There are four exceptions to this policy:
1. As permitted in Classifieds (consumer-to-consumer transactions).
2. An item may be offered for sale as a consumer-to-consumer transaction in any forum where there exists reasonable expectation of being welcomed by another member who has previously posted in the thread ("cold calls" and "door-to-door" solicitations are prohibited).
3. Each member is allowed a simple link (somesite.com) in their signature, which link shall include no description of any kind.

KEEP IT CLEAN
You may not post libelous or defamatory messages or materials, or include links to such materials in your postings. You may not post messages that are obscene, violent, abusive or designed to harass or intimidate another individual. Pornography, Warez, or any other illegal transactions may not be posted or included in members profiles. No blatant nudity.

BE CIVILIZED
Don't use racial, ethnic, or gender slurs, religiously derogatory comments or any other personal discriminations even in jest. Use of slurs needlessly offends people - whether or not they're a member of the group you've insulted. Respect others' religious beliefs and culture. Recognize that others have religious and personal beliefs which may differ from yours. Stay away from political debates. Keep the language and behaviour appropriate.

USE DESCRIPTIVE THREAD TITLES
When you post a new thread, please give users some idea of what it contains in the title. Thread titles like "Help" or "Check this out!" are cheap ways of getting users to look at a thread they might not care about, and would not have clicked on had the full title "Help, I need credit card numbers!" been used. Furthermore, it helps stop multiple threads on the same subject. When starting a new thread, describe the content of your thread clearly in the 'Subject' line of your post. Don't use vague subjects. Use descriptive and specific subject lines. This helps others decide whether your particular words of wisdom relate to a topic they care about. For example: "HELP!!" is not an appropriate subject and neither is "My bike doesn't run".

PLEASE DON'T SHOUT!
That cap lock key wasn't invented to help you get your message across. Messages written in all caps are annoying, hard to read, and loud.

HAS IT BEEN POSTED ALREADY?
Please look for an existing thread on a subject before you post one about it. Chances are good that your question has already been answered. There is a search feature on these forums, use it. Starting topics that have already been answered in great detail is a waste of everyone's time. Look to see if information you're about to post has just been posted by someone else. Then go ahead and post.

WE HAVE SECTIONS FOR A REASON
The Technical Forums have different sections for a reason. If you're not sure, use your best judgment. 

DON'T CROSS-POST
Cross-posting is when you post the same message multiple times in various threads or forums. We only need to see it once guys. 

STAY ON TOPIC
Keep threads on topic. If you've got something completely unrelated to say then start a new thread. Unresponsive solicitations for consumer-to-consumer sale are prohibited as being unrelated and off topic, but solicitations for consumer-to-consumer sale may be posted in Classifieds.

CONSIDER THE IMPACT OF YOUR WORDS BEFORE POSTING
Adhere to the same high standards (or higher) of behaviour online that you follow in real life. In real life, most people are fairly polite and law abiding. The same rules of behaviour are expected on any list.

MESSAGES SHOULD CONTRIBUTE TO THE TOPIC BEING DISCUSSED
or introduce a relevant idea. If you've read enough threads, you've already learned how annoying it is to go through "Me Too" posts. A "Me Too" is a post that says "I agree with what the other guy said" and otherwise does not add to the content. If you have a comment about someone else's post, tell them via U2U or email. Generally speaking, unless it concerns the entire group and is within the group's stated purpose, you should reply only to the author. Avoid replies or responses to the whole list of yes, no, or "I agree!". This is meaningless and you too would be annoyed to open such a message.

Dyna Coil Installation KZ1000 Ltd 5 years 5 months ago #289352

Hi, I am just installing green 3ohm Dyna coils to my KZ1000 and I am not sure which plug leads attach to each coil. Is it 2 & 4 that attach to the left coil and 1 & 3 that attach to the right coil (facing forward on the bike). Also does it matter which whether these leads connect to the front or rear towers on the coils.

Many Thanks

1/4 attach to one coil, 2/3 to the other and no, doesn't matter which tower you connect to.

As for left/right coil you can't really be sure on an old bike that might have been modified along the way - what matters is how the coils are connected at the timing plate.

Remove your ignition cover and look at the timing plate - the left set of points (or pickup if you have electronic ignition) trigger the 1/4 coil, the right set of points/pickup trigger the 2/3 coil - one will have a black wire, the other a green.

Connect the black and the green wire to the coils so the wire from the left set of points/pickup connects to the coil that has the 1/4 plug wires and the wire from the right set of points/pickup connects to the coil that has the 2/3 plug wires.

That explains why two longer NGK plug caps were attached to one old coil & two short ones to the other.

Than The 3 Ohm coils will not work. You require 2.2 Ohm Coils otherwise you will blow your ignition module. I almost made the same mistake on my Scratch built GPZ1100. Fortunately I caught it in time.

