Good day to all of you. I am currently wondering if these two Yamaha parts are interchangable: 3LN-11610-20 (fzx250zeal, fzr250r) & 50M-11610-20 (xv250virago). They are 0.5mm O/S piston rings. As you can see they only differ in the first 3 characters which designate the model that the part was FIRST used on. I got no answer from further studying Yamaha part number theory. Please post what you think!
