I am re-ringing a 98 400 and the new yamaha piston rings are two different colors. One is black/grey and the other is a dark tan color. What ring goes on the top? :cry: thanks very much

Most of the time the dark tan ring will go on the top. They are both compression rings it really doesn't matter. The dark tan is a coating on the ring. Just make sure you put the ring end gaps in the right spots and torque that head down right.

As it turns out the rings are different in thickness and could only go one way. thanks
