We'll see how well Adventure in Dover, Oh does this week. It's got 700 miles worth of bugs on it and I'm not cleaning it before I take it in for it's 5k service this week.
Schaeffers above Reading PA does. They did a so-so job the first time but I rushed them. The second time I think it was cleaner than when I bought it, so they nailed it on that try. I gotta take my FL in for some ESP work soon so we'll see how good they are. There's bugs on it from october yet. Its not too cold to ride but it is to wash. (No garage... just a shed)
On the rare occasion my bike went to the dealer (usually warranty item) they washed it once. They did ok but I told them not to after that. They used the air blaster blower and it dried a lot better than my leaf blower does though
