Clutch time ....

Last time to the track i noticed that even when i knew the clutch was out the was not .. It would slide out like it had a slider clutch in it ... Clutch fully releasted but still slipping .. It just felt real strange ...The bike was do for an oil change so what better time to pull the clutches and have a look see ... I have 100 to 120 runs on the stock clutches and some of them were back at stock wheel base and not clutch mod .. I know i was pretty hard on them at stock wheel base ..

The outer plates and steels were really burnt , the ones on the inside looked better .. I had noticed that last time i rode the bike around town the bike was creeping with the clutch pulled all the way in so i felt like i had warped a steel ot two the last time to the track ..

I had a hell of a time getting the first two steels out so i'm sure they were warped .. The rest of the steels came out just fine .. All fiction plates were way way under the service limit ..

The 2012 clutch uses the same plates but in different locations , The very rear clutch fiber is the wide pad like the very front plate .. They place the thin pad fiber one out from the rear with a the clutch cushion , unlike the gen1 where the put the thin fiber and cushion all they way in the rear .. I have no clue why they do this , guess they have their reasons ..

Looks to me you need to use two wide pad fibers and not one wide pad fiber like the Gen 1
Nobody is listing a clutch for the ZX14R yet.. Track king and Drag Pack clutches only offer 2006 to 2011 .. I think Wee changed his , maybe Wee can tell us what he used ? Wee you out there , please weight in before i order clutches ..

Smokin, I changed because I thought I hurt it running without Brocks shims/clutch mod, lots of runs without it, I don't remember the stack height, I know it had wear so I replaced it , most of the fibers were good, some had a bit of wear, I went back with a 09 OEM clutch I had from a couple of years ago.

My steels came out easy and you know I leave at 7000-7500 rpm range, being at almost 70" wheelbase allows me to get out on the clutch pretty fast so it's not like slipping it at short wheelbase to control wheelies.

I've never tried an aftermarket clutch, I like the OEM and it works well for me, so that's what I will use in the future...

So Wee, is there anything significant with the '09 vs. other years?

Not that I know of, like Smokin said, on the 14r the judder spring is located in a few plates unlike the Gen 1.

Mine never did this before this last trip to the track .. It has to be the first two steels i pulled out causing it ... I had hell getting them out .. I have never seen a set this discolored in a zx14 before .. The first three plates were black ..

I guess no matter how much things change, clutch problem stay the same. on the older models You could take the oil cap off and look at the clutch if the installed heights were right, the outer edge of the clutch basket would be even with where the pressure plate dropped over. This was always a quick examination of how much clutch wear You had. not so much that the clutch was down , but that you were losing spring pressure because of it. And that made things worse. I haven't looked at wee bike to see if that's the same? a quick fix would be add shams to the Springs to make up the difference The clutch was down. obviously this would not fix warped steels.

yes, that is exactly right. Those two arrow should line up even. looks like you're down about 30 thousandths. That's not bad. It just means you've lost that much spring pressure. As long as the clutch is still working good That's not a problem, but if the clutch feels like it's week. You can shim the Springs and you are good to go, unless the steels or bent. and that's easy to tell when the steels are in good shape, and you pull in on the clutch There is no drag, but when they are bent the bike wants to pull a little bit even with the clutch in. I can always tell when mine are bent when you go up to the line and bring it up on RPMs. The bike will try to pull even with the clutch in. When they or in good shape There is only a small amount you have to let out on the clutch for the bike to leave.

Thanks, that will save me some time not having to pull out the clutch and measure it.
