When i start up my bike i have white smoke coming out. I also noticed i had black oil spraying out at the base of the muffler. Any idea whats happening and how to fix it?

White smoke is burnt oil; black oil at the base of muffler is unburnt oil.

Suggests, without further info and model/mileage information, serious valve stem problem or broken piston rings.

Any rattles in the motor?

Any recent performance drop?
