We need more information.  Has the bike been properly warmed up?  What remix are you runnung, and at what ratio.  If the smoke is white, it may be a bad crank seal that's allowing gear lube into the combustion chamber, check the gear oil level.  Another option is to check the fluid level of the raditors.  Are you sure its white smoke, and not steam?.
