New to the 01 650R. Changed the oil and found brass/ bronze shavings in the oil so I'm thinking crank. Bike is apart. The thrust washers are intact. The connecting rod is worn but the wrist pin is fine and in spec. Can the bits of metal be from the of small end of the connecting rod? Another question? It almost seems that something is loose in the crankcase? The inside of the case at the bottom is nicked up, the outside of the cylinder is nicked and the cam is scarred in one spot. The inside of the cylinder is a little scarred, but the piston is good. Its like something is moving around with the oil. We're going to check the cylinder specs and see if its causing the rod end wear or is the worn rod end affecting the piston? I'd like to put the bike back together, change the oil regularly and enjoy the bike. Only had it two weeks, one ride, and trying not to feel totally screwed by the former owner!!! What do you think?
