Guys,
Howzit? I spun a rod bearing on my 95 CBR 900RR. I found some rods and bearings on ebay for cheap. I also found a crankshaft but after purchasing it I found it was for a 96, it wont work for me. Now, on a low budget already, I need to unload this crankshaft and get another.
My question is, can I resurface the crankshaft or micropolish it where the rod bearing spun? or do I have to buy another one. If I can, do they sell oversized bearings to compinsate for the difference? Any help?

How bad is the crank? From what you wrote I'm thinking it's shot pretty bad. I'm sure the crank can be resurfaced but you'd have to take it to a machine shop. It would be almost impossible to do this at home -- just too hard to keep it perfectly round. I haven't heard of undersized bearings for the crank -- you could call Carillo or Ape and find out from them what they recommend. Sorry -- not much help I know.

Its actually not that bad. The rod took most of the damage before it locked up, but there are scratches I can feel with my fingers. I wouldnt attempt it myself, but I wouldnt trust the machine shop for an honest answer. The bearings (I imagine) would need to be thicker to compensate for the resurfacing? Or maybe they would be ok as long as the rod doesnt have play in it? I emailed the parts place, well see what they have to say (voicemailbox was full). Who is "APE" and "Carillo"?

Another member helped out, he had the same prob. He said APE is welding it then milling it back to stock. Sounds good to me. Thanks for yur help though
