Hey all,
Just recently the following's started happening to my GS500; when the bike warms up and hits exactly 1500 revs it makes a loud popping/knocking noise and the revs drop briefly, before climbing back up again (then the cycle happens again almost immediately.)
Anyone heard of this before/have any idea what it could be?
I've had the bike into a garage to have the valve clearances done (there was 0 clearance and they had to be adjusted and checked again)
Yesterday I balanced my carbs and gave the bike an oil and filter change but the noise still persists.
I've heard that the camshaft can 'walk' on my model of the GS500 (2001), and make a knocking sound. But I was assured by the garage that did my valves recently that this isn't the case.
If it's any use at all I'll record the sound that the bike's making/look on Youtube for an example.
Thanks in advance!
