Best Performing Ignition Leads for Standard Engine ?

7mm copper core ignition wires(some places call them "High Tension" leads).

Ignition Coils And Sparkplug Wire Choices:

What came with the bike were ignition coils that even when new were marginal, add years of cooking under the tank in stop and go traffic, and the coils will fail when hot.

Replacement coils can be bought at www.z1enterprises.com. I believe "Emgo" is the brand. They also carry the popular Dyna 2.2 and 3 ohm coils along with replacement sparkplug wires.

Now, you have a choice on sparkplug wires:
1. Copper plug wires with no surpression caps(the best choice, will produce greater spark, but will produce audio noise on Radio's & T.V.'s)

2. Copper plug wires with surpression caps(a built in 5000 ohm resistor, that can some times fail, like what came with the bike).

3. Copper plug wires with no surpression caps, but using resistor plugs(the "R" in the plug number, like B8RES).

4. Surpression plug wires with no surpression caps.

NEVER use resistor plugs and surpression caps or surpression plug wires, as now there will be two (2) sources of resistance in the secondary loop of the ignition coils, greatly reducing the spark energy.

Another choice is the Accel 3 ohm coils, with a similar primary(small wire) electrical connection using ring terminals as the Dyna ignition coils. Whatever brand of coil you go with, make sure the primary wires will clear the mounting hardware, as the spacers will come really close, possibly causing an electrical short, blowing fuses. Some riders have replaced the metal spacers with Nylon or Plastic non conductive ones, reducing the chance of an electrical problem.

I like the 8mm Taylor wires. These are a non-resistor wire.

Have 7 mm High tension single copper core - Narva brand so thats as good as its gonna get
Live in the country so bike has rairly sat in traffic or at lights thats a bonus - always just a minute from the highway. Have a couple of spare coils.
Been using D8EA's for a little while - (D8ES replacement) better idle than DR8ESL (original) .
Thanks for Taylor suggestion - its like anything , there are too many brands to choose from ,
Coils next on my list.

Would it make any difference to have all ignition leads exactly the same length ?

Not really...NO

just try to keep them as short as you can.....really don't need tons of slack in these wires, but give them a bit of room don't so you don't create a pinch point due to pulling them too tight to hook up.

Thanks 4TheKZ1000 about the length of leads - always wondered about that one.
I have them just as you have described .
Thanks MFolks for all the info.
Not sure about all the different coils though (ohm ratings etc).My standard ones have always been perfect for me and it is very smooth already but always looking for improvement.
What specs do i need to look at to update coils ?
Another dumb question. kzrider.com/media/kunena/emoticons/smile.png

You just need to make sure the resistance of the coil is correct for your ignition. If the resistance is slightly higher than stock, probably not a big problem but going lower resistance than recommended can cause the coil and the ignition drivers to cook and maybe blow out.

Thanks bountyhunter

On all my bikes I prefer 7mm, they fit in the coils better, 8mm needs trimming around the circumference which is virtually impossible to do neatly.

I wish suzuki also used removable HT leads .

Only just got off my ass the other day to check exactly what leads were on my bike - 7mm HT.
Damn slack i know !

While Suzuki "HT Leads" are not as easily removed as Kaws, once dug out they do not require the caps and o-ring that Kaw wires/coils need. Six of one, half a dozen of the other.
