Well, only since I was asked to throw in my 2 cents. I live about 45 minutes south of Reno (until just about or just after the time of WFO). I also do most of my own wrenching and tire changes, so my input on the specific issue isn't what it might be.
The Yamaha dealer in Reno is Michael's Cycle Works on South Virginia St., which is maybe 5 or 6 miles from the Hilton. I have never dealt with that store, but bought my FJR and have done substantial business (mostly parts) with their other store in Carson City (which carries Honda, Yamaha, Suzuki and Kawasaki). While they have always been cordial and pleasant, their prices are always the highest of anywhere else I might go, they won't deal on bikes and my one service dept. experience (rear tire, plugs, and some specific requests on my 97 XX) was expensive, incomplete, poorly done and resulted in me leaving the bike several days longer while they figured out the vacuum line (to the tank) problem I told them they had created. They tagged me for $205 for a Pilot Power and then charged me another $95 to take it off the back of the XX (not hard) and mount the tire. I needed it done, wasn't able to do it myself right then, and wanted a few other things addressed, so I left it and my service manual with them. When I came to pick it up several days later, they took my money and gave the bike back to me, unrideable, since the only thing it'd do was idle, AND they completely blew off checking a couple other things I'd asked them to check and fix.) So, I'm going to have a hard time recommending Michael's for service work.
So, if I'm in Reno and it isn't a Yamaha specific part or problem, I go to Big Valley Honda (which, BTW can be seen from the bike parking area at the Hilton -- a half mile away). A riding buddy has had his XX's tires done at BVH a couple times (after Michaels (Reno) installed a 190 on the stock 5.5 inch rim the first time he replaced a rear tire (like the FJR, it takes a 180, and a 190 makes it squirrely on less than a 6 inch wheel). The Kawasaki, Ducati, HD and Buell dealers are within 100 yards of BVH, too.
IF I were coming from far away, and if Sunnyside wasn't coming with a tire changing station, I'd probably call BVH ahead of time to make sure they had the tires in stock for me. Once at the meet, I'd either bring them a photocopy of the H. Marc/WC wheel removal pages OR take the wheels off myself at the parking location (meaning tools along) and find a way to hump them over to BVH a half mile away to be mounted and balanced.
