    Low speed knocking noise

    The 82 550L developed a new noise yesterday.

    Noticed it at low speed as I was riding into my driveway.

    The noise sounds like I had something stuck in the rear tire. A slight knock every time the tire rotated.

    After I got off and put it on the center stand the tire didn't have anything and the noise didn't happen when I rotated it by hand or when I coasted on the bike. It seems that it needs to have motor pulling the bike for it to happen.

    I'm thinking chain/sprockets or rear bearing? Both have many miles.

    Likely the chain and sprockets are shot, the bearing are easy enough to check as well.


    Life is too short to ride an L.

      Put it in first on the center stand and apply a bit of rear brake to add a little load and see if it reappears.

      I would rather trust my bike to a "QUACK" that KNOWS how to fix it rather than a book worm that THINKS HE KNOWS how to fix it.

        Loose chain bouncing off the swing arm at the frame point will make noises too....and leave raw metal to rust.
