R6 Clutch Rumble/grinding/annoying bloody noise!!

Hello,

Read a lot of online posts about this already but cant really get a definitive answer, so hoping someone can steer me in the right direction. Current situation is below:

- 2002 Yamaha R6 with 25,000 miles on.
- Bike previously fine, well kept , oil changed very recently, passed MOT earlier this year.
- Bike now have a noise that is at the same speed as the engine and can almost be felt through the foot pegs, the noise goes away when i disengage the clutch.
- Had a second rider confirm noise (my dad) who has been riding bikes a long long time and also suspects clutch.
- If i was to describe the noise in writing it would be like bom ba dum ba dum ba dum ba dum (nah im joking Smile

)

So....... what am i going to do about it, i have the haynes manual out, im scouring the internet, its currently on the side stand and ready to have the fairings removed. I am no mechanic but i can follow instructions in a Haynes manual like nobodies business Smile

, past experience on bikes only goes to changing chain & sprocket, changing oil, swapping out spark plugs, checking carbs . If i need to remove the engine or do any serious work then the bike is going (paid £2200 for it, dont think i will lose to much of my money)

Going to start with the below:

- Check front sprocket on chain and ensure its actually properly in place
- I dont really want to put i am thinking of inspecting the clutch ( do i have to drain all the engine oil? damn it, i have good oil in there and i aint pouring it back in!!)

So anyone else have any suggestions? further troubleshooting i can do before i take drastic action, its sunday today and ill probably get a chance to look at it in a few days time when my wife and child allow Smile

Thanks in advance for any help

collapsed thrust bearing?

Old R6's use a pull style clutch/rack and pinion type thing, with a bearing behind it to take the stress when it's disengaged. This.

And is the clutch bearing the same as the thrust bearing? ( I will goggle it also so not asking you to do the work for me lol) the thrust bearing, after reading up sounds pretty spot on. But what exactly is a clutch bearing? Is just a generic name?

Had a similar thing on my ER6, it was just a loose chain, knackered sprockets and tight spots on the chain. C&S swap I'd do first, it's easy, not expensive and you've done it before.

I felt it through the foot pegs and disappeared with the clutch in.

Did you check out the thrust bearing? No. 7 in this picture. That's your most likely culprit.

If it's the bearing surely it would make the noise in neutral too?

If it does it in neutral when stationary that can run out anything to do with the wheels/chain/sprockets/tyres.

Thanks for the reply. I think this gives me a clear direction in which to go. I'll replace the bearing and see how it goes, I'm wanting to sell the bike really so hoping I can get away with £0 haha although it's looking unlikely.
