With 37,000 km on it you SHOULD have at least looked at the cam chain tensioner by now.
Do you do your own work on the bike? Are you comfortable opening up the bike and working on it yourself? Do you have a place to work on it, inside? Some guys have to park on the street and can't do much themselves.
To get the clutch cover off you will need to drain the oil and take off the footpeg and exaust. Then you NEED TO MAKE A PATTERN OUT OF CARDBOARD TO PUT THE BOLTS IN SO YOU DON'T MIX THEM UP, OR LOSE THEM!
As you can tell by now taking off the clutch cover is NOT a''first time I ever worked on anything'' job. How much experince do you have working on cars, and bikes? Where are you? There might be a member nearby that could help.
If you get it off, post a picture of the open side so we can look at it, a pic is worth a 1k words.
I do just a simple works on my bike by myself. Don't have a place to work on it, I Live in the old city centre, and park my bike in passage to be protected from rain.. Location Herceg Novi, Montenegro (near Croatia).
My mechanists is only available during weekends, so I will have to wait until next weekend cause he is fully booked now.
Additional info: 2 months before I have changed my tires, front and rear. After that guy in the workshop didn't level properly rear tire and the PULLEY was scratched pulley cover. After that I levered the rear tire, check the tension of the belt and have to remove the pulley cover because it was making a noise when the bike is rolling in neutral. Don't know if this can be connected with this problem...
