Evening I noticed recently that my bike appeared to be knocking when cold. I have had a quick look and noticed that smoke was coming out of one side of the power valves between the barrels and the noise appeared to be coming from the valves. I got a long screwdriver and pushed on the power valve connector and the noise stopped. This is as far as I have got and would appreciate any advice or comments any YPVS experts may have. Is it likely that the power valve bushes require replacement?

Checked the linkage bolts and the 2 moon shaped bush locators are tight?

Bushes will be knackered and may have worn the barrel tunnel

Thanks appreciate the advice, looks like I better get the socket set out. If the barrels are worn can they be repaired?
