What's inside your 900 swingarm?.......
This rusty junk is what you'd typically pull out of a stock
1973 thru 1977 900 swingarm....
Most are not this bad, but few remain in working order,
the way they were intended to be.....
When new, the flanged bushings were pressed into the ends
of the swingarm......
The bearing sleeves rotated inside them, and the center
spacer maintained distance
between the sleeves....... Over time, the sleeves freeze
up in the bushings and at that
point the arm is, for all practical purposes, without any
pivot bearing at all.....
It took an hour with a sledgehammer and a blind-hole puller
to get this junk out....
But once out, and the upgrade kit installed, you have a
very nice setup....
WAY better than original.......
