Any issue with the Yamaha Tensioner I have come across are usually rust in the tensioner from lack of use and lack of oil changes. It could be as simple as a perished rubber allowing metal on metal or a loose dowel in a hole, the list is endless. Are all the tank mount intact and bolts tight. I came across some time ago where the owner of a Fireblade was being driven demented by a metallic buzzzing sound which was a a bolt dropped by a mechanic on to the exhaust which was jammed in between two downpipes
I'm even more confused now to be honest.
After work earlier I start the bike up and there is a mild cam chain rattle going on straight away from cold. I totally know this noise and I'm very familiar with it.
Then a mile or so down the road the buzzing starts, but AS WELL as the cam chain rattle.
The thing is the cam chain noise is a fairly consistent speed, but the buzzing sounds more intense and does increase or decrease with engine revs.
But surely you can't have two noises at different speeds from one moving part, which is why I'm starting to doubt it is the cam chain at all?
