Well, I finally got the Goodyear installed. It was a battle! Just getting it in place took some soap on both sides of the deflated tire. Then it was time to take care if the interference with the swingarm / driveshaft housing.
First, I ground some of the excess aluminum from the casting parting line on the swingarm - that got me maybe 1/16" or so. Then I worked on the tire. When I inflated it to 28psi, it got slightly narrower, having a little less interference. But it still needed to be narrower, so I burned some rubber! I tried 100 grit sandpaper with the bike running in 1st gear, but that was kind of slow, so went back to using the same grinder, as (shown in the picture). It still rubs a little bit, but I think a little riding will take care of that.
So, now it's time to give it a run to see if it handles differently than the General Altimax that I had before.
