All the ports and dimensions are completely identical to the way Puch built racing kits.
The cylinder has just the right 26mm exhaust port, like real racing kits was buold in the good old days.
This means a significant increase in power.
Racing exhaust is with 30mm tubing
Also castings deterioration is same as in the old days, and not china-nicosil, which is known to lose its breath after a short time.
