I had my clutch side cylinder go down this last weekend. Took it apart and the top of the piston is peppered but no signs of the cause. Rod bearing good. Crank seams smooth. There is about 8000 miles on the crank since last rebuild. What would you guys do? Put it back together and go? There is done flaking off the cylinder so it needs a new jug. Would a chunk of nikasil pepper the piston like that?
