At 9k the stock bike is real rich. 1 washer does nothing much at 9k. 2 washers and snorkel removed makes the bike run better at 1/4-3/4 throttle. Depending on the thickness of your washers you may be able to do 3. Replace your stock filter with something like Pipercross, WIX or UNI. These filters utilize the frame of the stock air filter and tend to slightly improve performance.

As far as the spark plug being white, you should be fine. A grayish-white looking plug is normal. You probably don't have a enough miles on the bike for any significant carbon build up. Not only that, you maybe running at an optimum level that your fuel is burning efficiently. Burning away all deposits and showing a clean plug is a good (up to a point).
