Default Re: Top Speed, 80cc Chinese motor? what is the record?

I agree with you 100% bairdco...

Ive got two old bgf engines that even with a good flowing exhaust and a couple other mods wont hit 40 with a 36T on the rear of a 24" or 26" wheel.

These two engine will vibrate your fingernail out above 30mph and neither will get over 34mph accept going down a hill

I agree stock china girls with 44T sprockets dont do 40mph in my experience.
I dont always ride WOT, but when I do..I do my best to keep the rubber side down..Ride safely my friends!
