In order to set the lifter preload, the lifters must be on the base circle of the cam lobes. Find zero preload by up and down movement of the pushrod before adjusting 1/2 to 3/4 turn.
First, get a small artists paint brush and white paint. Mark off the harmonic damper in quarters from 0 timing mark, #1 piston TDC on compression stroke.
#1 TDC...........set int. / exh. on #1
1/4 turn CW....set int. / exh. on #8
1/4 turn CW....set int. / exh. on #4
1/4 turn CW....set int. / exh. on #3
Continue 1/4 turn and set preload in that manner according to the firing order. That will guarantee the lifters will be on base circle (overlap) of cam lobes when they are adjusted.
Firing order: 1 8 4 3 6 5 7 2.
