Add a tank of fresh gas with a double dose of SeaFoam or Regain (like 2 oz/gal or even a tad more), run motor for 10 min, let sit overnight to a day or two, start it up and ride bike till most of the gas is used up. Repeat if needed.
I prefer SeaFoam, and have run it in very strong mix (more than 3 oz and 1 gal of gas) the bike will smoke a bit, and the exhaust will smell funny but in many (most) cases this will solve the problem after a tank or two of gas.
I normally add a shot SeaFoam every second or third fill up, and always if I put the bike up for longer than a week or two.
