Zuma moped engine upgrade 70cc kit Polini

This is a Polini sport 70cc kit for a 2 stroke Yamaha Zuma any of the 2 stoke horizontal motors 2002-2009. Upgrade the stock 50cc and keep the original carburetor. Cast iron build not an aluminum race set up. This is supposed to be for increased top speed and high reliability. The kit is brand new unused. New piston with rings and cylinder 70cc.2 stroke motor kit.The kit includes new cylinder, piston and carb jets to set it up correctly and a hi flow UNI air filter. See the picture. I sold the bike and no longer need the parts. I went the eBike route. Number is in pictures.
