I think you'll have a hotter spark.....

Can you get lead material with a higher resistance/foot?

Added 30 millimetres to the lead, its roughly 4 - 4.2 between them all, that is close enough not to cause any trouble.

Also the values dont shoot up with heat like the OEM did. By the way, the old stock ones were between 7 - 11K, so no wonder its skippin a few beats...

How many guys with stalling issues have changed the leads/coils? Now im even more confident than ever that these will cause serious issues with heat, even when new cos the material is low quality, not to mention 15 years of heat cycles and use!

My 996 Duke had values of 1,5 - 1,8K with magnecor wires, it totally transformed the bike when i installed them. Sadly i didn`t measure the old OEM ones.

Will keep you posted

Idle jumped up 250rpm to 1650rpm, it is a different bike on, and near idle, runs as smooth as butter!!

Why was i even doubting that replacing 15 year old leads and coils wasn't a good idea.

Stalling is gone....

@ViggenF4: Glad to hear the new coils sorted your stalling issue. Now you should lower your idle speed back to spec. I am sure that is on your agenda.

If I could ask you to put your bike model and year into your signature line through TOOLS>USER CP>SETTINGS AND OPTIONS> EDIT YOUR SIGNATURE

Because of the coils you were seeking, I assume the bike is a 750 F4. Having this info in you signature helps those who would want to help you.

Oh yeah, the coils are from Fiat Punto/Panda/Stilo 99 - 05. You can go to your local parts store and ask a reference coils for BAE 800B, used also on many Alfas, Lancias, Maseratis.... you name it.

Here is one place if too lazy to go on the counter https://www.bestpartstore.co.uk/7807...-ignition-coil

I used Accel 7mm leads and oem plug caps, but next time im gona use Alfa 164 caps. For the caps there are lots of choices, since surprisingly many manufacturers make caps with the same dimensions and values.

Now go change yours, but do your own research on the caps, im not promising what you can or cant use.

They are exactly like the OEM coils. Identical in every way.

BY "oem plug caps" do you mean that the end boots are reusable? You were able to replace just the wire and terminal ends while reusing the boots?
