Well, I was not able to ride the bike for about 4 days due to bad weather/tropical storm moving through the area. Went out to ride, perfect day, but the bike ran like shit. I turned it on to warm it up, the rpms were fluctuating and never got above 1k. After about 20 seconds of running, it shuts off completely. Now, I can only get it started for about 2 seconds. It's an '05 636 with about 3500mi on it and had never had any problems in the past. Anybody have any ideas of what might be wrong?
