When I washed it last week I noted a little oil residue on the rear rim but I had ridden nearly 1,000 miles since the last wash and changed the oil so I didn't give it much thought. On my way to work today I hit the rear brake and NOTHING! Nice solid pedal but no friction so I checked it out in the parking lot. I've got a leak somewhere around the countershaft sprocket (I guess now they call it a trans pulley) I've got a lot of residue on my belt extending to the rear lifter cover on the rear cylinder. There are oil lines routing around there from the tank so I if I'm lucky it will be a leak from one of them regardless it will take a pretty good teardown and a new belt.

Any suggestions beyond a good visual inspection on how to trace the source of the leak without putting the bike back together?

Is there any common weak point in this area? If it is the countershaft seal it's going to the dealer and I won't waste my time tearing it down.

I've had this bike for a year now and it's been a constant stream of annoying little problems. Worse than my old Ironhead was and it was an AMF!
