Chain clicking noise - clutch?

[DynamiteBoy]

Hi All,

When riding the bike produces a loud clicking noise from chain. The tempo matches speed (ie faster I go, faster the clicks).

I have adjusted to tight spot, lube chain regularly and have a scott oiler fitted.

If the clutch is pulled in (changing gear) the noise stop, also stops if coasting down hill in neutral. Could chain clicking be related to clutch?

Another point to make is that with bike in gear and clutch pulled it seems like more effort is needed to push (can feel resistance from drive).

Just looking for some good leads / advise before I go tinkering.

Check your front sprocket, mate.

I had this problem on my hornet. It turned out the front sprocket was excessively worn (hooked teeth) and I think what was happening was the chain was jumping off the front sprocket and hitting the bash guard thing. This eventually resulted in my chain having a missing roller and the same pin having a hole through it. I changed the chain and sprockets as a set and the problem went.

Check final drive first as that's the easiest job.

A similar thing happened to me, could also feel the clicking as knocking. Adjusting a bit more slack in the chain helped for a while, but then it returned. I initially suspected it was bearings in the output shaft failing. Turned out my master link was warping and weakening on one side but by such a small amount I couldn't see it, until the chain snapped whilst I was on a busy dual carriageway. How old is your chain/how many miles has it done? Is it a decent make? Are you using a split-link?

Clutches can also wear down and get notches in their basket and the friction plates can wear out as well. Not sure if that produces knocking as it's never happened to me yet (still on the original clutch components and the bike has done nearly 25'000 miles), touch wood!

Sounds like a new c&s is on the cards for you. Check both sprockets and also measure how much your chain has stretched as per what is stated in your bike service manual. Had the same thing on my bandit which turned out to have a knackered chain and a rather fecked front sprocket.
