(Feeler Gauge Procedure)
􀂄 NOTE: On the 400 VP, the seat assembly, side
panels, and gas tank must be removed for this procedure.
1. Remove the timing inspection plug; then
remove the tappet covers
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.
3. Using a feeler gauge, check each valve/tappet
clearance. 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.

4. Install the timing inspection plug.
5. Place the two tappet covers into position making
sure the proper cap screws are with the proper
cover. Tighten the cap screws securely.
! CAUTION
The feeler gauge must be positioned at the same
angle as the valve and valve adjuster for an accurate
measurement of clearance. Failure to measure
the valve clearance accurately could cause valve
component damage.
VALVE/TAPPET CLEARANCE (400/500)
Intake 0.05-0.10 mm (0.002-0.004 in.)
Exhaust (400) 0.22-0.27 mm (0.009-0.011 in.)
Exhaust (500) 0.17-0.22 mm (0.007-0.009 in.)

Forgot to tell you - take the spark plug out.

Just wondering how to set the valve clearance on a 03' 400 4X4 ? What is the valve clearance and where is the timing marks for TDC ? Do I have to take the fuel tank off or can I get to the valves without removing the tank ?
Thanks,
D.