Kawasaki used 2.2 Ohm systems from the first electronic ignition systems threw about 1990 when they switched back to 3 ohm. You will eventually burn out your module or your coils. Your system will run very hot. If you check your Kawasaki manual it will tell you that the coils must test between 1.8 & 2.8 Ohms. If they test at the low side the spark will be weaker, If they test at the high side the spark will be stronger and the system will run hot. The only exception to this is the 1300 which did run a 3Ohm system.

Okay where also using Dyna-S ignition and by-passing or discarding the igniter.

The oem ignition, igniter and lower ohm coils work together. The Dyna-S ignition replaces the oem ignition and igniter, and works with the green Dyna 3ohm coils.

Good Luck! :)

Why is this? I've used three-ohm coils for years with the stock ignition.

Obviously, 3-ohm coils will use less current than 2.2-ohm coils since they have higher resistance. This means the ignition will run cooler, not hotter. BTW, Every stock Kaw electronic ignition coil I've measured was from about 2.4 to 2.7 ohms, but they are old.

Are you saying the primary side's induced voltage (in the 400v to 600v range) will be higher in the 3-ohm coil and possibly damage the output Darlington? But the protection Zener should bleed off the excess until the spark can initiate. Then the primary side is only around 50v... well within the Darlington's safety limit.

I'm not necessarily disputing what you're saying, but just wondering the reasoning.

Hi Thanks for all your input.
I am now completey confused as to whether the green 3ohm coils will be Ok or not.
I looked on Ebay and have even seen 1.5ohm used red coils advertised as being suitable for KZ dragbike etc. Would you need a ballast resistor in the supply voltage to the coils.

What would be the effect of using a balance resistor with the green 3ohm coils. I am reading that it increase the batery voltage for starting the engine and then it decrease the voltage when the engine is running.

Advice on using the green ones please, Yes or no.

I do stand corrected. I have read threw everything that has been written on this thread so far, just to review. And I spoke too soon. By using a coil of to HIGH of resistance the output voltage from the secondary winding will be lowered. It may go down as low as 20,000V from the advertised 30,000V. This is a significantly weaker spark from the manufacturers intentions, and may result in spark "blowout". If the 1.5 Ohm coil is used, a Ballast resistor will have to be installed to raise the primary winding resistance to prevent system burn out. I do apologize for causing some confusion. Just tired I guess. :blush: :blink:

balance resistor with the green 3ohm coils or other sized resistive coils

Oh KZ god why..... :blink:
After all this is your spark power we're speak of, why throw other possibilities of failure or non ideal operations into the equation....

Z1 has both the coils (GREEN 3 ohm) and the Dyna-S ignition plates... ~ $120 each. These are basically designed as a match set for your bike.

Install, align, check your ignition timing, done with it!
For the most part, never have to worry about it again. ;)

The green 3.0 ohm coils should be ok for your bike. They will use less current and I think Otakar is saying they'll be safe, but possibly have weaker output than the stock coils. I use Accel 3.0 ohm coils, which if I recall, are electrically very similar to the Dyna 3.0 ohm coils.

Your stock ignition is functionally the same as the stock ignition on my bikes, and the 3.0 ohm coils work great for me. Also, the 3.0 ohm coils will give you the option to go to a Dyna S if you want to in the future. However, the Dyna S produces more spark energy at very high RPMs, but wastes a lot of power at the lower RPMs. This is because of it's fixed, super-long dwell. Your Kaw ignition varies the dwell slightly so is far more efficient, however above 7000 RPM or so, the dwell is still only about 1/3 that of the Dyna S. Luckily, the 3.0 ohm coils seem to have no problem with that, at least in my experience.

Also, on the subject of reliability, if the 3.0 ohm coils somehow damage your stock Kaw igniter, you can fab one for very cheap. Here is a link on how to do that:

Geocities will shut down this year, so I don't know how long the link will be good.

I will go with the greens for now.
Got a spare set of greens that I will sell on Ebay uk. As I have seen a pair of grey 2.2's for sale. Could maybe break even on the deal- I have a couple of spare igniters knocking around too, amazing what you collect over the years "just in case".

Thanx a lot for that link. That is fantastic. since I have a KZ1300 also, and ignition modules for those are about $200+++ USED I can very easily build one with these. This is really great. I have already saved the Schematic to my computer. This would mean that I can build a new module for less than $75 with everything, for the 1300. Thanx again.

I'm glad if you can use it Otakar. Luckily, you have the 79 and 80. The 81, as I found out through emails with a 1300 owner, unfortunately uses electronic advance. The module for that bike is really hard to get, at least at a reasonable price.

I haven't tried it, but the HEI mod should work on the 79 and 80 1300-6.

I'm sure you can figure it out, but if you need a diagram for a 6 application, let me know.
