• Turn ignition switch ON (with engine stopped). With fuel pressure applied to fuel piping, check for fuel leak-
age at connection points.
• Start engine. With engine speed increased, che ck again for fuel leakage at connection points.
• Run engine to check for unusual noise and vibration.
• Warm up engine thoroughly to make sure there is no leakage of fuel, exhaust gas, or any oils/fluids including engine oil and engine coolant.
• Bleed air from passages in lines and hoses, such as in cooling system.
• After cooling down engine, again check oil/fluid levels including engine oil and engine coolant. Refill to spec- ified level, if necessary.
• Summary of the inspection items:
*Power steering fluid, brake fluid, etc.

DISASSEMBLY
1. Remove spark plug using suitable tool.
2. Remove valve lifter.
• Identify installation positions, and store them without mixing them up.
3. Remove valve collet. • Compress valve spring with Tool (A). Remove valve collet witha magnet tool (B).
CAUTION:
Be careful not to damage valve lifter holes.
4. Remove valve spring retainer and valve spring.
5. Push valve stem to combustion chamber side, and remove valve. • Identify installation positions, and store them without mixing them up.
6. Remove valve oil seal using Tool (A).
7. Remove valve spring seat.
8. Remove valve seat, if necessary. • Bore out old seat until it collapses. Boring should not continue beyond the bottom face of the seatrecess in cylinder head. Set the machine depth stop to ensure this.

5. When the repair work is completed, return the ignition switch to the
″LOCK ″ position before connecting
the battery cables. (At this time, the steering lock mechanism will engage.)
6. Perform a self-diagnosis check of al l control units using CONSULT-III.
Precaution for Procedure without Cowl Top CoverINFOID:0000000005930985
When performing the procedure after removing cowl top cover, cover
the lower end of windshield.
Precaution for Drain CoolantINFOID:0000000005930986
• Drain coolant when engine is cooled.
Precaution for Disconnecting Fuel PipingINFOID:0000000005930987
• Before starting work, make sure no fire or spark producing items are in the work area.
• Release fuel pressure before disassembly.
• After disconnecting pipes, plug openings to stop fuel leakage.
Precaution for Removal and DisassemblyINFOID:0000000005930988
• When instructed to use special service tools, use the spec ified tools. Always be careful to work safely, avoid
forceful or uninstructed operations.
• Exercise maximum care to avoid damage to mating or sliding surfaces.
• Cover openings of engine system with tape or the equiva lent, if necessary, to seal out foreign materials.
• Mark and arrange disassembly parts in an organized way for easy troubleshooting and assembly.
• When loosening nuts and bolts, as a basic rule, start with the one furthest outside, then the one diagonally
opposite, and so on. If the order of loosening is specif ied, do exactly as specified. Power tools may be used
where noted in the step.
Precaution for Inspection, Repair and ReplacementINFOID:0000000005930989
• Before repairing or replacing, thoroughly inspect parts. Inspect new replacement parts in the same way, and
replace if necessary.
Precaution for Assembly and InstallationINFOID:0000000005930990
• Use torque wrench to tighten bolts or nuts to specification.
• When tightening nuts and bolts, as a basic rule, equally tighten in several different steps starting with the ones in center, then ones on inside and outside diagonally in this order. If the order of tightening is specified,
do exactly as specified.
• Replace with new gasket, packing, oil seal or O-ring.
• Thoroughly wash, clean, and air-blow each part. Carefully check oil or coolant passages for any restriction
and blockage.
• Avoid damaging sliding or mating surfaces. Completely remove foreign materials such as cloth lint or dust. Before assembly, oil sliding surfaces well.
• Release air within route after draining coolant.
• Before starting engine, apply fuel pressure to fuel lines with turning ignition switch ON (with engine stopped). Then make sure that there are no leaks at fuel line connections.
• After repairing, start engine and increase engine speed to check coolant, fuel, oil, and exhaust systems for leakage.
