Note: You can check your adjustment for all 4 tappets by performing the following: With
the rear wheel safely off the ground (bike tied down), shift bike into the highest gear, have
a helper rotate the rear tire forward just enough to see the front intake tappet start its
move up in its bore (only allow the tappet to move up it’s bore .100”, almost the thick-
ness of a nickel). Stop the rotation of rear tire and have helper rotate the rear tire back-
ward just enough to see the front intake tappet start the movement back down and then
back up it’s bore no more then .100”. As the tappet is moving up and down in it’s bore
(from the rear tire being rotated back and forth) you will need to be trying to turn that
pushrod with your thumb and forefinger. If you find any free movement (turning) of the
pushrod, take up this freeplay (by making the pushrod longer with the adjusting screw)
until you can barely turn the pushrod with your fingers.
Do the above Note for the other 3 tappets.
6. Repeat exact procedure for the next three pushrods, making sure to be on the
lowest position of cam for the tappet you're adjusting.

1. New motors, after the first 50 miles (at time of first oil change), check adjustment
of pushrods. You should still be able to turn them with your fingers, if not, you will
need to loosen the pushrod until it can be moved.
2. After 200 miles, readjust if needed and as needed until all your motor parts are seated.
3. Recheck as
you would
for solid
tappets,
at about
2,000
mile
intervals.
