I have a 2005 when I let the clutch out to take off the RPMs start sounding a little rough kinda chattering and blows some of the white/blueish mixture smoke. And when Im revving it up it kinda wants to miss in the higher RPM range then puffs a little more white. Coolant is good, oil is good, Im leaning towards starving for fuel/air? or possibly a timing issue on my smarty. I have a smarty, airdog 165 , cold air intake with AFE intake and filter and head studs.
