KZ750 ignition timing question.

It should be as in the photo by loudhvx. Also, just a note: do not turn the crankshaft by using the smaller timing advancer bolt ---- instead, put a 17mm wrench on the big nut.

1981 KZ650-CSR.

Awesome!
ThanX as always.

Oh, should I have an earth tab or something going to that little red thing, with the brass bolt? It was naked and loos when I popped mine open?

That thing is the pressure switch for the oil pressure warning light. It usually has a blue wire (maybe with red stripe) attached to it, and that wire runs all the way up to the gauges to the oil light.

Ah, that makes sense, thanX loudhvx.
Looking better already.

If that advancing mechanism is yours, I would certainly push those 'E' clips off remove the springs, weights and cam, clean rust from those, polish the pins and resemble with a good lube, especially the inside of the cam and shaft..etc

Yep, all the sliding parts have been cleared, cleaned, then cleaned again with a brass brush and wet&dry paper with a little petrol, flushed off with some brake cleaner. All lubed up and reddy to go.
Nothing was moving at all when I started. Lol
Oh and the plug from the pickups themselves had bad corrosion on two pins. So that's had a good seeing to as well.
ThanX again to everyone.

The wiring diagrams show a blue/red wire for the oil pressure switch.

Here's a site w a pdf manual & wiring diagrams. mbsween. bike-night. KZ750L3 . Scroll down & click "The Bible" link.
Note: some of the wiring diagrams are mislabeled in the links: the 1981 Ltd is an H2, the 82 is an H3, & the 83 is an H4.

Good Fortune!

I got 2 of the screws out but the third is being a biatch. The previous owner must of been in here before and stripped out the screwhead so I can't get a grip to remove. Now i gotta get down to the hardware store and get some kind of bit to pull this out.

Thanks...

Are you using JIS screwdrivers ? if you're using Phillips screwdrivers you will ruin all the screws

I mark mine with type correction paint for my old eyes to see better. :whistle:
