Listen to the engine for excessive noise. Check the oil to see what condition it is in. Check the air filter. Take the air filter off if the owner will let you. Look for dirt in the snorkel tube. Ask a TON of questions about maintenance, known problems,upgrades, who did the work. Just try and get as much history on the bike as possible. And of course ride it. Ride it easy then rip on it a bit.
