I'm inclined to agree with XTorange's post. Especially if you have over filled your oil tank. The clue is in your assessment that it smokes for 2 -3 minutes. If it were valve stem seals you are more likely to find that it smokes really badly for about 20 seconds at most. Really just a big puff before clearing up. If you have overfilled on oil, crank case pressure will build and blow excessively back into the airbox. This is exacerbated by the common failing of the oil stop valve (ball and olive affair next to the oil filter) allowing excessive oil to pool in the crank case overnight rather than retaining it in the oil tank.
Check your oil tank level after parking up overnight before switching on the engine. If it shows to be low by comparison after running for a minute or two you will have an strong indication that this may well be the case.
