IMPORTANT NOTICE
This installation should be done by an experienced mechanic who has access to a factory service manual and all required tools. Measure flywheel pinion shaft run
out. Excessive pinion shaft run out will cause camplate and oil pump damage and or failure. Excessive pinion shaft run out will void manufacturer's warranty.
NOTE: HP+ & RACE SERIES pushrods can be adjusted 0.225" longer than stock to accommodate longer cylinders and smaller base circle camshafts.

CAUTION
Incorrect installation can cause engine damage not covered under warranty. Failure to install components correctly can cause engine seizure. Engine seizure may
result in serious injury to motorcycle, operator, passenger, and/or others. Removal of the rocker arms and or pushrods with the valve train loaded can damage rocker
arms, push rods, bushings and or camplate. Rotate engine to TDC of compression stroke on the servicing cylinder.

INSTRUCTIONS:

1.
Refer to the proper factory service manual for your model and year of engine, for removal of existing pushrods.
2.
The Feuling pushrods are designed with a small adjustment parameter for rigidity creating maximum lift – These are not quick install pushrods and
®
may require the removal of the lifter blocks and or loosening of the breathers/rocker arms supports. When loosening the rocker arm supports always
remove the breather bolts first and have the servicing cylinder on TDC.
3.
Clean and inspect each new Feuling
4.
Feuling pushrods are marked Intake and Exhaust. The shorter pushrods are Intake and the longer pushrods Exhaust.
®
5.
Feuling recommends using new O-rings and gaskets where applicable to prevent oil leaks.
®
6.
Always pump up hydraulic lifters before installing them. Use an oil squirt can to fill the lifter with oil through the feed hole on the side of the lifter,
push oil through the feed hole until the air bubbles are gone. If needed work the oil back and forth through the feed hole and pushrod seat with the
squirt can. Light weight oil can be helpful.
7.
Assemble and adjust one cylinder at a time, the servicing cylinder needs to be on TDC of compression stroke so the cam lobes and lifters are at their
lowest point.
8.
Install pushrods into proper locations with the adjusting side of the pushrod down, towards the lifter. Slide the pushrods through the pushrod covers
up into the rocker housing and set the pushrod on the seat of the lifter. We recommend filling the pushrods with oil then maneuver the pushrod up
into the rocker arm seat.
9.
Torque rocker arm housings and breathers to factory torque spec's.
10.
See the instructions for your lifters for the proper adjustment. All Feuling

on Feuling lifters from zero lash, 2.15 – 2.63 turns will put .090" – .110" of crush on the lifter. The loose jam nut tightens to the bottom.
• DISTANCE PER TURN = .0417"
• 2 1/8 - 2 5/8 TURNS = .090"-.110"
12.
We recommend starting from zero lash with a fully pumped up lifter and adjusting the
pushrod longer crushing the lifter. We DO NOT recommend bottoming the lifter and
adjusting backwards. To find zero lash it is best to have the rocker arm in hand to feel
and verify zero lash position.
13.
Wait for hydraulic lifters to bleed off before rotating engine over, this may take
10 – 25 minutes.
