what he said...
3-4 heat cycles... let it idle for 10-15 min.. let cool for 30-45 mine, after 1st or second cycle let it cool and check your head bolts.
after that.. ride it... start out idle to 1/4 throttle.. varrying the throttle dont hold it at one set throttle limit..... let it cool than half throttle.. let it cool 3/4 let it cool full.. allways vary the throttle
