I have very limited dealings with the Mid Bike engines so far so I'm asking about a possibility. I have seen a lot of scooter motors out there that appear to be ?belt? driven. The one I've been concentrating on is the GY6 a Honda power plant. The one thing I haven't seen is inside what appears to be the belt cover. How hard do you guys think it would be to convert a belt drive to chain? Harley's belt drives have a simple kit they use (Or I think it's simple). The GY6 appears to be a very tunable motor and has plenty of performance parts available and correct me if I'm wrong but I believe there are watercooled and EFI motors out there?stirthepot I'm still on the tire search but in the process I keep stumbling across other STUFF. Wellcheers

I don't think it would be hard to convert.But you'll loose the top end speed.Because as of the cvt setup.You know as the bike goes faster the belt rides up the pulley changing the gear ratio.Sorta like shifting with no gears.

I wondering about GY6 for reasons other than the CVT. I also want to know if the parts are inter-changeable with Honda's XR or Lifan's clones

they've got to have different cases with the cvt and all.

I was thinking the CVT would have been designed around the old case design in the beginning then a new case build to a better standard later. That's usually how the Japanese did their engineering when these motors where first going through their evolutions. There has to be period where the parts were close enough that a little elbow grease will get them working? You can't fail unless you don't try.

i think ill stick to a chain
unless you find a shaft drive

I want it as a chain drive also. I was wonder about the conversion from a belt to a chain. It looks like a belt travels down the cover and connects to a second shaft unit which drives the wheel not a chain.
