Hi, Iv recently bought myself a superstomp 125. I intend to race it in the winter series supermoto. Iv read about loads of different engines and just want to know which engine this one is. All gears are up. I'll be racing with some 125s but mainly 140s so was thinking of bolting the 140 head straight on if that's possible? Bought the 125 at a third of the price of the 140s. The casing says stomp and 124 gongyu is wrote on the head.
If you look at the engine number under the sprocket.
It will tell you the piston size ie 52 or 54mm
But yeah mate it will either be a 120 or 125 not that there is anything in it lol
post a picture and the knowledgable fellows on here will be able to help. as far as i know you can't put a 140 head on as the stud patterns are different
