 mph with the small list of mods ive done

and as far as the polini big bore goes either the 70cc evolution (400 dollars) gets around 4,000 miles before a rebuild and still gets 21hp.

[Blitz$M.Inc.$]

there isnt many zumas here cuz of the redicious price
so the ones i see are the 49cc slow-peds
400 bux for a part that may last a year is some b_s
and for what? to look cool on a zuma?
you coulda had a mid better than mine with all the money you spent on that zuma

[X7rocks]

honestly blitz it just seems like you have your mind set on the midbikes only...

i take to consideration how i might get hit on the road with a midbike (cause here in waldorf not alote of people know how to drive) and as far as the rebuild goes since the walls are nikasil plated there is no cylinder replacement only ring and if needed the piston thats only a 50 dollar change.

"you could have had a mid better then mine with all the money you spent on the zuma" well...thats the part that sucks about growing up with my father....i needed a way to get around and hes not funding like alote of other kids around me. so i found the zuma at a good price and took it,and since it wasnt doing so well in traffic i upped it up. i have my eyes set on anything on two wheels.not just mids. and surprisingly your the only person that has given me such bad rep about it blitz =/ id thought as a fellow motorist you wouldnt rag on the scoots like that.

and gopeds are california brands scooters no lights or anything,in the state of maryland my scooter is considered a MC now due to the engine size...

[swheels]

I think i'm gonna bring the new motor with me to the up coming race.I think i'm gonna open her up and take a peek inside.If i open her up i will take some pics.Plus i might just do a little port work to the head.thumbsup2

Well i had my 180cc 4valve motor for a while now.(months lol)Just sitting in the box till i can figure out what i want to do with it.thinking_smilie
Doug@xmr and Luise@xmr said even in stock form this motor is truly a BEAST! Doug said it's also a sonuva B to get started because of the compression.Bent and broke kick starters had already happened to them.They also said jump starting them is not an option.The motor just locks up the back wheel even in 4th gear.
If i remember correctly Doug said the number for hp were 15hp to the rear wheel in stock form( i do believe this was with a 26mm carb on it).But this came from the company sooo.:dunno: The bore and stroke is 63x58=180cc Definitly a high torque monster.Plus this would explain why the compression is so high as compared to the 57 strokers.
I think if i do use this motor of course I'll be building a bike around it for it,just don't know what.:dunno: Fuel injection feeding this beast was one of my other goals.Well i was all for it,just can't see myself dumping more money into a build that will spend more time up on bike stands than on a track or in a lot riding. I can't build a shelf queen never been my style.

is that a bored out motor ora stock 180cc motor?

[swheels]

is that a bored out motor ora stock 180cc motor?They are all based off of the smaller blocks.Just some mild changes to the engine block.But yes it's a bored out and stroker motor still considred stock 180 though. I could take it up to a little over 200cc fairly easy too. Probably won't be good for nothing but a tractor pulling contest.

[Blitz$M.Inc.$]

no that would be sweet on the highway in my 18 thumbsup2
surprised they didnt run a 28 carb with it

[boogerboy722]

gogo 30mm carb, btw, what brand/model is that?

[shaq93]

how do those 4 valve heads compare top the v2's? i heard the v2's kill the 4 valve heads

[swheels]

how do those 4 valve heads compare top the v2's? i heard the v2's kill the 4 valve headswell i have both so i'm good.thumbsup2bluelaugh

You obviously haven't done enough research Soooo i'll let you do some more then you'll find your answer.thumbsup2thumbsup2

[shaq93]

a, help a brotha out please, can you give me an answer?

[TRT]

The 2 valves have better port configurations and WTF with all you moped haters?

Gay Peds you say...... coming from a mid bike rider is really funnybluelaugh
I beg to differ with you guys but you struck a nerve with me.....wave_finger

I have several mopeds, mid bikes and full sized bikes and I put more ride time on the mopeds. Everyone wants to buy mine... every time I go down town Detroit.... But my shit pulls wheelies and clocks 65-70mph quickly.....On a track a 2 stroke moped setup would smoke a 4 stroke honda based engine or even the hybrid shit.... these minerallli e2T engines can make 18hp easily and up to 24 with cranks and 50mm cylinder kits turning 16,500 rpms.....

lol chill out, that 4 valve motor would tear a regular 2v motor up with ease, and that motor isnt even bbk'd yet, that stock making about 15hp, thats not with a valve, piston, crank, or exhaust

[swheels]

a, help a brotha out please, can you give me an answer?When i get minds up and running in the new trackbike.I'll be sure and post vids from the races on the track. I'm not gonna go back and forth on the he say she say line.

Is that why alot of the big manufactures have more than 2 valves in their engines??????

