Default Re: A new shift concept for the engineers....

Speed record for 49cc is 140mph+

Done with a 6 speed tranny.

My china motor is geared so I dont have to peddle at all, since I removed them. It gets me going from a stand still on an incline on the steepest hills in town in first, and in third it gets me up to 42mph.

This is not using any aftermarket goodies such as an expasnion pipe or high-V carb.

The motor is identical to a HF 52cc, and should pull mid fifties with the pipe and carb upgrades.

I'm going to get an sram 5 speed and go for 70mph+.

It is in the calcs...
