I recently rebuilt an 80cc engine and did a few mods to it. I ported it and polished it and trim the skirt of the piston on the intake side and added a velocity stack and holy crap what a difference!!!

Stronger faster take offs and definitely higher stronger top end.

It is Definitely worth the time if you have a new motor, I strongly suggest you do this to it!

I still can't believe the difference it made! Its incredible!
