Belt drive is quieter, but can be damaged by stones caught between belt and sprocket.
You can change the chain sprockets of most motorcycles to get a higher top speed. Reduce the rear sprocket numerically, and/or increase the front sprocket numerically. A higher profile tire will also increase top speed slightly.
The chainring by the pedals and the sprocket(s) by the rear wheel.
Normally that indicates a worn out sprocket. Replace and you should be OK.
