If it really bugs you just leave the choke out. I forgot to push it in once and wondered where the popping sound was until I realized I'd forgotten to push the knob back. (on a long days highway riding, I went over 100 miles with the choke knob out)
The advantage to our bikes is that it is not really a choke so it didn't stall the bike once it warmed up. It's just like having REALLY rich idle jets. You'll burn a little more gas but otherwise it didn't seem to affect performance except it idles really fast and you don't decelerate much at idle.
