I've decided to do a full rebuild on the my 03 CR 250R. What are some good links that people would recommend/videos for walkthroughs? There is one on that is on youtube that is, ok. Doesn't mention anything about the crank (I think it is end play?) and how to check that. Ill keep the post updated as I work my way through the rebuild, assuming I have time. Im only home on the weekends so it should make things... interesting.
