I am rebuilding the bottom end of a 2004 CRF250R and just put the shift drum bearing. Now I'm wondering if I installed it upside down. I installed it with the stamped race (i.e. with letters) facing downward. I don't think I can get it back out without destroying it, so I'm hoping it works either way.
Also, for anyone who has replaced their left case, did you remove the nameplate? It appears to be removable but I don't want to bend it all up attempting to pry it off.
