I changed the rear tire on my RK. Not as bad as I thought
at first, had to pull the mufflers and modify my floor jack
to get it high enough. The hardest part is breaking the bead loose, mine are tubless, but it's not hard to get off and on the rim. I scratched mine a little, not really noticable though. To balance it I used a piece of threaded rod and two small bearings that came out of a small elect motor, tightened up against the wheel bearings, they fit inside just a little, put the rod between too jack stands and let the wheel roll till it stopped, add weight till it dosn't stop in same place twice. Took some time, but I like to do stuff myself, if I can. Hope this helps.
