Remove stepper code and TPS code permanently

I didn't like the sound of stepper motor hunting, when I turned the key on.

when i was playing with mine if it was not in the correct position (or close to it) then it would keep adjusting it out till it reached fully extended.

I expect the cold start fast idle is likely tied the engine temperature sensor.

that will be my first checking thanks
and the air temp may have an affect on it also.
seems to be a daunting task when no one else in world has posted this is the fix.
 
Maybe I've just been lucky, but ive always set the idle stepper, TPS and all the associated bits as per the manual, and not had a problem, in all my rooting and bollixing at these engines
 
Personally I think it's a glitch in the software. On mine anyway, when it would start doing the 2 grand idle, if I hit the kill switch, flipped it back on and hit the starter button, without doing ANYTHING else, it would start back up and idle at the correct speed. To me, that rules out a mechanical problem.
 
FYI -
Claviger, Rob, is working hard to finish colege and doing his intern job.
He's shelved motors until next year, 2026.

Hi RS, I'm having the same problem with stepper motor. Tried everything I know & it's bugging me now!
Could you explain how you wired the resistors in thanks. & does this mean there is no need for the stepper motor & second tps anymore??
Many thanks

What I did. Removed the stepper motor. Using a volt meter set to ohms, Measure criss cross across the plug on the step motor. Write down that number. Measure criss cross across the other two terminals in the plug. Mine were 8.6 ohms if I remember correctly. Whatever reading you get, by some 1/2 watt resistors of the that value, (or as close as you can get). Then wire them into the plug that stayed with the bike. I made some terminals so I could keep the plug if it had a problem. If I was going to do it again, I would cut the plug off and connect the resistors direct. Use shrink tubing or tape thoroughly so they don't short to the frame or to each other. Tuck them up out of the way, clear the fault and you should be good to go.
 
Ok cheers, will give that a go I'm guessing you removed second butterfly's...
 
I get 8.2 ohms on the criss cross both ways on stepper & 12.55 on the plug both ways....
