Hello folks so over the last two weeks ive had some issues with my 2010 660 tenere. I replaced my rear disc and pads as the disc was worn but nothing terrible and plenty of miles left on the pads. I also fitted a brand new Anakee 3 tyre which has served me well so i got another one.
I fitted the wheel and checked my chain tension and made sure it was all aligned i used a ruler as well as the marks on the swingarm and its bang on.

The problem i have is a weird knocking/clanking feeling when i let the bike just roll for example pulling the clutch in and coasting. I have even turned off the ignition and let it roll down a hill and i can feel something is clanking there is a thump every now and again. I checked the front sprocket nut and it was lose. Luckily the washer did its job and kept it in place.
I re tightened the nut to spec and again re checked my chain to make sure it was aligned and at the correct tension.
I have also checked my brakes are moving free and not seized up. They are not binding on the front or rear discs.
The bike has 18k miles and runs great engine wise did the valves about 3 months ago and also do oil and filter changes every 3.5k miles. It runs fine at motorway speeds and starts and stops with out any issues just this strange rumble feeling you can feel it on the pegs. I am starting to wonder if it could be a bolt a bolt lose somewhere. Ran out of things to check so i would be really grateful if anyone could give me some advice.
Any ideas whats causing it ??
Cheers
