Tonik 50cc 4 stroke Chinese Scooter. I am trying to get to the piston because I beleive they need replacing. I cannot get the valve cover etc...
I have bored my cylinder because it had a few spots but i used the old original piston because it was still good. Now i want to change the piston...
just bought what I think is a 50cc malossi kit but it looks quite big for a 50 can a 50cc piston have a diameter bigger then 40mm?
