Electronic Ignition Recommendation

[289 cobra]

I have a 1975 900 that is all factory stock with about 16K on the odometer. I would like to get away from the point system and upgrade to an electronic unit. Any recommendations? Do I need to replace coils also? Best source?
Thanks,Steve

get a dyna s ignition.it will run with the stock coils but you can use dyna coils if you want to.

Yup, the Dyna S seems to be the way to go on our Zeds.

Thanks for the info. I will get some pics posted as soon as I get the covers back on it.
This is actually my 3rd one. I had a blue 75 that I purchased new, which was stolen in 76. I then purchased a like new red 75 which went away when I got married. (should have skipped the marraiage and kept the Kaw) Great bikes!

Many guys at KZrider.com - Home have done a very simple wiring modification using a 40 amp automobile relay to bypass the aged wiring on these older Kawasaki's. To see if your bike could benefit from this, remove the gas tank, and with a fully charged battery, turn on the ignition but don't start the engine.

With a meter, check the primary input terminals on the ignition coils(smaller wires) it should read battery voltage or real close. If it's down around 8 volts or less, your bike has a voltage drop that will affect the spark energy output.

After doing this modification, your bike should be much easier to start with increased combustion efficiencies. The website www.wgcarb.com has instructions on how to do it along with parts needed. His website also has a similar forum for questions.

MFolks, thanks for the info. I will check it out. Just ordered a Dyna S ignition from Z1 Enterprises. Can't wait to get it on. What prompted this was that the mounting plate for the points came loose while driving, and it started missing very bad. I took the points cover off and 2 of the 3 mounting screws were laying in the cover! Of the 2 other 900's I have owned, I never had problem one with the points.

Use some BLUE Loctite # 242 on the screws and they will not come loose(except with tools) Do not use RED Loctite # 222 as it needs about 300 F to looosen it's grip.

I seem to recall seeing a note on Z1 Enterprises web site that showed two different ignition advances. IIRC the Dyna ignition only works with the newer style advance.

I believe what I read was that there were 2 different advance mechanisms, one used on the 73's and up to 75. Mine has the later mechanism, so I hope it won't be a problem.
