Problems; Where to begin '81 KZ750 LTD

Okay I'll go out and take some more pictures today. My owners manual just shipped this morning, so I've got some more waiting to do. I've just been focusing on cosmetic fixes over the past few days, painting this and that and getting rust off of stuff. I'll take some pictures of different things again, hopefully I'll get something you guys can go off of.

I was bummed when I realized how much money this bike was costing me but after all the painting and polishing, then the tear down for new parts, then I fired her up and went on that first ride, all that didn't matter anymore. Bossie the Kaw was back and this time she'll be better than new. :woohoo:

Hey Swest, NOBODY CARES!!! Lol just kidding, I'm just jealous. I sort of feel like that's how mine will be. I have the money to invest a little at a time now, but I cannot afford a "NEW" bike, or a used running one for that matter, so why not redo it all? New wiring and all, at least then I'll have peace of mind knowing that those items I replace won't go bad in the near future.

I have a question though, I'm looking getting new left and right side controls for my handlebars, since mine don't work (No idea why, temp turn signals were on here when I got it.) Is the brake supposed to be on the left or right? Mine is on the right, with the clutch being on the left. However, this new left side control contains the "brake light switch?"?? But there is no spot for this on my clutch, just my brake. Here is the link, am I crazy? or is this supposed to be on the right?

That switch prevents the starter from working if the lever isn't pulled in. I'd bypass it. Open up the controls and spray carb cleaner or cleaner you find at radio shack. That stuff has lube in it. I use spray lithium grease once they are clean. Also check and clean the ignition switch the same way. If the back is loose you can tighten it down with a punch at the crimps. There should be three of them.
It don't matter if anyone cares, it's my butt on the bike and it cares a lot. :woohoo:

BTW, I started cleaning and painting a year and a half before I had any money to put into it. Kept me sane.

heres a pic of my set-up on a 1983 KZ750 LTD K wires to battery. As relates to image 3 (see quote below) the yellow and black wire can be seen on the neg side along with a larger wire. The pos terminal only has one wire . The front of the bike is to the left. I can take a better pic later.

Left side coil --- 2-3 spark plug wires --- red & green igniter wires.

Image 2. probably the red power wire from the voltage regulator & is bullet connected to a red/white wire that goes to the starter solenoid pos (+). you'll have to trace the wires to verify.

Image 3. yellow/black is typically a ground wire, but I can't tell where it terminates.
Maybe the ring connector should be connected at the battery neg (-). ???

Image 4. could be for the low fuel switch from the fuel tank.

Image 5. The big connector is probably the ignition switch. the green should mate with green --- maybe the tachometer. There should be a blue/white accessory terminal (typically unused) & a black/yellow accessory ground terminal (also typically unused). Plus other stuff you'll have to figure out. speedo & pilot box lights. handlebar control switches. clutch switch. brake light switch.

Image 6. The red connector may be something to do with the turn signal canceling unit or the reserve light device. ???

Image 7. shows the accessory fuse box w the black/white accessory terminal.
There's also a blue/white accessory lead that terminates at the headlight bucket.

A 750 Twin is going to be different from a 750-4.

Thank you for pointing that out. It did not occur to me :blush:

The wire colors & much of the wiring will be pretty much the same, but the battery & electro stuff orientation are probably different.

Early on I bought a nice new 750 CSR tank for my 650-CSR --- it didn't fit as the Twin has a rear tab & the 650 uses a bolt to affix it to the frame. doh.

Well everyone, its been awhile since I've been on here so I thought I'd give everyone an update. My manual was delivered a few weeks after I ordered it. It took me another couple of weeks to work up the courage to attempt to fix the wiring issues I was having. So I sat down with the manual and a 6 pack of Sammy Adams and began to follow all of my wiring to make sure everything was where it was supposed to be. About 20 minutes in I started to notice differences in the wiring that was coming and going from my starter relay compared to what the owners manual showed. So I mimicked what I saw in the manual and presto! She's ruinning again. I put new spark plugs in also, just to start fresh. So once that was fixed, I became much more comfortable working on the bike and I've fixed and upgraded a lot of other things since then.

I just wanted to thank everyone who encouraged me not to give up and just buy the manual (as much as I did not want to because I didn't think I had a chance in hell at fixing the problem myself). All your help is very much appreciated. I'll add a few pictures when I go outside in a minute. I just wanted to thank everyone before it slipped my mind. I would've sold the bike for next to nothing if it hadn't been for this forum and the users of it. Again, thank you all that contributed. When I got off the bike the first time after I fixed it all and got it street legal, I hadn't smiled that big since I touched American soil after my Iraq deployment haha :lol:

I'm glad to see you got it sorted out! The manual really is worth its weight in gold. Ed

Excellent news!!! Those 750 LTDs are built solid. I should know, I was out riding mine today :whistle:

Can't wait for your pics
