Default 2 stroke shift kit with 4 stroke engine

Sbp's 4 stroke kit is only available for the 49cc engines, so I was wondering, if I installed the 2 stroke kit onto the mount for, say, a 212, would it work? If I filled in the gap for the seat tube with a rubber plug, and installed the jackshaft mount the same way I would with a 2 stroke? Just curious, but I'm going to try anyway.

Default Re: 2 stroke shift kit with 4 stroke engine

I run a shift kit with a KTM 50 (9hp) and have had good results but Im pretty sure the torque of a 212 would be too much. I had a chain stretch issue on the secondary drive chain until I went to a wippermann chain. I also added a downhill mountain bike front chain guide to keep the final drive chain from jumping off but I only had that happen twice until the new guide.
