Topic: '74 550 clunk/click in transmission when neutral coasting

[orange550]

So after getting my bike in tip top shape, of course a new problem emerges. There is a clunk sound, not too big of a sound, but noticeable coming from what I think is the transmission when the bike is in neutral and I am coasting... or if it's up on the centre stand and I spin the back wheel. It's not the final chain, as it's adjusted and well maintained. When I put my hand on the shifter shaft, I can 'feel' the clunk.

It sounds like something 'lifting' up and then dropping into place. It doesn't seem to do it when I spin the wheel backwards. Nor does it seem to do it when the bike is in gear and the clutch is pulled in. I will try to record the sound and upload it.

I checked engine oil, and it's fine. I thought I heard it earlier in the day, then it seemed to 'go away'. but now it's back.

I had an otherwise good, well maintained chain that sounded quite the same. One pin was badly worn and it clunked as it rounded the countershaft sprocket. It didn't seem to when spinning the wheel in the opposite direction.

If you want to eliminate one potential cause, remove the chain and idle the bike in gear. Put a large screwdriver against the case somewhere in the area with your ear to the handle to amplify.
