Valve/Tappet Clearance
To check and adjust valve/tappet clearance, use the
following procedure.
NOTE: The seat, left-side and right-side engine
covers, and gas tank must be removed for this pro-
cedure.
1. Remove the timing inspection plug and spark
plug; then remove the tappet covers (for more
detailed information, see Engine/Transmission -

2. Rotate the crankshaft to the TDC position on the
compression stroke.
NOTE: At this point, the rocker arms and adjuster
screws must not have pressure on them.
Feeler Gauge Procedure
Using a feeler gauge, check each valve/tappet clear-
ance. If clearance is not within specifications, loosen
the jam nut and rotate the tappet adjuster screw until
the clearance is within specifications. Tighten each
jam nut securely after completing the adjustment.
CAUTION
Failure to properly seat and align the filter element
may cause severe engine damage.
CAUTION
The feeler gauge must be positioned at the same angle
as the valve and valve adjuster for an accurate mea-
surement of clearance. Failure to measure the valve
clearance accurately could cause valve component
damage.
