Rocket three primary drive noise

[Tav]

Hi all continuing on with my rocket three. Tappets now sorted. Engine runs really well. But one he'll of knock on tick over. Dissappears as Engine speed increases. Noise is coming from primary drive. The triplex chain was well past it so replaced. Noise still present. So far I've stripped it as far as the sprocket and apart from the clutch seal being the wrong way round. Nothing definite located.open to any ideas please thanks in advance

When you adjusted the tensioner did you pre-load the chain by pushing on down on the kickstart?

[Tav]

Hi there no I didn't do that. But I will do so after reassemble. The clutch hub was on closer inspection quite worn. New one ordered. I will let you all know the outcome and try to post some photos.  Thank you for the advice

dont forget to replace the shock absorber rubbers

Hi yes the cush drive rubbers were again badly worn and are being replaced as a matter of course. I think it worthwhile whilst it's stripped down. Thanks for the advice  appreciate it
