I'm researching a new clutch for my 1993KZ1000P12.
Are all the KZP clutches the same?
I have seen a few odd year groupings such as "1995-2005", and wanted to make sure I was looking at the right parts.

I would avoid those "kits" and just order the OEM frictions and steels from Parzilla by part number. Just my 02> I looked them up a while back and all together they all run ~$150.00 for OEM parts.

I got the old clutch adjusted and it did well.

But in the meantime I picked up a $40 clutch kit and decided to try it out. It looks like cork material. I had to re adjust for the extra bite and It seems to hook very well, but I don't know about longevity.
For now it pulls hard and will spin the rear tire with ease.

That certainly sounds like a bargain. I just ordered 9 frictions and 8 steels from Partzilla yesterday. Oem parts. With another clutch cable frame clip it totaled ~$157.00 including 12 bucks freight. (combined the freight using the cart function)

www.partzilla.com/product/kawasaki/13088..._EAAYASAAEgKKFvD_BwE

I just hope I didn't waste a bunch of money buying the OEM parts for a clutch that can't hold up to my HP. I still think my 38 year old plates are so impregnated and heat glazed from the years of abuse, that new oem plates will handle the torque.

Yours do look pretty glazed, and I'm sure Ponce just dumped any old oil in it too. :-)

The OEM Kawasaki clutch plates will hold up just fine. They are actually better than any aftermaret clutch kit. I used the OEM ones on my well over 100HP KZ1000R clone. Did a bunch of wheelies, burnouts and drag races with it.

I recently renovated my clutch by changing out the springs, lubing the actuator and just checking the plates - the plates were all within spec.

The plates wear out with use, but the springs will also wear out with age, and most of our bikes are pretty old now. Changing the springs alone will often do the trick.

I replaced the springs about a year ago. I have also soaked the plates in citrus degreaser, (twice) scrubbed them with scotch brite and a brass wire brush trying to deglaze them and remove any moly additives / glaze and they still let go when I pour on the coals. My bike runs extremely strong, better than most, for sure. It needs a clutch that is 100%.


I did use the aftermarket Z1E springs. I don't have a spring scale to check them, but I assume they are still good. ,

Agreed, I kept my stock stuff if I ever feel like using it.
I just couldn't resist trying out a full replacement setup for $40 and free shipping.

Of the two clutch-cover gasket designs available for the J-engines, which is better and why?
:)
11061-1126 is just wide enough to cover the gasket surface.
11009-1210 fits over and around the end of the clutch basket.

Not so sure there daveo. My original gasket has survived taking the cover off twice so far, as I have no desire in trying to scrape that hard a** old gasket off of my engine. I still have the gasket I bought from Z1E when I bought the springs in 2017. I put a thin swipe of rtv on the cover after I clean it up, no leaks so far. I wonder if it will survive a 3rd time taking off the cover? :-)

I am with you on that, though doing so sooner will be easier than later, given the effects of aging. :whistle:
Wondering if the 11009-1210 gasket design may help prevent the oil from getting whipped-up and vaporized by the spinning clutch basket, which may minimize oil dissipation through the breather.

Also in agreement with others who are recommending the stock clutch components. FWIW, back in the day, the hot ticket for the KZ dragbikes were the factory stock fiber plates with the hard chromed MTC steels. I used them with no issues @ 275 HP and the Funnybike guys (425 - 450 HP) used the same combo. I know that you're dealing with a J-model motor, but the concept remains the same, I believe. Excessive slippage (= heat) will do in any combination, regardless of power output.

Any thoughts on my gasket question?

I would imagine keeping the oil from being aerated would be preferred Dave. Such is the reasoning on automatic transmission fluid levels and the the warnings not to overfill, to keep the fluid levels from being churned in the moving parts. This is to keep oil from getting aerated and the pump from cavitating (growling), and thus low line pressures, with partial clutch pack application.

Makes sense o_k
:whistle:

Image below from the KZ1100 Shaft FSM describes correct orientation when installing OEM Kawasaki friction plates.

Thanks for posting this Dave. I did not realize or notice that the plates had a orientation to follow, but it does make sense. I don't know how much difference it can make as far as clutch slippage, but it does have to make at least a little bit of difference. I plan on looking how they are orientated when I take it apart. In all of the threads I have read on rejuvenating the clutch (soaking plates in degreaser , spring pressure, etc.) , you are the first I have noticed to point this little tidbit out. Of course it helps If >I< do more research myself before jumping in with both feet and wondering why stuff doesn't work right. At least I WILL take solid advice that people point me towards. :-)

BUT, Hey! You have 6 clutch springs! I'm Jelly! LOL More, yet slightly weaker springs to go easy on the left hand. :-/ I wonder if I can adapt that setup onto my 81 J motor?


My OEM frictions and steels that I ordered from Partzilla last Sunday came yesterday. I was just opening the package and checking out what NON-counterfeit OEM clutch parts come from the dealer packaging looks like. All individually packaged and clearly marked as genuine Kawasaki parts. Unlike the eBay disclaimer that the original packaging may not be there.

I took a few pics for your viewing pleasure. :-)

9 Frictions:


Back side:


8 Steel plates:


And since I put on my SS Delkevic exhaust, my clutch cable seems to be getting scorched from the header pipe, since it runs hotter that the original double walled exhaust. I wanted an extra cable clip in hopes of keeping the clutch cable away from the header.

Maybe? Based on the following part diagrams the components appear to be quite different:

A backup clutch set



Picked up two 13088-1013 5-packs off ebay. $23.98 to my door...couldn't resist. :)

Am I reading this right? You got 10 OEM clutch frictions for $23.95 with free shipping? That is $2.39 each, delivered.

I paid ~$157.00 for the parts I pictured. You get ALL of the eBay deals Dave! LOL

I had already looked on eBay before I placed my order and did not even come close to a deal like that. All I was finding was what appeared to be counterfeit parts for about the same price that Partzilla was offering. Of course, I will pay a little more (usually freight charges) to make sure I am not buying either very old, or questionable parts.

Boom! Done deal. I ordered 2, even though I have the ones from Pricezilla sitting here.

I searched TODAY as I I was replying to your eBay geniusness (new WORD!) and the best deal I found was THIS:


May be missing the original packaging.
Is that a greasy hand print on the plate with the tag on it? The ad does say that they so kindly store the parts inside... Such is the reason I ordered from Partzilla. :-/

I don't know why this stuff doesn't pop when I search flea bay, I guess I always need to check with you first. :woohoo:
