Lucien, all the wire connectors are available on E-Bay. Search for '2.8mm Japanese wire terminals' .

I forget the website, but I've ordered new electrical terminals before. I just haven't felt like waiting for the lead time on shipping, usually, especially if it's something minor like the fuel sender. Still, I really should just get a big box of miscellaneous connectors.

Decided to go to Gilmore, and I'm glad I did. I needed to get out of the house for a bit. No swap meet, but attendance for the show was surprisingly high for all that's going on this year. There were a few clusters of people outdoors, but overall maintaining 6 ft. spacing wasn't too hard.

As far as MY KZ goes, I've got a (metal) fuel filter coming in the mail. In the meantime, I really want to take a look at the idle circuit passages and brass for cylinder 3. EVERY indication is that I've got some kind of clog in the transition ports, or something otherwise messed up. I forget if I replaced the mixture screw, but I have extras.

And finally, for someone wanting a project, somebody in one of my Facebook groups in Connecticut posted a mostly complete KZ1300 project for $1000. I almost snagged it just for the spare parts....

Lucien, I keep that kind of stuff 'in stock' just in case I need them in a hurry.

Yeah, I'll probably buy me a box. Between the fuel sender and the fun with the ignition pickups, I've been having to fix them more than I've expected. Oh well. May as well do these things properly.

Speaking of a 50 page thread, I've went back and noticed some fun things pertaining to how long I've owned this bike. Take, for example, the ignition pickups. Some darn fool replaced one of the pickups, and (and the time) I though soldered and spliced them into the wiring harness. Looking back? Turns out that fool was ME! (the pickup was still replaced by the PO- he'd just used wire nuts).

As for my running issues- I'm going to do some picking. I've already pulled the carbs (again) to confirm the idle transition ports are clear (a known issue- they are), and that I'd replaced the idle mix screw for cylinder 3 (I have). But I've got a theory. I'm curious if I have a header or exhaust leak, enough to explain those pops out of the left muffler. Is it a perfect explanation? No. But I'm running out of ideas. (Really all that's left is "This bike is haunted".)

Here's an off the wall question. Did/do they ever offer aftermarket carbs for this? Like the best carbs for the 900/1000 are the Mikuni 29mm Smoothbores. Anything ever offered for the big 6?

A Question.
Did you perform a cylinder compression test on all 6 cylinders after reassembling the engine

Nothing I've ever seen aftermarket. I've seen maybe 1 or 2 custom builds that have run 6 individual carbs, but nothing with any kind of production run, and never for any performance gain. The stock twin barrel carbs have their design quirks, but nothing I've seen to consider them particularly unreliable, or even that finicky.

Just for fun I'll get another full engine compression test done while I've got the carbs off. I have got some decent milage on it since the last test, so I'm curious what the current numbers are.

But I never figured too much compression would be a problem. Sure, 3 is higher than the others, but it's right in the middle of where the compression is supposed to be. If anything, 1,2,4, and 5 are a bit low.

And yet.... technically it IS more project than functional transportation at this point lolol

(I DID find that, for whatever reason, my center carb float setting is both insanely high, and probably leaking. Not sure how it happened, but I've got spare float valves aplenty, so I'll see what that does sometime this week.)

Every time you add to your kiwi post, it reminds me of the fella I met at a motel in Oregon.
Us in our car and him, polishing his gorgeous, stock shiney Black kz1300 outside his room. He was 500 miles from home and was exploring the local ghost towns. Very impressive to stand next the a we’ll sorted running, reving 1300.

In an annoying turn of events, it seems that maybe at one point I had the right idea, but corrected it in the wrong way. Recently I thought my left exhaust pop may have been a header leak, so I went ahead and replaced the gasket on cylinder 3 (my usual problem child). After no change, I realized that I heard a slight ticking sound from the left corner of the engine. In all honesty I'd noticed it before, but it was close enough to "valve train noise" I gave it a pass.

Well, after throwing the carbs back on after replacing an apparently leaking float valve, I decided to have some fun and try the "screwdriver as stethoscope" method, and sure enough, there's a pretty consistent ticking noise coming from the left side of the engine. Very similar to the description of an exhaust leak.

Specifically cylinder...1. :IDTS:

Thankfully I've got all the parts to replace the gasket, and if it DOES eliminate the exhaust pop, everything else is just a straight tuning issue. But looks like I'm prying the radiator off again....

Well, I got SOMETHING figured out. Exhibit A: Cylinder 1 header gasket.

Image

If nothing else, I'm sure this explains my persistent (as in, "since I've owned the bike") popping out the left side exhaust, both at throttle and while slowing down.

Will it solve all my problems? Probably not. Will I have to go back in and address this again? Maybe. The chrome on the end of the headers is folded over the edge rim, and this almost looks like gas escaped between the ridges that resulted. I may have to get back in there and dress the header edge a bit if my new gaskets don't "take", but at least I know what to look for.
