--- Quote from: Alan T. Butler on August 14, 2013, 11:47:14 PM ---Has anybody seen a step-by-step demo of how to do the idle actuator calibration on a GS (or GS Adv)?  My bike is running fine, but I would like to try this feature.  Unfortunately I have read on some forums where folks have tried this and now their bikes idle very poorly, if at all.  The typical response from other posters is that the person probably didn't follow the procedure perfectly.  I would like to see this done before I try it on my bike. 

Thank you.

On what bike, Alan?

If it is the 1200GS, no adjustment is necessary.  It auto-learns every time you turn on the ignition.  That is why it is essential never to touch the throttle while starting or switching on the ignition.

Now to the question: When I run the TPS Adjustment procedure the bar rises always above the center to the right/"red" area (about 1"). BUT when I in this situation turn the throttle that couple of millimetres "off" like cancelling the cruise control against the spring / microswitch (cancelling the cruise) the bar lowers right back in the middle of the "Green". It stays there even when I let the throttle go.

Any idea of where/how to continue?

I recently had an R1150GS that did exactly that.  Found the cause after about 4hrs of searching.

Remove the RHS grip together with the plastic tube (accelerator grip) from the handle bar.  Make sure there is no rust on the handle bar where the grip rotates.  Also make sure the inside of the plastic tube that the grip is fitted to is clean.

Now apply a little grease to the handlebar end, and the inside of the tube.  Also grease the area were the cable attaches to the grip.

Lube the cable itself and make sure there are no kinks in the cable casing.  If the cable or casing look like they are corroded, replace.

Re-assemble and all should be well.  Will be like riding a new bike.

The symptoms you describe are all related.

The high idle is as a result of either 1. The throttle not returning 100% to the stop or 2. The engine having been started with the throttle not fully closed.  This will also account for the low idle at times, where the throttle does return past what the system now believes is "Closed"

It will also account for the bar moving to the right into the red zone when doing the TPS Adjustment.

- no fault codes in the system

From experience, if there are no fault codes recorded or displayed, the problem is mechanical.

hi don't know if you came rite yet or not but 0n the k1200lt at the throttle body adjustments there is two micro switches that works in co-ordnance with cruise control as well as idle. I have found that to mess me around.

just a penny worth

Any luck with the idle yet?
