Wanted 1980 Kawa Kz1000 Z1 wiring diagram

I need a wiring diagram that I can read a lot better than the one in the back of the manual. If anyone has a factory repair manual or send me a web site that I can download. Thanks for the help.

That sucks, there's none in the file base .

Which 1980 KZ1000 model doesn't have its wiring diagram included in the FILEBASE?





Good Fortune!

I am looking for the 1980 Kawa KZ1000G Z1 Classic Fuel Injection Manual or wiring diagram. Thanks

The wiring diagram in the back of the manual for the G model is terrible, but unfortunately, there is no other available that I am aware of. However, when I get home this evening, I'll check to see if there is a diagram for the Z1000H model...which was the euro equivalent of the North American G model. If the diagram is decent, I'll post it.

Attempting to upload the Z1000H wiring diagram (in two parts) to the filebase (and under KZ1000G1 as there is no Z1000H as a valid model).

A bit late, but I finally got the color wiring diagrams for the 1980 G model posted (used the diagrams of the euro H model which should be fairly similar). Look under the KZ1000G1 1980 filebase.

Thanks for the help.

Are you still using the FI system? www.redlinecycle.com has some of the parts.

Also read this about a switch problem inside the airfilter box:


1980 KZ 1000 G1 (Z1 Classic)
I took this from the www.kzrider website.

below is a description with autos and part numbers for this throttle switch. ONLY COST $80.

This little switch has *profound* affects on the usability of the bike. Only 1 side of the 2-pole switch was intermittently bad, and it basically made the bike UNUSABLE.

I found the switch today at O'Reilly Auto Parts store here in Silicon Valley -- they used the matching autos to look it up in the O'Reilly computer in the store (using 'Kawasaki' or the Kaw part number was *not* useful, it had to be a car with the year/model or a part number for the switch).

The local O'Reilly store today looked it up for the 1979 Datsun 280zx and they HAD ONE IN STOCK. Put it on the bike, I'm gone on a 45-minute ride around the Valley!
NARY A HICKUP. Bike is fiiiiiine.

So for anyone else with this one-year-only Kz1000 "Z1 Classic", here are a few ways to find this switch:

1) 1979 Datsun 280zx "Throttle Valve Switch"

2) 1980 Datsun 200sx, find it at
Remartautoparts.com, with Remart part # TH114

3) "BECK ARNLEY 158-0492 Fuel Injector Throttle Switch" (NOTE: the 158-0492 is a 'master' part number apparently that most Auto parts stores can use to find all the vendors of this switch)

4) 1986 Nissan 300ZX Turbo "Throttle Position Sensor",
the part is mfg. by 'Nile'

If I were you, I'd buy one to have on hand if your bike acts up like this rider's did.

If you end up needing a fuel pressure regulator, Google "pogue machine Oklahoma City" Call them. You'll either get Sid or Butch on the phone. Get one of their adjustable regulators. You probably won't have to even touch it after bolting it on.

You guys are doing a good job diagnosing this bike. If you can afford it, get the injectors cleaned & balanced too.

FYI, the filter will never be full when the bike is running. Generally 1/2 - 3/4.

Check all the vacuum hoses over carefully. That rubber is pretty old now

Okay thanks Larry, yes these guys have helped me take the bike from:
- not running for 10 years
- running like a new bike
It was a long road but the rewards in learning and riding have been great. I have to say without Motor Head this bike would probably have carbs on it right now. Let me say the prior owner had really given up on ever getting this going again, it is remarkable that apparently the bike has turned a corner for now. I am open to the possibility of the 'rough running' symptoms returning but right now it is running incredibly well.

Thanks for the pointer to the fuel regulator -- that sounds like a good feature to be adjustable and will check it out if my regulator gets ornery.

I was planning to get the injectors cleaned but this bike is close to pulling up the front end on a hand full of throttle so for now I'm going to ride it. However I will check the hoses which is something I have not done. Most of the turnaround effort on this bike has been electrical in nature.

I don't see a wiring diagram for the 1980 B4 either. :S

B3 may be very similar, but haven't compared side-by-side.
