how do you remove the rockers off a 2007 yfm 80? mine warped the exuast valve and damaged the head and the piston. i purchased a "cylinder head assembly" new from bikebandit.com but it was just the head, no rockers, no cam.... i need to get the rockers out of the old one. any one know how to?

 

Pull off the cam gear you should see 2 holes that should have threads in them bout the size of your pinky i would say. Thread pitch is i think 6mmX1.0 you need a longer bolt to put a slide hammer on. thread the bolt in and hammer/pull the pin out and the rockers should fall out.
