INSTALLATION
1) Thoroughly clean the cylinder head/cylinder head cover
mating surfaces using a degreasing cleaning agent.
2) Apply a bead [ø2.0 – 3.0 mm (ø0.08 – 0.12 in)] of the liquid
gasket (ThreeBond
®
#1280B or equivalent) to the cylinder
head/chain case mating surfaces and to the No.5 rocker
shaft holder as shown.
• Assemble the cylinder head cover within 5 minutes after
application of the liquid gasket. If it has been left for 5
minutes or longer, remove the old liquid gasket and apply
the liquid gasket again.
• Do not pour the engine oil in the oil tank at least 30
minutes after assembly.

3) Apply soapy water to the spark plug tube seal lip of the
cylinder head cover.
4) Install the cylinder head cover on the cylinder head by
aligning the spark plug tube with the spark plug tube seal.
• Check the spark plug tube seals for breakage and fatigue
when installing the cylinder head cover.
• After installation, check that the spark plug tube seals are
not turned up but they are set properly.
• Wipe up the oozing soapy water.
5) After installation, swing the cylinder head cover lightly to
make the head cover gasket fit on the cylinder head cover.
6) Install the six head cover washers and loosely tighten the
