Better Than Nothing---The rebirth of a Superbike.

Been cleaning up in my work area. I gathered up all the plugs I have had in my KZ since I started it up with fresh motor. It was STONE RICH when I fired it up for the first time as you can see from the first plug on the left. As I dropped the jets, and changed to different needles, and air correction jets you can see how the plug color started to get lighter, and lighter as I got closer to being right on on the jetting. I started running out of new plugs so I started just changing one plug instead of all four between jet changes.!!! I hate living on a budget. I had my CR's off and on my bike something like 15 times!!!! The very last plug on the right has about 75 miles on it at high speeds. I did a plug chop on that last plug too!!! I think I am pretty close by the color. I am leaving it for now!!!!

Been getting bored not be able to ride anymore, plus its starting to get a little cooler here in Az today. I found me a new place to buy titanium fasteners. They actually have gone down in price since the last time I bough some years ago. Since I sold one of my diecast cars, I bought me some fancy new nuts and bolts!!!!

In just seven bolts and three nuts I saved 5.90 ounces over the steel fasteners I replaced!!


They sure are pretty!!!


I also replaced the stock steel steering stem bolt with a aluminum one from Yoshimura. That alone saved 1.1 ounces.


Unlike spending my extra cash sitting in a bar, or packing my nose with cocaine, I got something to show for it at the end of the day.


Sure are pretty to look at!!!


Going to sell some more diecast cars, and get some more of those shiny objects for my Kz!!

FOXY: :evil:

Where did you find the Yoshimura Steering Stem Bolt? I can't find any place that offers a Z1/KZ bolt. Is that one intended for a newer model? Any idea which one?

Yes Sir, like Scirocco posted. The one foe the 250 Ninja has the same diameter and thread pitch as the KZ1000.

It bolts right up.

Someone out there makes a titanium copy of that same bolt. I just couldn't find it anywhere to order it!!!!

I sold some blood at a couple of blood banks, so I ordered a shit load more titanium fasteners for my KZ!!!

Do you have all the jet/needle settings for each respective spark plug? I'm setting up mine now and have an extremely rich setup. Thanks in advance!

I have notes on my jetting changes, but I can't match the specs to each plug in photo. I will give you some info on my motor, and what I ended up with. Mind you I am at 5,000 feet altitude here in Arizona. The jetting changed dramatically from what I ran back in Chicagoland with same basic motor. I have CR33's on my bike. Motor has tons of compression, .440 lift and 284 degrees of duration cams, and is 1105cc's. I always ran my motors on leaded 105 to leaded 110 race fuel.

I tried 62, and 65 slow jets. Mains were from 125 to 120. Air correction jets between 180 to 200. I tried YY7 and YY8 needles.

I run the med length velocity stacks. Never played with air filters. You are on your own on that.

What I ended up with out here was 65 slow jets, 122 mains, 190 air correction jets, and YY8 needle 5th notch. air screw 1 turn

I ran 128 to 130 mains back in Chicago Slow was the same, but needle was YY7.

Keihin CR's are real picky carbs. When I sych mine, I use a .022 piece of wire on the front edge of slide. Never had a motor that had a steady enough vacume to use gauges or sticks!!! Everybody I know with CR's does the wire sych on their carbs. And always drain the fuel out of your carbs if it is going to sit for more than a week or so. Watch the o-ring around the needle seat too!!!

ALWAYS RUN A PUSH/PULL THROTTLE WITH CR CARBS TOO!!!!!

Hope this helps you.

As soon as I get my last order of titanium fasteners, and the hollow front axle for my KZ1000 Superbike, I am calling its restoration complete. Due to health reasons, its looks like my riding days are on hold. This bike is going to be a fixture in my living room from now on. Hope my landlord don't go through the roof. Here is what the final version of my Kz1000 looks like. Its been 39 years since I started building this bike. And this past year marked the first time in 32 years that it has been all together, and running!!!
