Last summer I had my bike serviced by a dealership including a new battery. I rode from the front range of Colorado to central Utah a couple of days later. All was well. Turned around to come home and took a path less traveled which included higher elevation and cooler temps. (as did crossing the continental divide in CO, which was done at highway speed) The first switchback I slowed down (let off all throttle) for on a gravel Forest Service road the bike stalled, it restarted fine. This continued until I dropped down and picked a state highway. At highway speed the bike ran fine, it stalled again at stop signs and as I rolled into a rest area. As the day warmed up the problem ceased, at about 83 degrees. (TMI maybe but just giving some background.) I thought this to be a sensor issue related to the temperature. The level of gas in the tank has no apparent effect on this issue. I got back home okay with the stalling reoccurring later in the day when the temps dropped. A few local rides since have dispelled the temperature theory. And, I have confirmed the tank level is a non-issue.
So, after reading some (a lot of) blogs and posts and talking to guys that I know that know motorcycles I decided a fuel pump replacement would be the cheapest fix-it-by-replacing parts remedy. Today's ride confirmed the problem still exists so I'll keep the OEM pump on my spare parts shelf. My thought was the next logical step would be the fuel control module or surrender and take it back to a dealership. This is what I know: it's not the temperature, the fuel level, the pump, starting the bike after turning on the key without letting the brainbox cycle through, shifting down multiple gears with the clutch pulled in when coming to a stop and since sometimes it sputters before it dies it would not be the kickstand safety switch. (I don't know if all of those would affect my bike but I've read a lot about stalling)
Any ideas??? This problem started at 15K+ miles. I'm the original owner (without enough time to ride), the bike has always been garaged, plugged into a battery tender and when I know it will sit through the coldest months of winter I use a fuel stabilizer. Operating temperature, fuel consumption and overall power and performance are totally normal, otherwise.
