Below is the relay wiring diagram to control cold-start as discussed. Normally the 350 ohm will be in play but when the switch is activated it will move to the 1000 ohm resistor. I have included two versions, with/without optional warning light. Don't forget this is a "fix" and the underlying problem will still exist, also be careful where you locate the resistors as they may get hot (possibly not as the current flow is very small but better safe than sorry)

So I got a hold of a resistor from a coworker that works on old radios! Perfect 1/4W 1000 ohm.  Had a 2 position toggle switch, wire and stake ons in the tool box.  Put this together fairly easily for a quick test.  Started the bike under normal circuit, coughed and black smoked.   Turned off the key and flipped the switch, restarted the bike and it purred nicely, no sputtering etc… let it run for a bit and no issue.    

Curious, why do you suggest the use of a relay verses a 2 position switch?    Either way I need to find a home for the device under the seat so it’s hidden out of sight and the resistor has some space around it for proper heat dissipation.    I really appreciate the relay diagram,  very clear to understand. Now I need to source a relay from Amazon!

 

Either a relay or a "two position switch" will do the job (current is minimal so the switch could handle the current Ok) but by using a relay (depending on where you locate it) there are a couple of benefits

1. You only need to run a single wire to the switch as you can "chassis earth" the other side close to the switch
2. You can reduce the additional length you are adding to the wire from the ECU through the resistor to ground so reduce potential volt drops
