    As I understand it, the noise is constant on side stand, correct? What if you sat on it and slowly raised it upright?

      Damn, thats exactly how it sounds. Is this a big issue. How does one fix this?

        No, it's not damaging, just annoying. It can be eliminated but requires custom matching to fit a shim. I think there is a thread about how to do this. The sound is one (or both) camshafts sliding sideways as they rotate at low speed due to a little too much clearance. The sideways oscillation causes the cam to knock against a thrust surface on one of the cam pillows. Some OEM parts diagrams for early GS show a shim to take up the slack, but these were either deleted before or after production began. Never seen a shim in the flesh. When the revs build the sideways oscillation stops and they run quiet(er).

          Here's the thread.

          Let's talk about cam walk, baby... - The GSResources Forums

          This hasn't come up for a while, but I thought I'd start a discussion. The video below is my 1983 GS850G, but the engine is actually from a 1980 or 1981 model. Long story, but this is the engine that's been in my bike for about 40,000 - 50,000 miles. Anyway, these engines are known to sometimes exhibit "cam walk"

            My understanding is that it's the cam walking horizontally and tapping the either the cover or the caps. Try shifting the bike left to right (or vice versa) to allow the cam to float around and see if the noise changes. My 550 will do this once in a while for no apparent reason when it's fully warmed up. I ignore it.
