[QUOTE="15mccoth, post: 191251, member: 3135"] Does anybody know how to clean the bearings in the bottom end. I split my case on my 2000 yz 250 and while using grease lighting to clean the outer part of the cases the bearings seem to have gotten some dirt in them. Tried to spray them down with grease lightning and also tried spinning them and also using a compressor. Nothing seems to work:/. I was thinking maybe when is all back together just fill with cheap oil and run for a bit and drain oil that hopefully will catch all the dirt. But I am having a hard time putting my cases back together knowing there is some stick in some bearings (my piston skirt also blew into pieces littering my motor with fairly large shavings so there could be some in the bearings too). My dad said bath in mineral spirits but not sure if that is good for seals and bearings. I NEED HELP WITH IDEAS [/QUOTE]
