Valve/Tappet Clearance
To check and adjust valve/tappet clearance, use the fol-
lowing procedure.
NOTE: The seat assembly, side panels, and gas
tank must be removed for this procedure.
1. Remove the timing inspection plug; then remove the
cylinder head cover (see Engine/Transmission -
Removing Top-Side Components).
2. Remove the outer magneto cover from the right side;
then remove the oil through and spring.

3. Using a socket and ratchet on the flywheel nut, rotate
the crankshaft so the “T” mark on the flywheel aligns
with the index mark on the right-side crankcase
cover.

NOTE: At this point, the round hole in the camshaft
gear should be up.
4. Check intake and exhaust tappets for proper clear-
ance using an appropriate thickness gauge. If clear-
ance is within specifications, proceed to step 7.
NOTE: Refer to the appropriate specifications in
Engine/Transmission for the proper valve/tappet
clearance.
5. On the tappet to be adjusted, loosen the jam nut; then
using Tappet Adjuster, turn the tappet to obtain the
specified clearance (clockwise to decrease, counter-
clockwise to increase).

6. Holding the tappet adjuster at the proper clearance,
tighten the jam nut securely; then recheck tappet
clearance.
7. Place the cylinder head cover with a new O-ring into
position; then tighten the cover securely.
