I have an '07 FXSTBI Night Train. I moved up here to the Philadelphia area a little over a year ago. I have never had a problem starting my bike before, but then again, Ive never had to start one in freezing or near freezing temps..haha. My charging system is good, however I probably could use a new battery, but last year it was just fine. As it is coming up on the winter months and my bike is all I have (or want for that matter....33,791 miles on her now) I need to make sure the problems I had last year wont happen this year. Anyway, my scoot will turn and turn but not start when it's this cold. I though about the fuel lines freezing, but had added Heat to it last year...I though that , the oil may be too thick, but it turns, so obviously thats not the problem....I am 35 and at a very young age was taught Fuel, Spark, and Air. OK, now the filter is clear and fine, valves are opening and closing and all that. Spark is fine, I'm assuming, because it only happens when its near or freezing...and there is power to run everything and so forth, so that leads to fuel. Its obviously injected, so there is pressure, and I've read that lines in injected vehicles dont freeze due to that. Also, I know Ethanol (which is unfortunately at every gas pump...haha) absorbs moisture and makes Heat or Drigas obsolete...all things Ive researched...maybe the vents in the gascap are clogged with ice? I'm at loss here...any help is much appreciated!!!
