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.
