Good News: The 3X stalling was traced to the sidestand switch. The bike has flawlessly since then..until Friday.
Bad news: I put a brand new battery in Thursday (should not be related), drove it to work and was heading home when I was coming up a hill and got that "something does not feel right" sensation. When I rolled off the throttle as I crested the hill the bike died FI light on. Light stayed on for would not start. After about 5 seconds the light went out, I could start it. Drove a few more hundred yards, cut out again. I managed to limp it to a friend's house and came back the next day to troubleshoot.
Next day, like others have noticed, no codes. Got it running and started to drive it again, still cutting out. This time I kept it moving, if revs/speed was low it would cut out, FI light on and kick back to life after a few seconds.
Once I got out on the highway I was able to keep it from cutting out (no FI light either) but it had that "something does not feel right" sense the whole way similar to what started the whole thing.
One more thing: Both turn signals were not blinking and would come on solid but dim. I was able to make it home, had to stop 100 feet from my house and it would not restart. Pushed it into the driveway. With the ignition on I could hear the turn signal relay "buzzing" if actuating either L or R turn signal. Unplugged the relay and checked the voltage on the plug: Oddly I was reading ~3V on the green.
After the first time this happened, I pulled every connector apart in the harness (including the (3) junction blocks wrapped up in the loom) cleaned and dielectric greased them. Checked every sensor per the manual (that I could without the break out box) all good, I could find no corrosion, burning, or any of the usual suspects something is bad. Checked the TPS which initially showed a "blip" with a digital VOM, I could not duplicate it with a analog VOM so it may have just been the meter.
This weekend, I took the bike apart again and checked the two mid harness blocks because I remember one had all the grounds and I suspected there might be a backfeeding involved, again found nothing. However, once I taped everything back up again, the turn signals were working. Voltage on the green was now a fraction of a volt. Maybe I should do the "Loom fix" even though there is no obvious problem?
So my question for my fellow sufferers is has their turn signals been part of their symptoms?
So my go forward plan would be to do the loom fix on all (3) blocks just to get them off the list (Part of my concern is the more I man-handle the harness, the more likely I am to create a problem as much as fix it). After that is a new ECU the likely problem? PS I have HID lights on my bike, someone suspected that could have caused a surge to the ECU and damaged it. My thought is that if it had, would it not be all the time or not at all? This type of issue seems to be more a like bad connection than anything.
Thanks for any ideas of what to do next.
