Topic: Maui Z1 1973

I could not resist to search for circuit diagrams. Then continued to Google "Z1-900 circuit diagram + brown" searched brown white  too.

You are not alone wondering about these wires. Not only 900 the later 1000 as well.

Not an absolute answer here but it must be explained in another thread.

Here another model, might be same function. Read all, last post might be a correct answer.

Measure the voltage with power on and test various controls. Brown might be 12V as black is on a CB750?

The stock diagrams are more complete than later colored when describing CB750, maybe same with Kawasaki Z1-900?

I’ve seen where some bikes have a tail stop lamp out warning light, it may have something to do with that. I may change the headlamp over to one with a city bulb like the UK bikes got, some day.  My sealed beam was blown and I went to the parts store to get a replacement. I noticed they actually sell an LED equivalent for that sealed beam. I did not get one but that’s interesting. It was $154.

I'm glad you didn't Steve, I'm not a fan of LED lights on old bikes, they look weird.

[PeWe]

I tested LED in the rear on my K6. Did not work, bad light to plate.
Front LED H4 work fine. Very bright white make me to be noticed in traffic much better than std H4 my bike has as stock. Take less power too, around 35W.

I used a long fiber optic cable from the tail bulb to the instrument panel. Then I just melted the end of the fiber at the instruments' end and held it in place with a cheesy bracket I made. Then when the taillight was ON, I could see a little bright spot on the dashboard.

[MauiK3]

Very resourceful, I would not have thought of that.

Another dumb question
How do the two bowl vents route?
I assume the 4 overflow lines bunch up and drop over the rear of the engine to the swing area area.
Thank you all and Melekalikimaka

I can't help you there Steve, I'm building my Z1-B from parts. One of my favourite Christmas movies, keeping ol' Bing's song alive.

Yes, they run down in front of the swing arm

Yeah Bill, if I'm lucky it'll be in the 70's on Christmas Eve for our family BBQ (around 30 guests) and the same for Christmas Day at the MIL's place, hopefully not in the 90's, or higher. No pool like the Griswolds, though.

[MauiK3]

How about the bowl vents that need to go up?

[Stev-o]

Mine go slightly up, back and then tuck in behind the airbox plenum.

[MauiK3]

Thank you.

Today I made some progress. I’m splitting my time between a major front yard upgrade and the Z1.
I got oil into the forks which is easy and I learned I needed to fold the handlebars down to get the caps back on. No biggie. I had to fix a cold solder on the rear break light switch, I installed the kick starter and I filled it with oil and did a cold crank, no plugs, to see if oil pressure would come up. It took some long seconds gritting my teeth but the oil light went out! Thereafter it went out quickly. I just wish it was easy to peek under the valve cover to check the top end. Next I’ll get the exhaust system on, recheck the ignition, set up the temporary fuel and try to start it. These are nervous times.

I guess I need to get my daughter to help, the video link isn’t working.

[RAFster122s]

Nice, congrats!

[RAFster122s]

Link is working for me now

[Terry in Australia]

Looks fantastic Steve, well done!

[MauiK3]

Waiting for the air filter plenum clamps, I didn’t get the right ones. They didn’t come on the bike and I ordered the wrong part number.

[Alan F.]

That is a milestone, congratulations.

Excellent  progress so far Steve.

[MauiK3]

I noticed the tach didn't bump or anything. I guess it wasn't turning fast enough, I hope. New tach cable, I felt movement in it I think.
I worry too much.

[Alan F.]

I'd agree it probably cranking too slow for the tach to register.
