Thats cool, Why so long on the choke? In my experience I only choke for less than a 1/4 mile or so on the 1300 and the 600 was just a touch longer if I pulled away from a cold start, most times that bike warmed up sitting still. These are with temps down to the freezing mark in the mornings, I don't ride (motorcycles) below 32 degrees. My Yamaha Kodiak 450 ATV doesn't like even a partial choke any longer than a minute or so, same with the wifes 250 ATV.
I really like your bike, sharp! Love that color combination. I am looking to pick up a 250 (or so) for the bride this year, she needs a low seat height so I've been checking out the Honda Rebels. The more I see of those 250 Ninja's though the more I like........
