, blue paint in tact and pot set...
The blue paint flakes off on a lot of bikes so i wouldn't use that as a sign they've been tampered with.

FWIW there are no volts settings needed for throttle potentiometer calibration, the ecu learns 0-100% and a GS911 can be used to check TPS output.
A simple TPS reset procedure takes 2 minutes, during which the ecu relearns the settings.
There's the cause of your rough running!
I know this is now an old thread, but why is it important to disconnect or park the stepper motors before carrying out throttle balance? Why can’t you just fit the gauges and do it with them connected?? Sorry relatively new to GS mechanics.
Brilliant I’ll give it a try, must admit I have set them up with the stepper motors connected as I didn’t know any better.The ecu is constantly moving the idle air bypass stepper motors to regulate a steady idle. It is bypassing air around the throttle butterfly and fighting against any adjustment you make.
By parking the idle steppers to lock them out, you can then accurately balance throttle butterflies manually.

you ride the bike at low speed mostly with the throttle open and manoeuvrer in traffic opening and closing the throttle seldom hitting idle
thus you want the balance correct at the point where it matters - as the butterflies are just opening via the cables - idle balance is pretty much a waste of space - you also need enough air flow that you can make a sensible judgement - so always do on a warm engine around 3 to 4k (always held open via the throttle grip)

So regarding getting a gs911 tool what do i need? One of those triangular orange ones off of Amazon for £108 or the more oblong green and black one for around £300?
