For more overall power you would need a bore and/or a stroke kit, if there is one available. A exhaust and a air filter along with a rejetting would give you a little boost.

Cheapest and easiest would be new sprocket sizes. A smaller rear sprocket will give you more top end speed, but you will lose alot of your acceleration. A larger rear sprocket will give you quicker acceleration, but lower top end speed. If you go this route you will need a new chain
