Have you checked your chain?

yeah it was fine properly adjusted.

This is going to sound stupid, but how are your brake pads? I'd check the wheel bearings as well.

And is the noise affected by engine speed or vehicle speed?

the noise is linked to engine speed, already checked pads and wheel bearings where fine. adjusted clutch to 1/8 inch of play in the lever. its got me baffled.

I am in the process of replacing my camchain. It was slapping so I bought a manual adjuster and that quietened it down but it didn't fix it. With the valve cover of and turning the motor over slowly (clockwise) by hand the exhaust cam 'kicks back' (anti-clockwise) and loses the tension that was on it. It looks like the chain is quite worn. 44000km's. My guess is that it is riding up the teeth on the crank sprocket, then snapping back into place.
The slap before adjusting was felt in my footpeg, and heard as a regular tick that varied with engine speed. After adjustment it just sounded like a loud top end but has a higher frequency buzzing that I can feel through the bars.
