Zuma moped engine upgrade’s

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. The kit includes 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.
