i have a 97 kawasaki 100 dirt bike and my rings and piston have gone bad.. i dont have the money to buy new ones or used ones. so could i use a piston out of a lawn mowe or 3 wheller or 4 wheller if its the same size as the dirt bike piston?
no. the piston in a two stroke is different that a four stroke piston, and a lesser one will not stand the R.P.M.s that a two stroke is capable of. look on e-bay for a used one. but always use new rings and gaskets. a two stroke absolutely cannot have any vacuum leaks or blow by if you expect it to run good
