Not realy a help question just want to learn, anyway wanted to replace the HT leads on my A2 which is running dyna s ignition posted a question on here asking do i use normal copper core lead but i think it was pigford said put silicone leads on it? and i didnt know what he meant, so i bought some today and the geezer in the shop said just cut the ends off and screw your plug caps into the ends, so i cut the ends off and instead of being copper wire its like well for want of a better description its like fibre, had me doubts but plugged other end into coils put the plug caps on and they worked so is this silicone leads and pardon my ignorance but how does it work without a copper core running through it

These are designed to pass the current with less resistance and cause less interference.

These have been around a long time, you do not find copper core leads very often these days.

Hope this helps.

OK cheers mate goes to show last time i had any ignition problems with a bike

I am also about to do this job - Does anyone know - Are the more modern leads compatible with the old metal spark plug caps?.... or is the recommendation to change caps as well?

There used to be talk of the old style metal plug caps shorting out in wet weather but I have never had any problems with mine.

cheers

Dont know kev i also replaced my old NGK plug caps with new NGK plug caps but yes i heard that about the metal plug caps shorting out in the rain.

Not 100% sure, but I'm not sure all coils have removable HT leads. I pretty sure that quite a few have 'sealed in for life' leads. I believe that most of the 'after market' performance coils have removable leads. Assuming mine has original coils the leads do look as if they're sealed in, there is no nut with gland or anything.

Be interested to learn more on this issue.

Ralph dynas coils that i got on my A2 have removeable leads, the ones on my MK2 which i assume are standard ones also have removeable leads.

All upto Z1000J had leads as an integral part of the coils. Js change to 2.2ohm coils.

If you want copper cored leads Vehicle Wiring Products sell it by the metre either plastic covered or silicone.

Ok, i know that you can change leeds on Kettle coils, the coils are a standard coil with some sort of epoxy to seal on the leads.

You grind away the epoxy which leaves you just to be able to pull off the leads. What you are left with is a round hole with a copper spike. The spike fits in the centre of the HT lead. I sealed mine back up with silicone with no probs
hope this helps ...
