I rode to work today in a periodic and ultimately relatively dense fog. Upon pulling into our driveway and slowing for a speed bump with the clutch in, the revs dropped very low (on the verge of stalling). The bike stumbled and I pulled into a parking spot. The idle dropped very low again threatening a stall. I revved it up a bit and the revs hung at perhaps 1500rpms before dropping to the low rev situation again. I shut it off, and it started, but back at low revs.
I assumed that perhaps the fog had somehow screwed up a possibly leaky spark plug coil or a TPS/APS/YCC-T sensor and that it would dry out by the end of the day. So, I started up after work and it ran at about 1800 rpms (cold?) and settled down to about 1300 or so. Oddly, it wouldn't allow me to switch throttle modes. Pulling through the parking lot, I realized that when I rolled off the throttle, it remained hung (did not accelerate). It would rev like usual, but had odd, inconsistent throttle-return response. I shut it off (kill switch/key) and then re-started. It did this for a few miles until I pulled off and restarted it again. All seemed well at that point. I was able to switch modes consistently. But 5 or so miles down the road, there was again an issue (mostly I noticed due to not being allowed to switch modes) which disappeared after restart. After that, it seemed fine until I went WOT and it kept 7K as I shifted. Subsequently, I rode it for about 30 minutes without any issue at all. I'm not sure what's going on.
I'm baffled and pissed. Bike is out of warranty and WTF is with a fly by wire system that won't shut off when you tell it to. What about redundancy? Anybody have ideas? Suggestions?
