2-20 PERIODIC MAINTENANCE
Periodic Maintenance Procedures
Evaporative Emission Control System Inspection
(SEA-B1 and TH Models)
Inspect the canister as follows.
Left Frame Cover (see Frame Cover Removal in the
Canister Bracket Bolts [A]
Unhook the band [B] to remove the canister [C], and dis-
connect the tubes [D] from the canister.
Visually inspect the canister for cracks or other damage.
If the canister has any cracks or bad damage, replace it
with a new one.
The canister is designed to work well through the motor-
cycle's life without any maintenance if it is used under
Inspect the purge valve (see Purge Valve Inspection in
the Fuel System (DFI) chapter).
Check that the hoses are securely connected and clips
are in position.
Replace any kinked, deteriorated or damaged hoses.
Run the hoses according to Cable, Wire, and Hose Rout-
ing section in the Appendix chapter.
When installing the hoses, avoid sharp bending, kinking,
flattening or twisting, and run the hoses with a minimum of
bending so that the emission flow will not be obstructed.
Coolant Level Inspection
Check the level when the engine is cold (room or ambi-
Check the coolant level in the reserve tank [A] with the
motorcycle held perpendicular (do not use the sidestand).
If the coolant level is lower than the "L" level line [B], re-
move the right center fairing (see Center Fairing Removal
in the Frame chapter), unscrew the reserve tank cap, and
add coolant to the "F" level line [C].
For refilling, add the specified mixture of coolant
and soft water.
coolant and degrades its anticorrosion properties.
The diluted coolant can attack the aluminum en-
gine parts. In an emergency, soft water alone can
be added. But the diluted coolant must be returned
to the correct mixture ratio within a few days.
If coolant must be added often or the reservoir tank
has run completely dry, there is probably leakage in
the cooling system. Check the system for leaks.
Coolant ruins painted surfaces. Immediately wash
away any coolant that spills on the frame, engine,
wheels or other painted parts.
Adding water alone dilutes the
