weracerc,
I feel for you. I just did a rear replacement, and didn't have much trouble, except I tried to get my spacers mixed up for a bit.
But from your post, and against what others have said, I am glad I chose not to go w/ the -90.
Using my Van to break down the bead, the old tire came off relatively easy, using tire irons....along w/ a rubber tire hammer and silicone for getting the last bead off.
The new dunlop was a lot heavier tire, and gave me a little challenge, but using my right foot only and the rubber hammer,....(no tire irons) and lotsa spray silicone, it went on quite well,......after I adheasive siliconed the spoke strip in place. But I had a little advantage in that I was working in a truck tire shop when I was 15 yrs old,......I learned a lot, and didn't forget it.
I would never asvise anyone w/o experience to change a MC tire themselves !
The broken brake arm,.....I just don't understand that, as the complete brake hub assy is removed first thing.
On edit, the belt hub fell out of the wheel,.....tried to hurt my foot !!
