There are some things that might help;
For cold starting, it helps if you turn on the ignition for a few seconds (till the fuel pump stops running) switch off then repeat, then try starting it.
S&S recommend 10/40 oil for low temperature use rather than the 20/50 that is normally suggested for the X-Wedge. This will reduce the load on the starter motor and battery a bit.
The battery needs to be kept topped up - assuming you are getting the same battery that we do anyway. Quite a few people seem to find the standard battery a bit marginal, might even be worth changing to a battery with a higher cold cranking capacity.
Coldest I've started mine is about -5°C so can't say for sure that any of the above will work.
Another couple of thoughts; if this has been a bit of an only one car problem then check that the regulator rectifier is actually working and the battery is being charged, and also remember that the alternator is a bike type unit so can run out of amps to charge tha battery if it is being run with all lights, heated seats, heated clothing etc.
Also a possibility would be a failing fuel pump; check the pressure at the Schraeder valve on top of the throttle bodies, it should be 58psi. If it's low then pump itself could be on its way out or the fuel filter could be clogged and the mixture might be a bit lean for cold starting.
Best of luck.
