Really? I'll let mine work on my UC - although I do all the routine maintenance myself, it's NOT because I don't trust 'em - I just enjoy doin' it, and have the tools, books and knowledge to do it - AND know when to call in a pro. I've seen way too many Indies AND owners screw stuff over the years.
So....know who's gonna work on it, make sure they're qualified - but just because they work at a dealership doesn't make 'em fit - or unfit - to work on your scoot.
