GS650 replacement ignition coils

Hello. I have a 1982 GS650GL with bad spark plug wires. They're visibly cracked and arcing in a few places. They appear to be original, which I believe means they are part of the ignition coil assemblies. Has anyone found suitable aftermarket replacement parts for these? I've searched high and low and can't find much. I can't be the first person to come across this. I tried searching this site but can't find where this question has been answered before. I'm new to bikes (this is my first one) and to this forum, so please forgive me if I've overlooked an easy solution on the site.

Thanks,
Brian
 
You could try removing the old plug leads by getting as much of the epoxy off then grabbing the lead as close to the coil with players and moving backwards and forwards to loosen the wire alternately being very careful dig out the old wire there is a small post at the bottom of the coil that the centre core of the cable fits on,be careful not to break it you can the glue/epoxy new cables in.
 
They can be replaced. They are epoxied into the coil towers and a real PITA to remove, but it is do-able.

Thanks for the reply. Sounds like it can be done, but obviously wasn't intended originally. I'm really shocked there is no direct replacement for these. Maybe the 650 model wasn't super popular?

If you decide to go the route of replacing the coils, the Dyna Greens (3 ohm, dual output) are (almost) a direct swap. You may have to rig up some sort of offset spacer/mount to get them to fit, but they will work.

Z1 often has the best pricing on the product, and they have all of the wiring you need to rig them up as well.

Thanks for the info! On a longshot, I just called a local Suzuki dealer and they can get the original coil assemblies for almost the same price. It's more than I hoped to spend, but it sounds like my only other option is trying to remove the wires from the existing coils...which doesn't sound too fun.

No but it's a hell of a lot cheaper 😀
 
If it is just the wires cracking and the coils are still good, you could go to any auto parts store and get enough heat shrink tubing to shrink two layers on the wires and that would end any arcing problems. Auto parts stores usually carry heat shrink on rolls, so you can buy whatever length you need and they carry it in large sizes, big enough to fit over spark plug wires.
 
Excellent advice Earl. Sounds like a pretty easy fix for the OP's problem.

That's a great idea. Thank you!
