Warm-Up proceedure?

[GoldOxide_imp]

A CB1100 cold start-up will handle anything I threw at it. Maybe with -25C ambient air temperature, it could take two or three (instead up to one) major intersections before idle would settle back to the popgun standard.

In fact, if I ever had trouble maintaining CB1100 idle, it would be on the really hot, humid days after stopping at a gas station to refuel after a long ride. Sometimes the engine needed a little throttle finesse to keep from stalling.

Gold...are you saying this happened periodically?

I would say almost every time after a long, hot and humid ride, particularly getting off the freeway (maybe after 75 to 90 minutes of freeway droning) and refueling, and then resuming the ride.

During the engine restart, the engine struggled with the fresh, cold fuel. Blipping the throttle - which was typically unusual for the mighty inline-4 - was required to maintain minimum idle RPM.

I never thought much about it to be honest and reckon it was par for the course under those conditions. There was no misfiring or rough idle and once in motion, it was like nothing happened.
