1975-1076 CR250 Elsinore - Used Cylinder (71mm). studs are in nice shape. One corner of a bottom fin broken off (see picture). Vintco sells over sized pistons for this bike and they also sell sleeves for it as well.
**** I will be listing a ton of parts for the 73-77 CR125 & CR250's. If there is something in particular you are looking for let me know, I have motors, ignitions, hubs, center cases, restored tanks, etc.
