[370kingR]

Guy i need help. Due to my lack of brain cells i cant for the life of me remember what year yz 250 68mm piston you run in a small spacer plate 265 (sparks style) setup in the trx250r. I think it was an 87 year style but i forget and i didnt save the old piston box. If you truely know for sure please reply so i can order one up for my friend. We built this motor a little over 2 years ago and she needs an overbore...
