Gday all, My bike has a tapping noise that increases in frequency as RPMs increase and remains audible throughout the rev range. The noise is present in neutral or gear, clutch in or out and stops as soon as the engine is switched off (tested this going down the driveway, in gear). Have already checked the valves twice so this shouldn't be the cause. I'm just wondering how you inspect a cam chain for damage? I've checked the cam chain tensioner and according to the manual it's operating fine, the CCT slipper and cam chain guides both look fine, no wear or damage. I can't remove the entire cam chain to take a look (still attached to the crankshaft sprocket) so I was wondering how can I tell if it is the cam chain that is causing the problem?
