Title: Yamaha piston ID
Post by: Sorelegs11 on August 09, 2016, 05:53:13 pm

I have a yamaha piston I need to identify it is marked 4V500, it came in an IT250D engine.
I need to get a set of rings for it, the top ring appears to be either slightly tapered or thinner than the bottom one.
Any part gurus have any idea what this is from.
I have looked at a yamaha parts list and this piston number does not come up?
