kz900 strange engine noise

Does anyone know what is purpose of this part 92043-109 PIN
on output shaft. I mark it with blue colour dot on first picture.
It seems that someone put transmission from kz1000a4 in my engine. I cant see that part anywhere on my transmission.
The diagram of kz1000a4 does not show this part. Also on my shaft, I have this type of nut and washer as indicated with red dots on secon picture.
Help pls!

Complete clutch is probably from kz1000e2 shaft. Same as on this picture.
And everything works just fine. Amazing :dry:

Live from the place of ongoings!

Does anyone know what is purpose of this part 92043-109 PIN
on output shaft of transmission?
My shaft is from Mk2 model and it has no hole for this pin.

While I am waiting for my parts to come I played little with my dremel tool.

And this is what it came

Shake, rattle & roll is the norm for the basket springs in those motors. There is an upgrade kit APE sells with heavy springs, new backing plate and rivets that you weld. Might be worth the piece of mind you'd get from it...

Generally though, those baskets work just fine unless you're severely abusing it at the drag strip every weekend. Scarey to hold that thing in your hand and listen to that rattle but in all honesty, they are solid baskets.

Case looks repairable. A good welder shold be able to handle that.If you end up needing them. They're all over ebay. Look under dragbike. Prices are way down on that sort of thing.

It's your nickle but IMO, you're best bet is tear everything down and go through it carefully. Check your transmission bearings out as well.

If it turns out you had oil problem to top end and cams are worn...holler...I've got several sets of stockers. You can have a set for free if you need them...

This is what I found when I opened it.

Cam chain is rusted on one place. Maybe its been knocking. Also, I found a marks from camchain on crankshaft cap :ohmy:

Also, I found a circlip from shift rod is fell of

And my transmission ball bearings are worn out

I dont know what of this, could make a noise like my zed was makeing?

WHoa... First image, top idler assembly....

You found the bolts raised as depicted in the image?:blink:

If holds true, check the inside of the valve cover for markings.....

No, I loose that bolts There are no markings inside valve cover.

Transmission gears are like new but bearings are worn.
So I bought all bearings inside engine.
- 2 ball bearings for input and output shaft
- 2 needle bearings with bushings for input and output shaft
- 1 needle bearing with bushing for clutch basket
- 1 needle bearing for starter clutch gear
- output shaft
- starter clutch assembly
...
All of this parts I found at www.kawasakinosparts.com/index.php
Prices there, are lowest I could find.

Also I bought clutch basket rebuild kit, springs and rivets, from Ape. Does anyone knew procedure for rebuilding cluth basket? I thought that I saw some posts with pictures of that on this forum, but I cant find it now.

Transmission is done.

I am just waiting ape kit to rebuild clutch basket and engine can be assembled.

Looks like you're covering all the bases pretty well.

Blow out all the oil passages real well. Don't forget the tranny oil passages.

Loktite the oilpump mount bolts.

I received APE clutch basket kit and already disassemble
clutch basket. Tomorrow I will take it to the machine shop
to expand rivet holes and to press rivets in. I am only concerned about this heavy duty springs. Original springs
are 3*thiner and 3*thicker and this springs in APE kit are
all thicker. I dont know how it will be shown in practice
Whether the clutch would have strong shocks or something
else??
Is there anyone on the forum to have some experience with heavy duty clutch?

Clutch basket is done. I didnt weld it, just put new rivets. Heavy duty springs are longer for 0.5mm and there is no play in those springs anymore
