xr500/wiseco piston
Im installing a new piston in a 1980 xr500. Im using a Wiseco piston. The directions for fitting the rings do not match the rings, they show bevels and and dots, while I have a gray ring marked "n100" and a brown ring with a grey outer edge marked "n100". The gray ring is wider.I believe the markings go"up" but which is the top ring? I cant see any bevels on the inside of the ring. Thanks emti

Markings go up and the ring with the different color side/edge is the top ring.

I installed the same piston in the same motor 6 months ago and ran into the same issue. The rings will only fit one way. The depths of the grooves are different and match the rings.
