Try adding pigments to the mix if the white smoke is too-annoying. I suggest a nice mauve, or perhaps a bright tangerine.

Crankshaft seal, clutch side. Does the bike consume transmision oil? Also might be a coolant leak into the cylinder head (more steamy than smokey). Rodents might have made their way into the reed valve assembly, and chewed up all the stuff, so check that too.

I'm more a fan of taupe than mauve. It all comes down to personal preferences though...

What he said. White smoke is usually steam from the coolant entering the combustion chamber.
