NSU screws- one tight, one backing its way out with only 3,000 miles on a 2008 bike. I would definitely check this on any DR.
Stator failure at 28,000 miles.
Rear brake light assembly vibrated loose at about 16,000 miles, then the steel mounting bracket broke from vibration at 30,000 miles. Luckily ADVGrifter had sent me a replacement for it- free! Thanks, Grifter.
