A good place to start always is to give the bike a service. It is amazing how many problems are fixed by changing a plug, cleaning/replacing an aircleaner and doing an oil change. Never forget to go over the bike and ensure all bolts and nuts are correctly tightened especially on the sprocket and spokes.
You will need to determine what your jetting currently is before you start and where you feel it is not delivering the power. Get you idle mixture sorted after the service. If the idle screw is between 1 and 2 1/2 turns out it means your idle jet is close to start with. Clearly identify which model carby you have too as some have been replaced by previous owners.
