Re: i think my "80cc" has issues. top speed only 28mph with shifter kit...
thanks for the advice guys. i want planning on doing any porting or anything until atleast 2-300 miles. i was just trying to get advice on how to port these engines as i am not to familiar with modifying 2 stroke motors. my intake port is oval in shape and larger on the motor side but round at the manifold, so should i make a custom manifold that's the same way, because from what i can tell the intake port is oval all the way into the cylinder, and a little larger, but as you know the stock intake manfold is round and not enough material there for me to grind away to a perfect or almost perfect match.
The exhaust port looks like i can easily match up, i need to take another look at that and make sure.
But i think the first mod i do will just be a tuned pipe, seems like that gives the best bang for the buck.
