Hi there. I have a year 2000 cb500. Just recently i have noticed a quiet, random ticking noise coming from the engine. Its not a knocking and doesnt seem to be affecting performance. It is not there when in neutral or with the clutch in. It sort of sounds like there is a small stone inside getting kicked about. I can hear it in 1st and 2nd but after 2 and a half thousand revs i suspect the engine noise covers it over. I have checked oil level, i have cleaned and checked the chain. Both are fine I did recently drop the bike, not sure if that's coincidence. I also stupidly pulled away with a chain still on by back wheel, no lock, just the chain so that pulled around, only one turn of the back wheel. That's the only two stupid things I've done. Other than that i use the bike to commute around London. Any thoughts on what could be the problem would be of great help. Thanks in advance.
