  • Drive Shaft Boot

    Hey all, I bought an 80 1100 special and the big boot covering the shaft u-joint is cracked,was wondering if one of a 78-79 would fit an 80?Thanks:Rick
    1980 XS 1100 replaced the seat and sissy bar from a XS 1100 standard and changed the handle bars. Did not like the original bars at all.No mod at all except for a four into one header.

    Yep... any of these off any XS/XJ11 will fit, and Yamaha used the same boot on some of their smaller XS/XJ shaft-drive bikes, so you have lots of choices...

        Yeah, it's a bit of a PITA to change. If it were me, I'd pull the boot out of the way and disconnect the driveshaft at the middle drive, then pull the rear wheel and final drive. Push the driveshaft back, change the boot, then reassemble. I think some have managed it by just disconnecting at the middle drive and pushing the u-joint back on it's spline, but that can be a real battle...

          Better yet, take the swing arm bearings out, clean them, regrease them, and while the arm is loose, put the new boot in.
          When was the last time you checked the swing arm bearings? CZ

            Easy way

            Just undo the universal from the middle drive and it will move back far enough to replace the boot. No need to drop the swing arm. Only 4 bolts removes the universal.
