i have a 140cc krp engine i was just wondering if anyone has my engine or had any experinces with it. i can not get this engine to run right and about a year ago i just quit trying so if anyone could help that would be helpfull

so what is it doing?
there isnt that many variables to these bikes, surely you could have found the problem in a year

Sup b-brah good see ya back! Still having problems with the 140 huh? Damn! Guys if I remember right he's used 2 different carbs but both are Molkt which are junk. Yes I sent him one but I was hoping it would work. I still think his prob is carb related dunno though. The stock carbs they first sent out were pure shizzle.

ooooo ok well i have been running a 26mm molkt for about 4mouths now and have no huge complaints like others i would try out the oko carb though but also check what happened to me with the flywheel pickups. It is a pain but ould b ur problem

The stock exhaust is way too restrictive for that engine, that might be part of the trouble too, it can't get rid of the exhaust fast enough and it's bottling up in the engine....Not saying that is the whole problem but it might be part of it..

ya it prolly is the exaust but i dont have any carbs to check if that is the prob. and so i should get a 26mm oko. and what exactly should i look for with the fly wheel isus u had?
