Just been taking the 600 (2000) loom out of my SRAD

Im putting in a 750 '96 loom to fit the 750 '96 lump so the original is coming out...

I was planning on using the original 2000 coils however I cant find the plugs for them on the 96 loom .... what I DID find was something a little different sooooo wanted ask a couple questions,

1. Are these plugs (pictured in 1a) the coil connectors ?

&

2. Do I need to source '96 coils to fit or can these be used dispite the diff plug casing ?

In the first picture....yes those are the leads for the 96 coil packs.

Second....it can be done, in fact I was just reading an article online yesterday where a ZX7 was being converted to stick coils from paired coil packs to make room for a different ram air box......I could look through the history on that computer later and find out more.

TT750 seems to have a much better grasp on electrics than I do....maybe he will chime in here.

Ahh cheers for that matey, its trial error with this bike build as Im a total novice when it comes to mechanics but I'm learning all the time when you got a bike in bits lol

hmmm the 96 750 has 2 coil packs not the 4 coil sticks... you will need the 2 coils and the high tension leads.

TT750....what he wants to know is if he can use the stick coils in his harness with some adaptation to the connections, and NOT use dual coil packs and high tension leads.

I know it has been done, but don't know how to wire it and if the CDI's were different.

ah i would say not easily... off the top my head you could wire it to fire 2 coil sticks at once to the wires for 1 coil pack. coil packs use a waste spark setup. one spark plug is positive to the coil pack and the other spark plug is the ground. so it fires the coil making spark in 2 cylinders. 1 them being on compression and the other on exhaust stroke. i always thought the ignition controled the ground side of the circuit. sowith out any research and off the top my head power 2 coil sticks with the power for one the coil packs then control the ground side with the single ground. i really not know if it would work to fire the sticks or if firing them twice as much as they normaly do would be good for them at high rpm. it takes some time to build up a magnetic field in the coil. also you get into the ohms of the coils. i always thought when you changed to a dyna coilpack you had to get the proper ohm coil for you cdi. you could damage your cdi maybe...honestly i have not looked much into it as if i was to upgrade a coil pack i would go to a dyna coil and maybe even an dyna 2000 ignition module on a older bike. i can't see the gain from going from the coil packs to the sticks.. i have to wonder if any the bandit or older oiler guys have converted to coil sticks..

i really not sure if you would be opening a can of worms with this electrically. electrons do funny things sometimes. if you have the coil packs i would say use them.

I'll keep it simple and just buy the old ones I think... :cheers

Its just cos I had the newer coils off my original loom I wanted to see if I could use them but if it means doing a lot of messing around I'll leave it

Cool . . You could get dyna coils for it

or you could use ZX7 coils and Nology wires....I might even have some unused adapters to mount the coils around here.

Are there any performance increases using the bits you mention or is it just a easier way of going about it ?

Have never put that particular change to test on a dyno, but have used the Nology Hotwires on ZX6R, ZX7/R, ZX9, and GSXR's......and they have all idled and carburated better, and I never have any fouled plugs.

More spark is always a good thing

Thanks fellas !! You've sold me then!

Dont mean to sound lazy.... BUT have you got any links to any that would fit my '96 ? Its not that I cant be arsed to look as I've already googled the bits you mention, just I have no idea what Im buying lol :scratch

hold on, it is NOT that simple. I don't care what Nology or its employees say (I have about 10 phone calls to back this up)...you cannot properly attach the Nology wires to stock OEM suzuki SRAD coils. Options:
1) Buy Nology coils.....I have never done this and cannot offer any advice
2) Purchase used ZX7 type coils off of EBAY for next to nothing.....the Nology wires go right on to them as they use a compression type cap that threads onto a screw type post. The only thing is that you need to machine a little bracket in order to get your bolt spacing back to what the SRAD coil spacing is. If anyone wants them, I have a set that would work, but are not as nice as my current versions)

Here is my other thread on this with PICTURES:

Just ordered these off an '89 Kwak ZX750 H1

Assume they should do the job ???

I would got newer ones as there is some one eBay

Yup, you just need to fab up a little block/bracket to adjust for the difference in bolt spacing and you are good. Here is a pic of my setup...

When you unscrew the compression cap that hold the wires to the coils, make sure that you reuse the little compression pieces underneath it on whatever wires you choose to adapt.

I would got newer ones as there is some one eBay

I saw one off an SRAD but all the others were either incomplete or the ones I already got :(

These were the only ZX750's I could find, but they were off the UK ebay, I didnt look on .com as postage is usually a bit of a killer

Why not run the 750 motor on the 600 loom and ecu so you can retain the stick coils, which give a far better spark. Yes the 600 has a higher rev limiter, but thats no bad thing as long as you're pinging off the limiter all the time. The 600 ECU also advances the ignition a little more, so your 750 will be slightly fitter into the bargain too. I've done quite a few 750 motors into 600 bikes, and always have retained the 600 loom etc. Works a treat!

And you defo can't run stick coils off a loom running coil packs. The discharge/recharge times are completely different, and just won't work.

i thought there was differences in the 750 electrics and the 600.. the crank pick up maybe.

Nope, all just plugs in. Only difference may be the gear position switch, early bikes had 2 wires, later bikes have 3. Switch swaps straight over though, so no drama.

I had an extra lead left over which caused the ecu to tell the engine not to start, I was told a way of bypassing it but it was a lot to take in over the phone :scratch

I havnt really gone about things the best way with this engine upgrade mainly due to me rushing it back in June to get it done before the TT but ran out of time and had probs along the way.

Originally I got it running on 3 cylinders with the 600 carbs on + 600 loom and 600 ecu, unfortunately I didnt get that sorted in time, now its winter I've got round to trying to get it going, Im hoping it aint a dropped valve but a cold compression test just getting it to turn over on the starter gave consistant 90psi readings, gonna have another go at it once I got all the right bits
