Is it an OEM chain and sprocket kit with a rubber damped front sprocket?

If not it will be slightly noisier than stock :)

Hi thanks for replying changed it to a steel one and i think i tightened the chain to much and after a ride come back slackened it off but still noisy and quite loud . Is there a bearing behind the sprocket and if so would it be a engine split.thanks steve

There is a bearing on the output shaft that would require an engine split to replace, however i think it's extremely unlikely you've damaged it given the short while the chain's been run tight.

The rubber damper on the OEM sprocket stops the chain's side plates clanking down as they wrap around the sprocket. If the noise bothers you or for peace of mind that the out put shaft bearing isn't an issue, simply swap it out for an OEM or the after market damped sprocket above (it's only 16 quid)

It wouldn't matter introducing a new sprocket at this stage of the chains life, seeing as the chain is basically brand new and not worn in yet.

Your welcome :)

'One tooth down' will also make it louder.

Let us know how get on.