Chillax there buddy i just call them as i see them about the scooters where i live.Plus my midbike stays on a track,parking lot or in the garage waiting till the next track day.When i first got it a took a few spins up and down the street. I got bored with that real quick.thumb_down
I've beat'in bikes on the track that had over 22hp to the rear wheels.So i don't think 18hp will be much concern to me.I'm not the type to rely on just hp when i race. Also (fact) the one time i did get to face off on the track against one those so called suped up scooters.It was a no contest period! I went right around it on a shitty running HYBRID MOTOR a worn out tt91 front tire and a rear slick that was so worn out,i had to throw it in the trash.Hmmm i think i still got pics of that tire.The guy that had the built scooter was really cool.He us all the things he did to it.Had the polini 72cc bigbore kit,the exhaust was done up and few others.He kept rambling on about it and yes it would pull wheelies too.
Hey if your scooter's that fast take it to the track and race it that's what i'd do.Well when the USMGP comes up this year.Maybe you can bring that scooter and race it with us.thumbsup2 This is why i like racing,cuz all the shit talking ends right there!
Getting over 20hp to the rearwheel on these hybrid motors is only a few bolt on parts away.
Oh FYI i don't care what type of machine it is.If it's supposed to be fast and it's not used to it's full potential like on a track.Then it's totally worthless to me!

just talked to the guys at xmr. they say that this motor has plenty of torque, the only thing is that he told me that he hasnt ran it in a x bike, just a metrakit. he also said that the motor might be too long for the x bikes and rub the front tire. Another thing is that they havent run the tak 178 scut kit or the tb184 bbk so they dont know how the power compares to it but there is a 194 bbk for this 180cc monster :yup: oh shoot, i forgot to say that there are no aftermarket parts for it; no cams, no of that stuff but there should be stuff coming out soon. S, this motor probably wont have much more power than your motor but then again it is stock so you can always build it up

My motor is a decent built 165cc of course this motor isn't gonna out power minds on top.When i drop it in a bike or what ever i do, it will most definitly be making more power than my motor.Otherwise it would defeat the purpose of me buying it. Theres a difference when your talking stock big blocks vs mod big blocks. I can blow pass a stock 150cc like it's a 110cc motor.But that doesn't say much.Hell i blew pass a basic 184cc on my 165cc motor like it was standing still.LOL Your not telling me something i didn't already know. Usually a big difference stock vs mod motors.thumbsup2
Besides i'm looking at the potential of the motor and i see somethings.
Just like i said about the klx hybrid motors before they came out.

[shaq93]

I also talked to vince about the 4 valve heads; he told me that these heads are supposed to make more power up top & that the v2's are supposed to make more mid range power. The thing is though is that you have no cam options for the 4 valve and you can always put a s35 cam in a v2 and have more up top power

Well here's what i'm gonna tell ya.I've seen dyno charts that somebody did on a forum using the 4valve head.He pulled 15hp out of a stock 172cc 4valve with the stock cam.He said he could have got more.But that's what he aimed for.thumbsup2 Like i said i see potential and when i'm ready.I will get the job done.:yup: Also there is another aftermarket roller rocker 4valve head out too. It won't be long now........:yup: Besides the yx 4valves are relatively new so of course they don't have aftermarket cams(that most people don't know of) Just like my V2 head,they are just now getting and aftermarket cam.Yes you can use takegawa cams in the V2.But those are not designated V2 head cams.Get it. So on that note theres a cam out there for the yx 4valve.Nobody has tried hard enough to find it.Me i have an idea and i'm willing to try it. Just like i figured out a way to convert the stock yx 2valve to a roller head.thumbsup2

[shaq93]

yea that 180 4 valve motor is crazy but for the same price you could get a built up 184 motor from ahp or tbolt. You would still have more room to build up also with that 180 though. I couldn't say what I would get if I had the choice right now

I couldn't say what I would get if I had the choice right now I like to build up my own motors for the most part.So when and if it goes POP!I'm not on the phone complaining about it just to hear,sorry no warranty on race motors.
That 184 would be a 186.59 and a 67mm would be a 204.51cc on on my 180 block.Plus because of the longer stroke this will put the piston closer to the top for more compression than the 160 block.So you know what that means. I've said enough now.LOL

[shaq93]

that's one thing about you s, you know your stuff

[swheels]

Naw man i had to learn just like everybody else and sometimes think outside of the box.Plus plenty of research when i'm interested in something.thumbsup2
If i would have listen to everybody or most people about the hybrid motors.I'd wouldn't have my 165cc motor now. Sometimes you gotta draw your own conclusions.

[The Nutty Professor]

"S" is right everyone was trashing the YX motors there for a while. We both realized that the Pit Bike crowd was putting those motor through more hammering than we would. He also searched outside the U.S. for information like I did. They had been used for 6 months to a year in Europe and Australia. Hell they already have billet blocks for what we use now. Just take for example the basic 150cc YX motor. There are a lot of little secret refinements that can be done to it to produce more power. As you go bigger those refinement will transfer into your new BBK if you plan it right. I use BBK loosely everyone seems to think it's the answer to their quest for speed. It's not. Getting the little stuff right is. Which is what "S" has done and continues to do. I am with him on this one. I refuse to go up in displacement until I get what I have running right. I will trash my 150cc until it screams for mercy or I break...which ever comes first.

[Blitz$M.Inc.$]

thats why i waited for the second revision of the yx with the bigger bearing support, plus i wanted to keep the same stroke as the 146
and if/when i do the turbo, i think the klx head has the most potential to flow and perform
