Or....

You can take the easy way out for power and bolt a 6.5hp Briggs to a trailer on the back of the bike.

Plenty of guts, trust me here!

Does the 80cc have a "balanced" counter on crank

from what I have on heard...the counter balance is not balanced. Any Ideas if this is true?

My hands tingle after a 4 mile ride...Uhhh, I also have rubber pads at mounts.
Maybe some gel pads on palms?? (joke)

its not possible to balance a single cyl engine

and the brigs and stratton has one flaw...no torque
im getting to about 7 horse with my curent set up but i just bought a 48cc engine kit and i think that if i make a new crank for it and get rid of the silly gearboxes they have that i can make about 12thou rpm and have over 4hp easy i also by accident stumbled upon a way to make these bikes super quiet without loosing power! just wait till i get my site up i have some goodys for everyone!-TG
