ChinesePartsPro 99014 70cc Two Stroke Big Bore Kit with 12mm Wrist Pin and CDI, Coil Carburetor Filter

The carb came with a 75 main jet. The cylinder head and piston is a genuine Yamaha jog 70cc :) the motor is made to be 70cc and only bored to 50cc for the U.S. etc. Probably the best kit for the money..just doesn't come with a new wrist pin bearing. They're like five bucks make sure to get one. The exhaust gasket is a little small and only half metal..will probably use old one; got it cleaned up.

Seems to be a good kit. Could use instructions for some and specs on the carb. Don't know what size jets it has or anything else about it.
