Hi all,

I've been using the tenere for 1year+ and is loving the bike very much but I'm bothered by an engine noise that i recently noticed.

In my 09'XT660Z @22000 km I started to note a metallic vibrating noise around 4200 rpm (starts around 4200 rpm and goes after 4700 rpm). Its noticeable with same intensity and pitch in any gear, moving or stopped, accelerating, decelerating or at constant engine speed.

It seems just like a loose screw that vibrates but with a higher pitch more like some sort of a vibrating whistle. All screws are tight though

The bike engine was full stock when I first notice this. I noticie this with warm/hot engine and I never rev beyond 4000 rpm with cold engine, so I never notice this with cold engine.

Most of the time the noise is there but sometimes it disappears for a few miles and then comes back.

The bike runs fine except between 4200rpm-4700rpm, at any gear, the engine(or some other possible location) is making the noise...

I get about 21-23km/ltr with Leo Vince installed...serviced regularly every 5000-7000km with loads of TLC...current mileage is 31000+km...

Thanks for looking guys...Any help is much appreciated..

Had exactly the same symptoms and only found out what it was the first time I removed the LHS radiator side cover. It was the top one of the two set screws that join the panel to the exhaust heat shield. The screw is too long and tapped against the exhaust pipe, it had actually worn away at an angle. I cut off about 7-8mm, refitted and the rattle disappeared!



Try pushing on the screw head and see if it makes contact with the exhaust with a metallic tap...

Same thing happened to me Pleiades, only I just swapped the two screws over and put the shorter one in where the long one was.

The screws in mine were (or appeared to be) the same length?? I guess when they assembled them the screws they were picked randomly from a Quality Street tin like I have in the garage!!
