PS: Don't buy the 4 stroke kit from the Berry cause the gearbox is junk.
Get a 4G like KC said.
Ya, the bicycle-engines.com kit is a real Skyhawk 142F-1G / 4G kit, 2.5L tank and all, a good buy for $300 5:1 gear ratio reduction.
I was paying $350 for them back when gasbike had them.
If you aren't in a hurry and couldn't care less about CA law regarding gears I'll be releasing a kit for 4-stroke shifters in a month or so, with a 3-speed internal hub really just an ideal machine.
A month or so before I have the parts here.
