hi there i want to rebuild the topend in my bike. is there anyway to find out what size piston i need rather than taking it to honda and getting robbed. i can see them charging me to measure the cylinder. and then charging me 200 dollars for a oem honda crap piston. and i dont wanna buy some crazy tool to measure it myself that i dont know how to use. is there any markings on the piston that will help me. maybe i just have to get robbed by celigh honda like i have many times. the last time i went there they charged me 60 dollars for brake pads that barly lasted 1 mounth. does anyone have any advice that may help me. ... no smart ass comments please. thanks guys cheers!
