The cam chain on a buddy's '04 KLR650 seems to be slipping but we can't get to the sprocket without removing the rotor bolt. I've got his bike in Smyrna (NW corner where 285 hits 75). This is the only form of transportation he's got right now so it's pretty important that he gets it on the road soon. I'm free all week so if I could swing by and borrow it we'd really appreciate it. Also, I'm not a KLR guy. If anybody has any advice on this I'm all ears thanks!
