Haha, not exactly. If the bike bogs down when I start it or if it bogs down when I get in gear, then I add some choke, enough to bring it close to 2k. Then I just ride like normal for the next bit, shut the choke off when I can. The airflow thing is iffy, especially if you consider our bikes are part liquid cooled, but who knows. This was just my understanding of it (not to leave the bike warming up for more than a minute, really). Perhaps I'm doing it all wrong!
Usually my 'warming up' takes 15-20 seconds tops.
