I try to start my bikes at least once a week. Only time they sit for a week without riding is in the cold and rainey part of out Texas winters. Started both once when it was about 25F in an unheated garage. The America took a few spins at full choke, about 10 seconds, and the SM (carb. set up much more rich) started right up in a couple of turns. I let the carb heater go for about 10 to 15 seconds before hitting the starter on those days below 35 or so. My SM loves the cold, I suppose thicker air to match the more gas, The America likes the cold after she warms up, but the Speedy really excells when it's cold, They are British after all.
