To me it sounds like a fuel management issue. You're choke/fuel enricher may be stuck in the on position, or you are running rich for some reason.

Could you tell us about any mods you might have on the bike? Is it the top or bottom pipe that the smoke is coming from?

Ant mods to the bike.
We need all info on the bike in order to diagnose it.
A/f is set too lean - should be set at 2.5 turns.

+1 knowing whats been done to it is the key to getting you running right, but 99% of the time if you have black smoke full time the choke isn't all the way in. If it feels like it is all the way in take a look at the carb to make sure the rubber boot is on correctly, if it's not it can hold the choke open a touch.
