Running rich?

Thanks Carver
I did the tests on the engine temp and air temp inputs on the ecu again and they were in spec.
Then I started it and it was all good with no smoke.
I will go back and disconnect them again to see if I can make it run rich again as I'm thinking its the engine temp input that might be the culprit.
Its hard to bask in the glory of fixing something when you don't know how you did it. 
Previously I  tested the injectors by extending the fuel line and running them off the bike and just observed the spray pattern.
The issue(s) has disappeared ( for now) so I will road test it.

Nothing like putting the bike on the 'healing' bench for an overnight recovery!

Fuel injectors were leaking and drowning the plugs on startup.
Extra smoke was from un burnt fuel in the pipes.
Also causes earsplitting backfires, went from 100mph to wont start, overnight!
Finally found new injectors, but starter clutch broke a spring.
Waiting for parts   
 

Hey. That looks like fun! Good luck.

Its back running on 6 but won't rev out.
Bought a noid light tester and the signal to injectors is breaking down when throttle twisted.
TPI is testing ok as engine and air temp etc.
Has got all new ignition system so reasonably confident of spark and engine speed to ecu. Fuel supply is good.
Have got good battery voltage to injectors and ecu. Grounds all testing ok.
Have disconnected the injectors and reading millivolts from the w/r (4) injector wire to ecu which builds to 200mv and then instantly to 0.30v and then back to zero volts ( which it should be ) before starting the cycle again.
So am getting a very small regular voltage spike coming the wrong way to the injectors from the ecu.
Not sure if this is normal or weird.
The ecu has travelled to vectriq in europe for testing and came back ok.
Now I suspect the ecu again.

 

Am intreresting read. Looking forward to hearing about your resolve.
