MY '03 LT rarely smokes and I use the side stand all the time. I just turn off the key and watch the temp gauge slowly turn down to the rest position. Not sure how many seconds it takes to do that, but it's enough time for the oil to run out of the cylinder and back into the oil pan before I lean it over on the side stand. Just don't be in a big hurry to lean it over after you shut her down.
Also, make sure you don't add enough oil to make it over full. I never add any oil in between oil changes.
By the way, a little smoke at start up is no big deal. Just a little embarrassing if you're around a group of Harley's. LOL :bmw:
