Thanks for the replies. I have my last shipment of parts on it's way from the US now so I'm going to keep the bearings in for the sand blast powder coat process. The sand blaster will tape them up and seems to think it will be ok.

I gave them a bit of a tap with the old big screw driver down the tube trick but they are stuck firm. Nothing in the manual about removal. I might try again with my heat gun.
Can anyone advise me on the removal of these please?

Am presupposing that the swing-arm's inner sleeve has already been removed, so that only the needle bearings -- one needle bearing inside each end of the swing-arm -- are now remaining inside the swing-arm.

When removed, the needle bearings are usually damaged and must therefore be replaced with new needle bearings.

Removal may be done with a metal bar used as a punch to drive out the needle bearing from the opposite end of the swing arm.

Assure that the bar bangs only against the needle bearing to drive it out. And take pains to avoid damaging the interior surface of the swing-arm.

Reverse ends to drive out the other needle bearing.

On some models, the new needle bearings are "pressed" in.
Don't know for sure that it would ease installation, but could try keeping the new bearings in the freezer overnight, and attempt to install them when ice-cold (maybe they'll slip right into their positions inside the swing-arm).

If a plastic or rubber hammer is used, be certain that the bearing is perfectly aligned to enter the swing-arm. (Don't try to drive it in crooked.)

Remember to grease the bearings before completing assembly of the swing-arm.

Good Fortune!

Im also struggling with the back end on my project CSR1000. I got a GS1100 swing arm from a friend,which slots right in (needs a bit of spacing on the sides but the pivot pin is the same diameter). Im now looking for a wheel. Im waiting on a local seller to get back to me with an axle diameter for a GSXR1100/750 wheel.Unlike you, I dont have access or
the knowhow to be machining bits up to make things fit ,so Im trying to get parts that will work together.
The GSXR wheel is ,I think 5,5inch x 17inch so that would work good with the GS1100 swingarm but I need a 20mm axle.Then I can go with the GSXR wheel,sprocket carrier and brake caliper.(with a torque arm mount). All in one. Very little messing about.
Good luck with yours anyway,looks like youve got a long way to go but with that pile of parts you,ll be spoiled for choice.

The whole series !!

Here is a very interesting video I found.
While it does not help me too much it may help others.

Made in the 70's by Kawasaki to train factory techs:

A routing diagram would be awesome. After a month or so of searching for one, i winged it. lol. The harnesses off the handle bar controls were long enough to run down into the area above the horn, thats where I made those connections. The turn signal flasher I mounted just south of hte battery, by the tool tray. Main harness from the original gauges that I used (2 harnesses out of this unit) I left them behind the headlight bezel.
If you are making your own harness, you can pretty much put them where ever you want.
Here's a couple other things that I pondered on for a while...
in the first picture (1.jpeg), this is from the wiring diagram you are using, the blue box is the turn signal flasher, the black box was for hazard lights.
in the second picture (0.jpeg) this was mounted right under the fuel tank, just south of the coils. Brake Light failure box. And there is a corresponding light on the original speedo for this.

Here's a couple websites I have looked at that seem helpful for parts, some pretty good diagrams (the first one I thnk is a great source):

Well...
I have most of them figured out now. But there is a few curves. I definitely have a Z1B model 1975. The rectifier, and regulator are all wired in correctly. I am very glad to hear the bike had only one fuse.

I bought the handlebar switches, and the wiring harness from Z1 Enterprises. I would have thought they would come with a diagram but do not. I am going to keep after it labeling each wire as I go.

Hopefully Z1 Enterprises has a schematic available. Oddest part o figure out is the location of the connectors, the wiring diagram just does not tell you where they might be.

I think that blue wire going to the other side of the handlebars is for the starter lockout switch on the clutch...it's in series through several switches....kill switch, starter button, clutch switch...... Not even sure the Z1's had the clutch switch actually..... :S
