Okay, I know I've posted before regards this but it is still bugging me (on a 2006 Daytona 955i with 3200 miles on the clock)....

Does anyone notice on their bikes, what I would call a bearing rumble from the clutch release bearing when disengaging the clutch, ie; clutch in (no noise), clucth out in or out of gear (not overly loud but noticable rumble/chattering). I've been told before that I am a little paranoid when it comes to noises, but I'm sure this isn't totally normal. Bike runs perfectly, no jumping out of gear, no false nuetral, no slipping clutch. The dealer I bought it from says it is completely normal and should be expected.

Any feedback would be gratefully recieved.

Cheers, and a Happy New Year,
Si

Relax mate, imagine you have a lot of metal plates all with a little gap between them held in a basket by tabs that stick outwards into the edge of said basket and the whole thing is on a spinning shaft only partially submeged in oil and stood on its end, put it into an engine with mild vibration a load of pistons flying up and down forced by explosions every point somthing of a second. Well you would expect them plates to rattle a bit wouldnt you, thats all it is, have you ever heard a Ducati dry clutch it sounds like the whole tea set has been thrown off a cliff. I would worry if on accelerating your revs rise but your speed don't or its snatching and juddering when you move off, clutches make noise its just a fact of life. :-D

What you are hearing is the equivalent of a throw out bearing in your car. It floats around on the outside of the clutch basket until you pull in the clutch which depresses it and takes out all the clearance necessary to not slightly engage the clutch when it's not being depressed. Relax a little 'rattling around' is normal. My old CB900F does it too and it's been doing it since 1981!

Sometimes you won't hear them when the bike is really new. Probably because everything in the engine is a bit tight and needs to loosen up a bit anyway, but chances are you don't hear it when new because your to worried about your first scratch on it and paying more attention on not doing something stupid on your new ride! Now that you have a few more mile on your baby and feeling a bit more comfortable you are getting more tuned in to all the little noises you didn't hear before, even though they were probably there anyway. It fine, a few more miles and you'll soon tune it out because you will know it's normal.

Thanks guys, I guess when you hear it from fellow Triumph enthusiasts it tends to make a lot more sense. Now I've got the new race can on and tune patched in it does tend to drown out any noises, so I guess I'll start enjoying it a little moree and stop being paranoid!! :razz:

Cheers again :)
