    This is my '83 KZ750 F1 LTD SHAFT. I bought it a couple of months ago and haven't done much to it yet. As far as I can tell, it's got a large 650 tank, custom fiberglass seat, rear fender cowl from a different model, dyna ignition.

    I've brought the valve lash back into spec, ignition wiring & plugs, replaced/tuned the carbs & rubbers, and added the cheap emgo 1/4 fairing, European bars, that's about it.

    I have an American Classix hydraulic slave for the clutch on order which I will pair with my KTM master. Should be pretty sweet because the cable clutch is kind of a sore spot when riding.

    Getting about 45mpg fuel economy right now with highway riding. I think it'll do about 50mpg when tuned proper. Though the speedo is kinda busted as it only goes to 85 and sits there for some reason :lol3

    My kid picked this up last spring. It's a little rough but we fixed a few things and he's ridden it all summer. Maybe this winter we'll get more of it straight.

    on this very model of bike, first gen Uni-track, be sure to inspect where the rear shock assembly bolts to the underside of the steel swingarm (the most under-engineered sheet metal tab mounting point, ever?)

    Thanks for the tip! We'll be pulling the rear apart this winter anyway since the shock is going to need some attention. The spring is really tired and the rear tire is gone.

    It was a memory riding one of these again. I raced one in '83-'84 and I'd forgotten just how nice they were. When he spotted the bike I told him he'd better snatch it up before I did. :D

    my first bike was a 1981 CSR1000. I absolutely loved that bike and it is the only one I regret selling. I had restored the bike but I had changed the seat, put flat bars on, and fitted the Vance and Hines drag exhaust (the one that rides high down the side) I have great respect for kzs and csrs

    That reminds me.. what is everyone running for coils on their KZ? I've got the Dyna ignition and I was all set to buy some proper coils when I checked my stock ones, which are 2.4 ohm. Somehow I thought the stock ones were > 3 ohm.

    Anyways, chasing a rather wimpy idle strength and am pretty sure it is spark quality related. Running copper wires with resistor plugs gapped to 0.028". Some have said the stock coils with a Dyna ignition can't really do well beyond 0.020" gap, and recommend the Dyna grey coils. I will probably reduce the gap and experiment a little. Other than not having enough tractor pull at idle it runs pretty strong.

    Has anyone sorted a way to put a non-vacuum petcock on a GPz? I'm about done with fighting the leaky ass stock unit, even post-rebuild.:banghead:

    Well here's mine, a '75 KZ400D. I bought it in 2003 for $300, then sold it in 2006, probably should have kept it but some parts were getting a little hard to find. With this being my daily commuter, I was putting about 300 miles a week on it, going through 2-3 tanks of fuel every week. It was pretty reliable for the most part, I kinda enjoyed having the kickstart. I installed a pair of dyna or accell coils to replace the dead or dying original coils and for a little hotter spark. I still have an original Kawasaki air filter for it, in case anyone is interested.

    When I was a youngster my very first Kawasaki was a z650 c3 bought brand spanking new in 78\79 this is a picture thats been pinned in my garage for the last umpteen years. A glorious day on holy island 30+ years ago................

    And here's my new one a 1977 B1 - an unexpected gift from earlier this year, imported from Arizona with 19k showing on speedo :-

    Dyna grey coils will work well with the Dyna ign (Dyna S or 2000?). Most Dyna boxes also don't like solid leads, the EMF gets them all crosseyed, so you might have to switch to R leads when you run the new coils. Grey coils and R leads mated with a close .028 gap should blow the head off the thing. It's all good.

    Actually neither. I took a look at the bike and my service manual and it turns out that I have the factory electronic ignition. I'll have to go read some threads about that.. I recall reading that it was a good setup.

    The std Kawasaki pointless ignition is pretty good....... :wink:

    However, best to check it is getting the full +12v to the coils...... all the stuff is getting on a bit old by now too !!!

    I just went back through the whole thread,, some great shots of some awesome projects. Got me to thinking that its time for a new project. I saw an old bike the other day sitting out in the woods by an old house, think it was a Suzuki,I never owned a Suzuki before so may be the time has come,,,
