[QUOTE="dirt bike dave, post: 1430337, member: 18302"] Sounds like the big end bearing is shot. It happens, but repair is costly and may not make economic sense. If you don't repair and it lets go, it will probably take out your cases, and the shrapnel can easily destroy your cylinder, too. Splitting the cases and re-assembly can be a pain, but is doable. Some bikes do require specialized tools, but you may be able to improvise. In case you don't know, the connecting rod is one peice. There is no cap like there is on a car connecting rod. You cannot replace the big end bearing without pressing the crankshaft itself apart and sliding the rod off. The new rod and bearing gets slid on, and the crank re-assembled and pressed together. That's a job for a specialist. If you don't have one in your town, you may be driving, or shipping your crankshaft to a specialist. An alternative is to get a replacment crank/rod assembly. All new crank, rod and bearing. Might be hard to find and expensive, but may be worth considering, because you could reassemble it all yourself. When I blew up a '99 CR250, it was not much if any more expensive to buy a crank assembly, because Honda had pretty fair prices on them. If you are going that deep into your motor, you should replace the crankshaft bearings (the ones on the ends of the crank, that fit into the cases). And you'll need a complete gasket set. You are going to rack up a big parts bill, unfortunately, even if you do your own labor. [/QUOTE]
