Hi Guys, I was going to check the valves on my 1999 WR400F this weekend when I ran into a little bit of a problem. It looks like the nut had been rounded off and the PO attempted to grind through it, but to no avail. Any suggestions on how to extract the bolt? The allen head is a little stripped as well. Or if there are any tricks to removing the head without removing that motor mount I'm all ears!
