I have a 1983 PA 50 ii that I restored recently, it is a complete bike and looks amazing zero missing parts. I love the ride and it is already fast with the Proma Exhaust I put on it, i hit a top speed of 39.93mph today riding in 80 degree weather (nothing better). I would like to get another 5mph out of the bike if I can.. i know that using a 50cc stock engine is already almost maxed out at 40mph but is there anything I can do other than a kit?
Any help or pictures/detailed diagrams would be much appreciated! Thanks in advance!
(want to make my PA50 II faster without a kit.. already have an exhaust)
