Hey guys, my machinest is helping restore a '73 YZ360 short track bike--that he actually built back then-- for the current owner and are in need of either a new standard piston and barrel or a new .080 piston. Or maybe a complete engine either YZ or MX. Evidently pistons are NLA for this machine. I guess the standard barrel was plated but the one they have now has been sleeved hence the need for either a good stock piston and cylinder or an .080 over piston. Please let me know if you have anything or can point me in the right direction for parts. Thanks! P.S. I put this post here rather than the Flea Market because the people who frequent here are more likely to have the knowledge of what I need.
