No spark

thanks, im just trying to find the pulsing coil for less than $121 and i know theres gotta be somewhere out there that has them for cheaper

Just to clarify; in an earlier post you stated you had points. I assume that is not actually the case as you are trying to locate an inexpensive source for a pulsing coil. So is the part you're looking for the one circled in the diagram below (part number 59026-1058)?

The original ignition for that bike (84 KZ700 A1) is the electronic-advance version. You'll need the aluminum-frame pickups (pulsers) with the square-tooth reluctor rotor. It will not have a mechanical advancer. It will require the larger box-shaped igniter.
That system is harder to come by.

You can, however, downgrade to either of the older ignitions.

The older kz 750 ignition will have the same coils (2.2 to 2.6 ohms), but will use a cheaper igniter box (which you can easily make) and will use the more-plentiful older style, steel pickup plate. You will also have to use a mechanical advancer from a 650 or 750-four.

You can use the pickups from 550's, 650's, and 750-four's.

Advancers from those bikes may fit, but the advancer curve might be better if the advancer is from a 750-four.

And then you can probably use any points setup from a 650, but those require higher-ohm coils (about 4 ohms).

If he needs an igniter there are a few used ones on eBay, but they ain't cheap -

Lack of spark at plugs could be caused by lots of things besides a defective pulsing coil.

How do i test the igniter box? Im really at a loss on this because it feels like iv tested everything....

Here's a 1983 KZ750 manual, but am uncertain about any changes in 1984.

Good Fortune!

First, lets all get on the same page.

So you are saying you have the original electronic ignition from that bike, and not the points you originally said you had, or did you find the parts and re-install them and remove the points?

Second, how exactly are you checking for spark? If you have the sparkplugs all disconnected, then you should ground one sparkplug wire on the coil you are testing in order to check the other plug wire for spark.

Also, just so you know, the coil on the right should go to spark plugs 1 and 4, they are the outer plugs. The left coil should go to spark plugs 2 and 3, they are the inner plugs.

Who's on first? :lol:

Whats on second? lol

Ok so i did some more probing and dropped the bike off at a friends house and had some other friends take a look and we have come to the conclusion that it is the igniter box...i know i have been very off and on with all of my conclusions but im pretty sure this time lol. and it doesn't hurt that i found an igniter coil for $82

ok so i fixed the spark issue!!!!! after many hours of testing and probing and taking it to a few friends. we came to the conclusion that it was the igniter box and i found a used one on ebay for $80 bucks!!!! and i put it on and i now have spark. Now im getting spark and im getting fuel but it wont start?!?!


So any ideas as to why it wont start when i have spark and im gettin fuel?

How's the compression look? An engine when new/rebuilt might have 180 PSI, add some years, and it might be 160 or so. Engines will run at 100 PSI but produce little useable power.
