Default Re: i think my "80cc" has issues. top speed only 28mph with shifter kit...

ok i port matched the exhaust side, and test drove it, but its always more difficult to tell if there is any gain at night (it does feel stronger but it is colder tonight which could be helping).

will give the intake side a porting tomorrow, think i will bore out the intake manifold a bit as well.
