kawi fd731v. Worst valve adjustment I've ever done. Its all easy to get to. Easy to find tdc. Its the actual adjustment that is hard. There is a bolt that goes thru the rocker arm with a cam style bushing in between. You spin the bolt which spins the cam, which tightens or loosens the rocker arm on the valve. The problem is when you tighten it down it either loosens or tightens past the .006. It was close several times, but I dont do close. I'm ocd so someone else may not be as precise as me? Another thing. All valve adjustments I've done before, and I've done alot, always have a range. Like .005 to .007. Why not this motor? I dont know. I'm just complaining.
