K2-K6:
Can you physically see that any choke influence has been removed when you feel it's off?

I'm not sure I understand your question, I'll answer it two ways.

1st, with the choke applied after start up the bike starts dieing and becoming unresponsive until the choke is in the open position. The bike will not run with choke closed.

2nd, with the carbs off the bike, choke in open position the plates were horizontal and equal. (minimal interference with flow)

K2-K6:
Yep I asked that in a bit of a clunky way....you've said what i was getting at though, i.e. are you sure the choke is off when you think it is, so shouldn't be causing these symptoms.

I know what you mean by a weak spark but I've yet to experience that result (weak spark shows as rich mixture) there's always a first time i suppose but I've usually found that if the spark exists and is on time then in general it doesn't show such a severe fault as this. worth checking through to assure yourself of not missing something.

It's a bit more difficult when it's not in front of you, but I'll try to think what else to look at. Let us now what you find with the coils.

paul_D:
coils are new

But I think poor grounding and connections between the charging system, the reg/rec and ultimately the coils.

LesterPiglet:
Surely if you lay the plugs on the engine and turn the engine over and get a fat spark that's all you need.
Is the advancer operating?
