I had the same problem when I got my 05 636 inspected, my problem was the first inspection shop I took it to, wasn't a bike shop, and they nailed me with rear fender new rear turn signals and a new taillight (they said my "Stock" taillight wasn't red so it had to be replaced). I ended up taking it to an actual bike shop 2 days later and when I walked in to ask them about these things, they said the taillight was fine the turn signals were fine, and no rear fender needed because my exhaust "stopped debris from flying up" and that the other shop only said that because they were going strictly by the book and didn't know shit about bikes.
In case your close, I took my bike to Twigg's (
