Recommended Posts

i have a 1998 yz 80 engine in pieces. i need to order a piston for it but i dont know the correct size ( previous owner says it was bored over). and the piston that was in it is missing. how do i figure out what size piston i need? the cylinder diameter is 49.00 mm. any help would be greatly appretiated. my guess is that it is 20 over?
