Leon...

They are the VM 29 Mikuni, with the 3 screw top. www.jetsrus.com/carburetor/carb_mikuni_V...oded_view_parts.html

Holding off on the new set until I get the bike on the road. Enough with overengineering this thing !! I want to RIDE !

Assuming all goes well and I am riding it this summer, I will buy the flatslides this winter...whats another few hundred dollars anyway LOL.

Stock jetting is:
Main: 120
Pilot: 17.5

I live at 4400 Ft. elevation. I am thinking 122 Main, pilot I am unsure of.

I got the bike back from Steve today. Steve took good care of it, I think he was kinda sad it was leaving. I assured him I had been rehabilitated and was ready for parental responsibiity again.

I wanted to ride it down the street before the painter got here to take the bodywork away for stripes.

Battery dead... The KZ has cheated me again!! Bike has been sitting with a dry tank for about a year now, so it had some storage "blues".

Then Gary the painter arrived, so there was no time to charge the battery, we started laying tape across the bike to get a visual idea of what sort of stripe to put on and what color. It will be a shelby stripe, same color as the swingarm, running just off cenerline from fender, across the tank and onto the tail section.

I keep a binder full of all the reference stuff, the binder was at the shop with the bike; kind of a history book in case Steve had trouble figuring out something. It's like looking at baby photos... ahhh so cute . So tonight I am looking at the baby album...


Those of you who may be starting a project...keeep a binder with everything in it. The information comes in so handy EIGHT years into the build... wait it's 2013, so its now more like 9 or ten.. man time flies when you move 800 miles, or go to beautiful Baghdad for a while.

There are photos in the binder of the bike the day before I tore it down, you know the film kind..HA HAAA 2003 I did not have a digital camera, but a real nice 35mm. Ran across this photo which I think will give you an idea of how much the bike has changed.

I took a photo of the photo with my Phone camrea.

Good Advice Leon,

I recall my last KZ (Eddie Lawson replica) I am thinking it was 125 mains and 20 pilots. Problem is that bike had smoothbores 33mm, these are 29's, anyway I will start from there, and pull the carbs off about a dozen times before it is right on.

Hate jetting !!

Well...

Long time since last report. First the bike is still alive, I have not drug it down the street behind my pick-up truck. This is good.

I got it back from the shop in Reno (protective custody foster home for a year), and started it. Number 4 cylinder is not firing. I took the carbs off, and cleaned them. The needle and seat was stuck closed in #4. Put it back together, still no luck; but when the mains kick in it roars. I think the float level is too low on that carb, so the pilot is not getting fuel. more tinkering.

Meanwhile the Neighbor who owns the Gixxer I am restoring insisted on having the KZ paint "tuned'. The bike was solid orange, and graphically challenged.

"Gary" put some stripes on for me, and re-clear coated it. WOW !! The bike now has show quality paint. We got the title straightend out, so it is ready for the road.

I think I will end up with a new set of flatslides eventually but it is now riding season, which normally eats up the cash (track days and travel). Any way when it hits the mains at about half throttle it really sings, so this is a good sign.

I now owe Neighbor a ton of time, the paint is soooo nice it must have been expensive..but nobody is talking. The painter will not tell me, nor will neighbor. Gotta get more work done on the gixxer.

Here are a couple photo's of the paint.

What he said.

I like the off center stripe. I even considered that for my bike.
