So I purchased a 2004 crf250r about 3 months ago. I thought I looked it over pretty well when I bought it but recently I was giving a good old fashioned cleaning, like really detailing, and I found this crack on the left side case where the clutch lever/actuator is. It's hairline and not leaking but I am curious to know if anyone else has seen this or knows if this is common or perhaps just dumb luck for me. FYI, the bike runs like a champ and I'm happy with it just a little nervous about this crack. I have heard that JB weld could be used but I think I would rather just get a new case and prolly end up doing a full rebuild. It's only my backup bike/ loaner to friends and family so I'm in no hurry to dump a bunch of money into it.
