Anybody adjust their Throttle Position Sensor?  I believe mine to be out of adjustment as the SD idles erratically and stalls frequently.  Other attempts to correct the problems have failed.  The Euro based SD forum is somewhat difficult to read due to none of them speaking plain English.  
One problem I'm having is not knowing much about the Centech multimeter to set if for measuring volts.  The other is which of the 3 wires do I measure?

Update: (if anyone really cares) I was unable to get the correct voltage.  Took it to the dealer.  As a test.  They will either enjoy learning the KTM street bikes or my bill will be high enough to buy a brand new KTM.  Turns out I need a new TPS (maybe I f'ed it up f'ing with it, f it) and were able to get one from KTM which is apparently rare.  This would usually require the purchase of new throttle bodies ($1k).  They installed a new fuel filter (whick I coulda done) and advised me that the O ring was gone, disintegrated.  And now I suppose the TPS is on a donkey's back coming across a mountain chain somewhere in Austria.  But the dealership is doing very well calling me periodically which makes me happy.

At least you have a KTM dealership, dwell on the positive.

Idle has been fixed finally.  Just had to adjust the screw that controls the butterflies off the throttle.  The front cylinder butterfly was opening slightly before the rear so I turned it up 3/4 of a turn and she idles without stalling at all now.  So happy to have this fixed finally and it was so easy.

Not all who wander are lost. I probably am, though

At least you have a KTM dealership who calls. The local one here... doesn't.
