My FS650E 2001 mod has now got exactly 200 hours on it. All the riding has been done on tarmac road.
So i opened it up to change all the bearings, but ended up changing a lot more.
New exhaust valves, new con rod, new clutch basket, new starter gear, new de-comp gismo.
Old piston and piston ring were re-used. Gap on the piston ring was 0.35mm.
Her is some pictures of what i found.
Piston, measured to 99.95 mm.
Liner
Main bearing, please note that the inner race has slipped on the crank shaft.
Old con rod
cam shaft
de-comp. If you look closely, you can see that it is worn.
More pictures.
