Reply To: Valve clearance, camshaft, camshaft tensioner – a problem or a serious fault?
This may sound stupid, but i trust you already did that but can you tell us what compression is on each cylinder?
As you follow the service manual , i won’t need to explain how to do it but if you get stuck , just reply here again.
Also, when the noise comes from engine –> Get a screw driver and poke the tensioner –> put your ear on the other end of the screwdriver — > ask someone to rev the bike a little bit, so see if you hear any abnormal/weird tensioner noises and cam chain slapping hard ?
Did also check each camshaft is correct ? and checked cam-shaft bearings are OK? – Sometimes previous owner puts a “Rear EX” camshaft in to Front Cylinder and problems start
