Zuma/Vino 10mm Pin Malossi 49cc/50cc to 72cc Big Bore Cylinder Kit

If you are looking to get more power out of your 50 2t scooter, this big bore kit is the answer! The install is fairly easy, and bang for buck, it's the best out there. This kit will convert your engine from a 49cc to a fire breathing 72cc :-)

The takeoff speed will feel twice as fast, and the top speed will increase. Most importantly, you won't loose speed on hills. You may need to re-jet the carburetor to adapt to the larger displacement on your scooter. One thing that you must do after installing, is add a cap full of oil to to your gas tank (about a 1 oz) every time you fill up at the pump. This is very important! The oil injection pump on your 2-stroke is made for a 49cc scooter, and you will be installing a 72cc. This will ensure your motor is getting the extra oil it needs.

This Malossi cylinder kit is made in Italy by a company that races scooters, and is top notch. This kit is made from laminate cast iron. It has a recalculated heat exchange surface and a much larger and smoother transfer and exhaust port for maximum efficiency. The piston pin is reinforced, and the pistons alloy aluminum is made with a high silicon content. This kit is not only more powerful, but is made to last (as long as you add that extra ounce of oil at the pump).
