Hi, i was just hoping someone might have an opinion on how my piston rings should sit on my piston. Bike is a TY250 mono about 84.
Last bike i changed a piston on the rings where both the same but on this one they are two different shapes. One is your traditional ring and the other has an L shaped lip. Just to make it trickier their is nothing stamped on either ring, they are genuine yamaha rings and there is nothing in the manual.
Just wondering what anybody thought about which ring should go at the top and which way round the ring with the L shaped lip should go?
My thanks.
J.
