Looking for info, and possibly known sources y'all use, for engine info and parts. I just picked this half thrown together project up for a mere $250 US. May have overpaid, I'll be honest. Not much works and numerous shade tree mechanics have made rediculous attempts at repairs. Long story short I have my work cut out. I am actually considering getting a different KZ750 and using this one for parts..

Someone tried to make this into cafe style racer..no rear shocks, no paddi g on seat, loose screws everywhere..antifreeze , I think, in the rusty fuel tank. Has good compression but no spark..Open to your guys opinions on this one..

This is my first post here. 🙂

I believe the KZ750 Twin engine was pretty much unchanged through the entire model run from 1976-83.

The 750G Ltd II is probably most similar to the 76-79 750B models, and I'm pretty sure they have the same points ignition. The 82-83 750M/K models had electronic ignition which you can install on your bike. You can use the pulsing coil (ignition plate w pickup) from a KZ440, but you'd need the advancer from the 750M/K. The charging systems can vary & I'm not sure how interchangeable they are, but you can probably stick with what you have.

The motorcycle needs a good, fully charged battery to power the ignition system & run right.
You should check it with a digital multimeter & do a load test.

For parts, first thing I do is check the diagrams at Partzilla, then search the full part number over on eebbaayy to see if NOS is available, either for purchase at reasonable cost or for a good photo to see what a new part looks like. Then I search the part by name & alternate moniker.

Z1Enterprises . com has maintenance & other stuff for the motorcycle. If you need to do wiring, they have colored wire which is kind of handy, so that you can try to keep things close to stock & similar to the wiring diagram.

A motorcycle salvage yard might have some stuff. There was a good one near me, but it closed down a couple of years ago.
