I recently bought a used 2004 crf250x and I didn't notice immediately that the rear wheel has a slight wobble to it. I think it's the bearings. Does this sound familiar? Is it an easy, at home fix? Also, some of the spokes are loose and I don't want to mess with truing or un-truing the wheel so does anybody know of a reputable shop in the SF Bay area that will take care of this for me? Preferably on the peninsula or in SF. I dabble from time to time in wrenching on my own vehicles but this is new to me and I don't want to mess anything up. Any advice would be greatly appreciated.
