I had what you describe happen on the way to work in the rain. Was able to limp to work and at the end of the day looked her over before trying to crank her. Somehow my right coil stick had popped up and wasn't fully seated. No idea how that happend as I hadn't done anything to her in a bit and she stays secure in a locked garage so no pranksters. Reached in and pushed it all the way down and she was good to go. It's worth a look. Good luck.
Ride To Live, Live To Ride....no, really!
