Too rich or lean.

Look at the plugs and do a search on this site....there are some plug "color" guides that will help you determine whether you are too rich or lean. Mixture is adjusted by moving the needle inside the sliding cylinder in the neck of the carb. Good luck

Also you might wanna adjust your valve clearances and cam chain. Both are easy adjustments.
