Komet Piston port welcome?

[Bryan Carlson]

I have a kart with an old HPV/Komet K-71 motor on it. IS there a class for me? Would it just run with the KT-100's?

we would more than likely let you run with the senior supersportsman class, which is a yamaha spec controled exhaust pipe class, not an expansion chamber pipe. if you have a hpv 3 pipe it would be a closer match for your motor, the hpv 4 is a faster pipe.
