keep the battery in good charge. i run 10w30 in the winter and it helps. and i also take a milkhouse heater and prop it up on the left foot rest facing towards the engine and drape a tarp or small blanket over the hood and other side of engine. only takes about fifteen minutes for it to warm up enough to start easily. and that is in about ten degree weather. thats in the garage too. since yours is outside, a breeze blowing could push some of the heat out of the engine compartment so more tarp coverage on both sides fo engine except over the back of the heater should work just fine.
