TOPIC: Long drive killed engine? Carbs check out

Try a fishing line Nylon to get around the curves passages ports

Eh, the fishing line is too weak to push through, it folds upon itself.
I have several different thicknesses of line I tried nothing would push past the first curve.
Any other suggestions?
I'm gonna head out to a hardware & craft store to see if they suggest anything, too

If you can spray carb cleaner all the way thru the passageways they are clean.

I agree. I only use a guitar string to clear the pilot jets. Sometimes they are so bad you have to soak them in carb spray until you can poke the string through them. If you're careful you won't damage the jets. If they're slightly bigger they can be compensated with the air/fuel screws.

You guys think the water making it from the opening to the 3 dots is safe to say there is nothing in the way?

Those small passages are for the pilot circuit. Sounds like it's clear.

EDIT: FIXED. Wrong placement, and spring was loose by a turn so it didn't have enough force to close. Time to test on bike!

Great! I would really love to try it out, BUT
Now I have another problem...
I was putting the carbs back together, and am having issues with the choke spring. There was a topic posted about this, but the OG didn't respond with a picture of how it was set up.
The choke valves are uneven, and when moving the lever to the position where they are open, the spring does not push the other valve back.
I've tried different variations, but since it's obviously not working I guess I have it wrong?

The bike idles good now, but still dies with any throttle....
Ugh.

Just a quick thought...

Thanks, though I managed to figure that out on my own this morning

Just an update if some other poor soul is having the same issues as I:

Luck struck upon me and I made friends with a mechanic after getting his reference from someone at Advanced Auto Parts (hooray for conversations!)
Told him my issues, pointed him to this post, we began working together.
He checked out my carbs and said everything looked great and would go through and clean it just in case.

In the meantime I did in fact take my engine apart down to the pistons just for the heck of it even though this wasn't the issue, it was a carb one, but I figured might as well get in the best condition it can be.
Checked a lot of service limits, everything was in order, somehow magically put together the engine correctly (have never messed with this part of DIY before)

Got carbs back from him, same exact issue -> died with throttle
So we found a company that makes jet kits for twin kz440: 6sigma
Appreciated how they go about. Must tell them exact year, make, model, as well as if using aftermarket/custom/OE airbox/mufflers
Then in the instructions for the kit they tell you how to modify and why, etc...

So...the bike runs! I took her around the block
But the mixture is still a little off, so I'll have to get more advice from him.
I always have to crack the throttle a bit to get it to start.
Also the RPM's hang high when using the throttle and drop back down after a couple of seconds which I read indicates a LEAN mixture, but I don't know how that is possible as I just rejetted the thing some pretty huge sizes up (secondary is 72 and main is now 102.5)


I'll update again later.

Hanging revs can also occur if you are getting any air through your carb boots.

SOLVED
Just wanted to update.

Turns out the contact breaker point gap closes over time. I bought a new one a while ago because when I was doing some routine checks, the old one was bent (actually an old post of mine)
So the timing was sh*t because the gap was really close. Only one cylinder was running, and the one that was, well, it was running like crap.
Changed that to specs and oh. my. goodness.

This bike runs amazing. So part of me is happy it took me a long time to figure it out and go through all the other hard stuff. Sometimes it pays off to not check all the easy stuff first haha.
Because I rejetted the system, made that air box, cleaned the engine, checked all those fuel items, closed off vacuum leaks, cleaned the carbs good, this bike is insanely responsive.

Took it to a motorcycle mechanic who specializes in older Kawasaki's and he was surprised at how well it ran, I quote, " In my 30 years of working I have never seen this model run this well"
No bogging, no hesitations, accelerations great, even at 60mph its got jump if you need. Did a plug test, perfect color.

Very very happy...…
Now back to aesthetic items...
