You want to set valves when both cams are all the way down. Easiest way to get that is to turn the engine to TDC on the compression stroke.
I cant hardly get thru my head that this is a dual cam engine. Im thinking the cams would be across left to right but they are front to back I guess. Weird, at least to me cause I think of DOHC on a big motorcycle engine like a 900 cc Kaw that I would watch my older buddies work on when I was a kid.
Ending my usual rambling, So when I manually turn it over as soon as the mag snaps I then gauge them both or do them individually as it snalp?
Im glad I stopped and got on here and posted because the ex side bolt or lifter was getting loose and if that would have somehow came out ( assuming it can ) I wouldnt have known what to do.
Thanks as usual
