    Project 1998 GP800

    HI Guys

    Wondering if you can help me out. I am in the process of rebuilding a 1998 gp800. One cylinder was shot so I ended up purchasing a set of cylinders off ebay. The cylinders appear to be identical but the power valves have 2 very slight differences. One has a groove arould the brass bushing and this same valve has a slight chamfer. My plan is to use the 2 with the slight chamfer.

    Does anybody know at what year this changed or why ?
