"Floating" secondary.
Swapped out the NGK non resistor plugs for brand new correctly gaped NGK resistor plugs with appropriate non-resistor NGK caps.
Checked valve clearances and all are OK.
Thanks @Team Junk (Jack)Adam
Been away for awhile.
I would check your coil. Intermittent spark problems a lot of times are caused by breakdown of the varnish on the windings of the coil. A cheap Honda 750 coil repop would be a easy test.

Will do JanWell not read so carefully but a few TCI s have been tried
The carburetors looks clean as in a surgical clinic ..and has been serviced
Assuming the battery is fresh and charged
I am at poor power supply to the ignition box coils or the left cylinder as been suggested here
Most likely the box.
I don't know much about Gonzo but if it is a Waste spark system i would look into shifting left electrics to right and right to left see if the problems follows.
I would then check the power supply all the way to ignition box and coils
I would most likely draw a temporary separate wire . All the way from the battery to be sure the power is there and a separate ground so it is there NOT leaving the power on the coil or box it can fry i sometimes use a switch on that wire
Cheers @WingedwheelHang in there Adam. Hopefully swapping wires will tell you where to look next.
I am a novice here. I have two bikes now in the last 2 years. Both had dirty contacts/high voltage loss through older dirty ignition switches. We all need to remember our friend and mentor @grzld advice, "ignition first"...Will do Jan
The battery is brand new and on a good quality battery keeper.
In fact the whole system is brand new with the exception of the rotor system (which all looks new). charging system is working well.
I don’t have a kill switch, the iggy key is used to switch off.
Thats the only ‘old part’ in the system.
I will look at your other suggestions over the weekend..
Thanks as always.

Hello Jan,Any developments ?
I have those carburetors rarely --- 5 tines over 40 years giving any major problems
Have been cleaned here
Electrics however I have had problems with every year for 40 years
If i remember right it is misfiring on one side only --- to sum it up in my view it is an electric problem So which Electric problem then ?
The shifting of ignition leads left to right and vice versa could help If the problems follows
But I do know from a Boyer system That checked out on one cylinder when the mechanical regulator started to overcharge.
When hot
The left cylinder ..even though the system had the same overcharging It never stopped the right side
Replacing the regulator and rectifier solved it without new Alternator Rotor
I assume you have a Voltage measurement on the bike
One possibility could be to install another or the same on the supply to the Ignition Box .
I don't know your setup but one way forward could be to disconnect the charging circuit and run on the battery only.
It can be done for a while getting it warm and hot --- if it is a heat dependent problem in the charging circuit it wont disturb the ignition if it is Disconnected
Vibrations then ?? could be But in my view It is a partial short circuit when warm feel free to disregard if these have already been tested
If I understood that, are you shutting up the furniture store? I had no idea your business was in difficulties, well, why would any of us.. . . Right now I’m busy closing down my business, due to Putins economic fall out! . . .
Yes Raymond we have pulled the plug.If I understood that, are you shutting up the furniture store? I had no idea your business was in difficulties, well, why would any of us.
I have a very good shed in the garden for my tools, bicycles and other portable kit.So sorry to hear of your difficulties, Ads. Hope you can find a good way ahead.
Oh, and for the bikes, there might be the option of a shed?
Install a winch* in the shed?
* A winch Adam, not a wench.... though I suppose a wench could be taught to properly push a bike uphill.
Might even prove entertaining...
