So after the co to +12 my start ups still have moments when the bike won't restart. I was up in the desert over T-Day and it was on the colder side, 25 at night and mid 50's during the day. There were multiple time when I'd stop during a ride and it would still take 2-4 pushes of the button before the bike would fire up. Both stopping on purpose or stalling the bike. So basically I didn't notice any real different in how the bike acted before and after I adjusted the co to +12. Unfortunately I didn't try other settings.
