The bike is 9 months old and has 35 hours on it. I have never had any mechanical issues with it. All stock except for foot pegs and bar risers. I haven't ridden it in 2 months and took it to the track yesterday. Rode fine for 30 minutes. Then it started dying when I came to a stop with the clutch pulled in. Then it got worse where it would start and then die 10 seconds later. Is it possible that the gasoline went bad? My gas container has gas probably 3 months old. I filled it up while I was riding. Maybe the gas that was in it was OK, but as I added gas from the container, the proportion of bad gas increased making it run worse and worse? The other thing I noticed before having stalling problems is that the kill switch seemed like I had to push it down more to stop the engine, maybe the kill switch is going out. Any ideas?
