Malossi 70cc Big Bore Cylinder Kit for Minarelli 2T Engines
This Malossi 70cc cast iron cylinder kit is built for horizontal, air-cooled 2-stroke Minarelli engines. Compatible machines include the Genuine Buddy 50 and Yamaha Zuma 50. Moving up from 50cc to 70cc gives noticeably quicker acceleration, more low-end pull for hill climbing, and greater overall output. It is one of the Minarelli 50cc / Yamaha jog scooter parts that can boost performance for off-road use.
Components Included
The kit covers everything needed for a top-end rebuild. You get a cast iron cylinder, an aluminum head, a piston with two rings, a wrist pin, two circlips, gaskets, and reed petals. The parts are matched so they work together as a set.
Installation Notes
Confirm that your engine uses a 10mm wrist pin, since this kit's piston is sized for that pin. If your engine takes a different pin size, you will need to buy a suitable piston separately. After fitting, plan to up-jet the carburetor by 10-15% to keep the fuel mixture correct.
