Jetting - About the needle

I wouldn't think the jetting would cause this sudden burst of smoke because riding the bike very slow for 1 minute or so will load it up and cause more oil buildup in the combustion and when you crack that throttle the RPMs go up causing the combustion to clean out that extra oil it loaded up on. If the jetting feels alittle rich or lean on the needle then change it around but if it runs crisp on the needle but with that little amount of smoke then messing with the needle won't really help. Differents 2-strokes oil will smoke more hten others and some will not smoke at all (Maxima SuperM never smoked for me). I am now running a Castor oil (Klotz BeNOL) and I get some smoke so I have understood it is not a jetting issue more of a oil issue.
