does any one else have this motor its the alloy racing head with 4 spd manual clutch w/ oil cooler...and what gearing do you find the best? also how did u mount your oil cooler to your frame

 

I don't have the alloy racing head, but i do have the lifan engine with no oil cooler; i didn't find a need for it because im not racing the bike, i'm using it to stunt, but that's just my opnion and it would be a mess if i wrecked and broke the oil cooler, so i'll just leave that one out. For gearing i left the stock 37 sprocket, its perfect for whoolies. The oil issue you can just use 10w-40 and i wouldn't recommend over filling it if you are going to stunt because all of the extra oil is going to come out of the overflow and spew on your back tire... just my

 

5w 30
