97cc engine with mods vid

#21
Thanks for replies, it's really running well, I am very happy with it. Will accelerate up hills, don't feel like I need 5hp Briggs anymore, will turn 5000 rpms quick, hit 30mph easy. Really fun to zip around neighborhood, not so fast to be dangerous IMO.

Mods: re-jet carb (hi/ low jets), drill out muffler, remove easy start bump on cam, cut head 2cc, pocket bike tires (equivalent to 77 tooth rear sprocket), black clutch spring, hydraulic brakes (which I need). Costs less than $100 additional.

:smile:
What are pocket bike tires? And what benefit?
