At ~15,000 miles the chain derailed and poked a hole in the crankcase...repaired it with JBWeld and it has held for 10,000+ miles. Unfortunately, nobody makes a sprocket cover that would protect the case. Second problem I had was a rock sheared the two screws holding the sidestand switch to the kickstand plate, leaving the switch dangling by its wiring. I backed the broken screws out of the plate and replaced them...seems like the bash plate should extend a little to the left to protect that switch. Fortunately, the switch isn't that critical...
