Just curious what that is? Is that a special procedure? Were you back off the choke over a period of time? Or does it just mean that you turn the choke off slowly?
When I warm up my bike in the morning... I put the choke on. Start the bike up. Wait till the temperature is at 30 degrees. Turn the choke off. Wait for bike to reach 40 degrees. Drive off slowly. Wait for bike to warm up fully.
