Malossi 135cc kit

Malossi 57.5mm, 135cc kit. Fits 1970's and newer Vespa 90, 90 SS, 100 Sport, Primavera, ET3 and ETS (can also modify to fit on Vespa 50 with new crank shaft and longer studs). Extra 2 stroke power, plus larger transfer ports and a larger exhaust port. Includes BIG bore cylinder, high compression head, CVF flow piston, rings, wrist pin, pin clips, gasket set, Malossi stickers, and instructions. This will bump up your old Small frame in horsepower, and with a pipe and carb, you can increase it much more. (This kit needs the ports chamfered, we can do this for a $35 fee)
