I'm going to be tearing into the clutch soon enough but wanted to see if anyone might have some insight before I do. This is on my 2005 ZX6R (636) track bike with 26,351 miles on it. Most of those were street before it became my track whore this past February. Last couple track weekends I noticed that my clutch was chattering like a Ducati at idle, letting the bike warm up before going out. Bike rides fine, no clutch slipping or grabbing or anything unusual. The chatter would greatly lessen after a session and everything was nice and hot but still be slightly noticeable. Pulling the clutch lever in and the chatter would stop. Taking up the slack in the clutch lever but not pulling it in and you could feel the chatter thru the clutch lever. I'm thinking the clutch is maybe dying or I might need to tighten the springs or something, won't really know until I take the cover off. Any thoughts? Anyone ever see something similar?

Could be the clutch basket is worn enough that the plates have some extra play and are banging around between the basket "fingers"...

I've had others say it could be the rivets holding the gear to the basket might have slop in them. Either way, things are leaning more and more towards the possibility of a new clutch basket along with fibers and plates.

If you need to replace parts on your sportbike there are many worse options than the clutch and clutch basket. I've got 30K miles on my 07 RR and I'm thinking of replacing the clutch as preventative maintenance. It still seems to operate fine to me, but with 30K miles and a number of trackdays, I'm wondering how long it will last...

clutches are not too bad to replace (or too expensive) yourself. just one of those things where you really want to make sure you follow the directions.... good time to upgrade to a slipper  _________________  Ἢ τὰν ἢ ἐπὶ τᾶς www.WickedRacing.com - Go Fast Parts & Gear for Riders and Their Motorcycles PM me for "TrackWhore" special discounts

I've used the shit out of it too  Probably wait until the first of the year to rip into it since X-mas is going to take up funds that could other wise be directed to the bike.

Like I said, clutch seems fine when I'm riding but I think it's time to take a look at it and do the PM stuff before it lets go while I'm riding, potentially doing more extreme damage.

My r1's clutch is still the original with 38K miles on it, i've thought about replacing it as maintenance too but if it's not broke...dont' fix it I say

I usually live by the "if it's not broke, don't fix it" moto as well. I would think that if your R1 clutch is still good after 38K that there's a good chance my RR clutch still has some life left. I'd think the R1 is harder on the clutch than my 600, although, I'm sure I have to shift more. I don't have a slipper and I don't rev-match really at all on down-shifts. I just bang down-shifts and modulate the clutch a bit (with the throttle closed) to keep the rear wheel from hopping/sliding. I'd just hate to have my clutch start to slip during a trackday...

I'm going to ask a question: What oil are you using?? The reason I ask is I own a Kawi and have owned a few (ask the guys on the board here...  ) all of them being the ZX-10 both 1st and 2nd Gen. I noticed if they had synthetic in it, they were rattling....as soon as I switched from syn to regular oil....no noise. It's just a suggestion and a cheap one to check before tearing into it. If you want, I can ask my buddy Will who is the mechanic for the California Superbike School, all the school bikes are 05-06 ZX-6's.....he would know for sure.
