Thanks for all the replies and ideas, guys The shop guys got a bit desperate and wanted the bike out of the place and gone...the former AUS importer's Nat. Service/ Warranty Manager also wanted to get rid of the issue as they are handing over the whole TR-headache to KTM-Australia in a couple of weeks....so they followed a couple of my hunches related to the issue of running fine as long as on choke/ cold settings...but falling over when switching across to warm/ normal settings. The GREAT news: the bike is running fine!! The bad news: I still don't know EXACTLY what the issue was. They cleaned the stepper motor, which didn't have much crud on it....and they replaced the CO2 sensor (lambda sensor) at the same time. The bike hasn't missed a beat since!!! Which one of the 2 did the trick?? No idea, but I'm fairly certain of the CO2 sensor. The sensor is also the easier of the 2 to get to and swap over quickly (if another suitable sensor can be sourced). No doubt it would have shown up right away IF the bike could've been hooked up to an OSS session....which will still be pie-in-the-sky-stuff for some time to come until some dealers adopt the full KTM diagnostics. The current sensor used is from a Husky 449/511, cut and spliced into the wiring. Somehow the idle is more solid and stable than it ever was. Haven't ridden the bike beyond taking it around the block yet. Geeza also posted me an OEM sensor which I'll hang onto for a week or 2, just to make sure. A HUGE thanks, mate...and great to see the few and far-flung Aussie owners sticking together, helping eachother to keep their bikes going. I'm sure that'll become the primary resource for everyone involved pretty soon....and I'd love to invite the Kiwis/ Malaysians/ West-Coast-Yanks and anyone else in the Asia/ Pacific "neighbourhood" to join in. In order to keep those bikes running we'll need each other, no question! Thanks to all for looking into this thread, at this stage it looks like a Happy Ending! Hope it'll be all ride-reports and pics from hereon in....
Great news! It could be worthwhile for anyone having similar issues to either replace the sensor or try the O2 sensor eliminator plug as supplied with a Powercommander. They are easy to make with a few resistors.
From what I know (could be wrong) this ONLY works together with a PC, not as a standalone. ECU doesn't work well with constant input values.
You could be right. Some do and some don't. I know certain kawasakis have the same controle system. When the ECU detect a constant value from the O2 sensor it trows up a fault code. On the other hand, Italian Huskies, KTM and others no problem.
I prefer Lanolin, can be sprayed on, it's "wicking" properties it ensures that all joints are improved
