Cylinder at its widest point measures 69.
Very nice cylinder, and rare. 319mm, so i'd think going to 1.
5mm oversize would be in order for optimal performance. Looks like minor scuffs on the cylinder surface is most likely from a previous owner not letting engine warm up before it rip, and piston grew too fast. Removed from: 1991 Yamaha YZ250 with miles please review all pictures to assess the condition of item.
Piston fits nicely in cylinder, and is included, but i'd recommend a replacement.
