They smoke less ( a little) after you get them all warmed up and reved through the gears to "clean it out" If you are out for a family ride you dont need as much oil.  But if your wide open 6,8,10 seconds you need more. Impractical to switch back and forth and can affect jetting as well so I usually run 32:1 for most of my riding and yes it will smoke but  thats fine.  If i am going to be hammering it hard wide at the dunes i will go 24:1.   IF you get you a good castor bean oil and stand behind the exhaust while it idles a while you can close your eyes the next day and think your riding again by the smell all over your clothes.  My wife says I stink,,  I just call it    "MY 2 -Stroke MUSK"
