Valve Clearance Adjustment - Kawasaki KX450F Service Manual

Hide thumbs


Periodic Maintenance Procedures
First, bring the piston to the top-dead-center of its com-
pression stroke to inspect the valve clearance (the posi-
tion at the end of the compression stroke), when the cam
lobe faces outside of the camshaft.
Place a wrench over the balancer weight nut and turn
it counterclockwise to align the TDC mark [A] with the
center of the groove [B] of the inspection hole.
Using a thickness gauge [A], measure the clearance be-
tween each cam lob and valve lifter for all four valves.
For the purpose of adjusting the valve clearances, record
the measured values.
Valve clearance: between cam and valve lifter
0.17 ∼ 0.22 mm (0.0067 ∼ 0.0087 in.)
0.10 ∼ 0.15 mm (0.0039 ∼ 0.0059 in.)
If the valve clearance is not within the specified range,
adjust it.

Valve Clearance Adjustment

Remove the camshaft caps [A] (see Camshaft Removal
in the Engine Top End chapter).
Remove the camshafts [B] (see Camshaft Removal in the
Engine Top End chapter).
Remove the valve lifters [C] of the applicable valve.
Remove the shim [D] from the top of the spring retainer.
Mark and record the locations of the valve lifters and
shims so that they can be reinstalled in their original
