Now I saw this twice, just after fitting the PowerCommander, always coming to a stop and pulling the clutch. I checked my throttle sensor and injector connections and it's not happened since. I put it down to an iffy connection (and it was well below 0c when I done the work).
It's not happened again, so I'm happy with the iffy connection prognosis.
I have in the past suffered this on older bikes and it's always been down to the sidestand switch, quick chop and it's sorted!
