Do the breather reroute mod -- many threads on here about it. I'm assuming it has a high flow air filter, ie k&n. If not, pop one of those in it. And other than safety checks like brake pads, brake fluid, good rubber, air pressure you should be able to ride it fine. Further maintenance I would check the primary chain adjustment and clutch cable adjustment. Have the battery load tested and clean all ground connections.
