Honestly, I’ve never had to actually use the choke (which is part of my confusion over it). Generally I store it in the garage, so ambient temp is high 50s – low 60s. I haven’t had any trouble starting it cold.
Yes, the S40 is my first bike. I took the MSF in July and bought the bike in late August. I had a rough start, but it has been a pleasure to ride since I got over the hump.
