I recently noticed that when I applied the rear brake on my '75 750, the rear tire would move to the right. The bike always felt a little shifty to drive since I can remember, but I ass-u-me-d that the older bikes just rode like that.
After a little inspection and a look at the exploded view diagram of the swingarm assembly I figured out why my rear end was sloppy. As most of the posts I searched suggested the first thing I planned to check were the bushings. This was not the case. It turns out I had mistakenly installed the swingarm incorrectly. What I had done was mistook the end cap/dust seals (11) for washers. Instead of installing them on the end of the swingarm, I put them between the frame and the blot/nut. By doing this, the swingarm had roughly 1/4" side to side travel...
Now that it's installed correctly, the bike rides true and slop free. I am now confident in my cornering.
So in conclusion, be sure to double check the diagrams
before final assembly!
Thanks,
Chris
