Have you run into this?

At a RAA a couple of years ago we found two Rockets with incorrectly installed rear brakes. The bolt that stops the callipers from spinning round was not bolted into the hole. Fortunately both of them were done in such a way that the callipers would not rotate forwards, but if the rider were trying to use the brake to stop the bike rolling backwards down a hill then it could have got very nasty very quickly. IIRC both bikes had been incorrectly done by dealers.
 

Or you can just use Dyna Beads and be done with it. I've been using them for years. Not only do they work better than wheel weights, they don't ugly up your wheels like wheel weights do...
 
If you have even a little bit of mechanical skills, it shouldn't be too difficult to remove the wheel from the bike yourself. I picked up a lift with a coupon from Harbor Freight for less than $100. I remove the wheels on my 109 myself and then take them to a local Victory dealership. I had my wheels chromed so I needed to take them to a place that has the plastic tools so not to scratch the chrome and they have them. They charge $25 a wheel to dismount the old, and install the new tire. No need for balancing as I use Dyna Beads which I install myself. It was well worth the purchase price of the lift so the dealership doesn't need to take the wheels off of the bike...I also like to support my local businesses, so long as I can get what I need at a reasonable price...
 
I've had rear tyres from Rocky Mountain posted to Australia in 3 days, had em fitted and balanced and still come out in front by nearly $100.....love em.
