Hi everyone,

Got back from a run over Christmas and picked up a dodgy noise when on the revs.

Any ideas? [video]https://www.facebook.com/motmemes/videos/308468466461167/[/video]

I listened to the clip and it's way too short to even get an idea of what's happening with the RPMs or the rest of the bike. A longer sound clip or video, with idle speed and then some throttle action would put the noise into context better.

Sounds like something is loose.
take the left side case off and make sure everything is tight and look for rubbing marks on the inside of the cover.
try and listen to the engine close and see if you can spot where its coming from.
rev the engine with the clutch lever held in and see if it goes away or is worse, that will tell you it could be the clutch basket is loose.

If you have a long screwdriver, you can hold the handle to your ear and put the tip on different parts of the engine to see if you can pinpoint the area where it's the loudest. Sort of like a mechanic's stethoscope. I listened a few times and was wondering if it has something to do with the cam chain guides or tensioner. If you can isolate the area, maybe we can narrow down the cause before you take too much stuff off and lose the ability to run it and listen.

The noise seems to be coming from the left hand side, behind the cover you take off to clean the gear lever. Gonna take it apart and check for loose bits, marks etc as shakennstirred mentioned. Fingers crossed.

Noise was the same with clutch in and out...

Have you checked the exhaust pipe collars? The bolts tend to work loose over time.
