Valve adjustment
 

I went to do the valve adjustment and could not get the bolt in the back right off because it is covered by the wire harness arm above it. You can unclip the two sides of the wire harness arm but there is still a bolt that holds it in place on the opposite side. Is this the best way to go about the valve cover removal? Do I need to remove the wire harness arm or is there an easier way?
