Down under where your kickstarter shaft goes into your engine case there is some numbers and letters, this is your engine code, the top number/letters is the engine type, if it reads 1p52 it has a 52mm piston if it reads 1p54 then it is a 54mm piston, well in actual fact the 52 and 54 is the width of the barrel and the pistons are slightly thinner in width than that, but when purchasing pistons there normally marked as the reading of the barrel, so you would look for a 52 or 54mm piston.
