1980 GS850 missfire

The caps are actually quite new. The leads are unfortunately fixed to the coils so I can't swap out the leads without swapping the coil.
I feel the issue may lie elsewhere in the ignition system tho. Are there any new ignitors that suit?

Pulled the plugs and they were jet black after an hours of riding. Swapped in new plugs, cut an inch off all the leads and reinstalled the caps. Ran a lot better but I'd be willing to bet the issue will return when I take it for a longer run tomorrow

Its nasty but a salt water mist in total darkness will reveal high tension leaks as an arcing light show. Beats using a hand and getting shocked.
if you try it. Rinse madly.

if it wires there's threads showing surgical replacement of the molded-in wires.

Hey guys I took it for a longer run. Was stuttering like mad so turned around and went home. Unplugged the connection from the ignitor to the coils, cleaned the and reconnected and it ran really well. Almost perfect. I only had the stuttering at the top end, WOT. The bike felt like it was topping out at about 135kmph up a mild hill and started stuttering.
Back off throttle slightly and it's all smooth.
Smooth all the way through. Standing starts, high revs and WOT had no stutter.
