I have a 2000 Polaris Indy 500 Classic. I have changed all the bearings in the chain case. New seals, ect.. The chaincase is very hot and there are some metal shavings in the oil. You can't even put your hand on it. The chain is finger tight and nothing seems to be rubbing. I can't think of anything else that would be wrong with it. Any help would be great. I'm puzzled.
