+100 on the Marc Parnes balancer. Hassle free, well made, easy to use, accurate.
I built a tire change station out of a 14" car wheel and a 2 foot long 5/8" threaded rod with washers, nuts and a couple pieces of wood. After scratching a MC wheel with just 4 layers of duct tape padding the rim of the car wheel upon which the motorcycle wheel sits, I bought a piece of washing machine drain hose, and carefully cut it lengthwise with a hooked utility knife blade before fastening it over the car tire rim -- it works GREAT now.
I have one tire/wheel left to mount -- the rear 180/55 - 17 on the gorgeous but easy to scratch rear Carozzerria custom wheel for my '03 XX. No problem with yesterday's mount of the front 120/70 - 17 Carozzerria (not a scratch and it went pretty easy), mostly due to a few things: I'm getting MUCH better at the process some 5 tires later (5 removals and 4 mountings so far), the drain hose padded mounting station, care to duct tape and use a cardboard cutout in the well of the rim to avoid scratches from accidental drops, AND 4 great rim protectors I found at a local MC specialty shop (don't know who they're made by).
The blue Motion Pro rim protectors are just too soft, and they tear up easily, leaving no porotection. Rim protectors made from heavy plastic containers have their uses, but won't stay in place, aren't thick enough and are just not handy enough to the process. The ones I bought are a yellowish white plastic in the same shape as the Motion Pros, but of a harder plastic that is perfect for the task. I use 4 -- stringing two each on two loops of nylon cord, put the loop over the 5/8" rod at the center of the changing station and the two attached protectors on the rim. That holds them in place, and I place the two paired sets at about 1:00 and 3:00 on one side, 9:00 and 11:00 on the other for installation.
Gotta get out to the garage and mount that last tire now. . . . . . . . .
(EDIT to add: Amazingly, that 180 Pilot Power on custom wheel was the easiest and fastest tire mount I've ever done, even including the days of tubes in my bike tires!! Then, thinking about it for a minute, I realized that I have to pack my garage up for my move and that there was really no useful life left on the FJR's badly cupped front Stone, so I also replaced that with a new Pilot Road. Six tires off and six tires on, two installs of which are on custom forged aluminum wheels, and unlike my feeling after the first couple wheels, I now feel like the process is almost easy. Glad to be done with removing and mounting tires for a while now, though.)
