Hi Mike, The bike starts up fine with no choke in this weather, maybe just a little lethargic for like the first second but then gets into a gentle plodding tickover, but on the odd occasion it struggles to start, taking a couple of presses of the button. I try to stop myself twisting the throttle (even a little) but yes a mental error lol, my old America used to thrive on a gentle twist as you fired her up. I find it hard not to on this bike!
