I would have to say that is certainly not normal. Someone with a bit more experience should chime in soon.. good luckAt start up I have a little oil splatter coming out of the big radius pipes and speckling the garage floor. Is this normal or is this a carb problem.
Taste it!!good point BBc, if you're not smoking and not using oil then it could just be moisture. try and feel the "oil splatter" and see if it feels "oily" or not.
