Default Re: The Pocket Bike Engine and Your Opinion...

I ran this engine on one of my prototypes, they are more powerful than the 49 china as they have full bearing construction and run reed valving. I ran a jackshaft and managed 50 mph top speeds. This requires disk brakes and a strong frame. I found out the hard way that a bike frame is not up to the stress of this kind of speed.

I have just modified the motor for ethanol/castor mix (as I can get pure ethanol from work), I raised the compression, hotter plug, drilled the jet out to 1mm and i'm trying to adjust the timing now. I would like to fit it to the next build, a bmx framed cruiser.
