The charging system on the x440s is suposed to run the e start, efi, and, fuel pump, if it does not have enough voltage it may turn over and not start, i have put in a larger output stator in my bike ( to run heated grips)from the e model. It seems that my bike is starting much better than it ever has, even when the grips are noy in use, i think Cannondale should just upgrade to the `175 watt stator and a lot of starting problems will be solved. the factory rep told me that the standard stator will take 45minutes to fully charge, the 175 will take 10 mins, if i was buying a new bike i would ask that the dealer install this before delivery
