Model: 140cc Engine Motor
What you Need to know!!!!!! FIRST DONT RUN OIL SEND IN THE ENGINE!! Use a friction molly addictive 1/4 of the cylinder and with ya 5w40 oil just 1qt is enough these engines don't take much. NEXT CARB!! I USED Angrebuild VM22-26 carb with a jet kit I ran 140-150 is ideal If not you will run lean! Blue Box Timing kit 17t-45t rear sprocket 55-60mph all day long with a full slip on and exhaust pipe also air mixture screw blk looks good in my a opinion also carb adjustment sec from the top! Slot for the needle.. Have FUN!! It's a ripper!!!

Started and ran great for the break in period. Started leaking oil and found the rear case at lower motor mount had a 3in crack. I put sum jb weld on it just so can ride the chi-na grom I put it in. Leaked a wee bit and did a 4hr ride. Conservative rpms. Started running poorly omw home. Lost most of its power and wouldn't idle.Carb is fine and engine has lost compression.

The media could not be loaded. Very simple I had old one out and new one in about 10 minutes. Started right up.. 2 things I would like to see this kit have is exhaust crush sleave.. also a clutch lever and cable. It's a direct bolt into bikes that don't have clutches.. time to put my tires on another successful build
