Troubleshooting Guide
Air cleaner duct loose
Compression low:
Spark plug loose
Cylinder head not sufficiently tightened down
No valve clearance
Cylinder, piston worn
Piston ring bad (worn, weak, broken, or sticking)
Piston ring/groove clearance excessive Cylinder head warped
Cylinder head gasket damaged
Valve spring broken or weak
Valve not seating properly (valve bent, worn, or carbon accumulation on the seating surface)
Other:
IC igniter in ECU trouble
Throttle body assy not synchronizing Engine oil viscosity too high
Drive train trouble
Brake dragging
Air suction valve trouble
Vacuum switch valve trouble
Engine overheating
Clutch slipping
Poor Running or No Power at High Speed:
Firing incorrect:
Spark plug dirty, broken, or maladjusted Stick coil wiring trouble
Stick coil not in good contact
Spark plug incorrect
Camshaft position trouble
IC igniter in ECU trouble
Crankshaft sensor trouble
Stick coil trouble
Fuel/air mixture incorrect:
Air cleaner clogged, poorly sealed, or missing
Air cleaner O-ring damaged
Air cleaner duct loose
Water or foreign matter in fuel
Throttle body assy holder loose
Fuel to injector insufficient (DFI)
Fuel tank air vent obstructed
Fuel line clogged
Fuel pump trouble (DFI)
Compression low:
Spark plug loose
Cylinder head not sufficiently tightened down
No valve clearance
Cylinder, piston worn
Piston ring bad (worn, weak, broken, or sticking)
Piston ring/groove clearance excessive Cylinder head gasket damaged Cylinder head warped
Valve spring broken or weak
Valve not seating properly (valve bent, worn, or carbon accumulation on the seating surface)
Knocking:
Carbon built up in combustion chamber Fuel poor quality or incorrect
Spark plug incorrect
IC igniter in ECU trouble
Camshaft position sensor trouble
Crankshaft sensor trouble
Miscellaneous:
Throttle valve won’t fully open
Brake dragging
Clutch slipping
Engine overheating
Engine oil level too high
Engine oil viscosity too high
Drive train trouble
Air suction valve trouble
Vacuum switch valve trouble
Catalytic converter melt down due to muffler overheating (KLEEN)
Overheating:
Firing incorrect:
Spark plug dirty, broken, or maladjusted Spark plug incorrect
IC igniter in ECU trouble
Muffler overheating:
For KLEEN, do not run the engine even if with only one cylinder misfiring or poor running (Request the nearest service facility to correct it)
For KLEEN, do not push-start with a dead battery (Connect another full-charged battery with jumper cables, and start the engine using the electric starter)
For KLEEN, do not start the engine under misfire due to spark plug fouling or poor connection of the stick coil
For KLEEN, do not coast the motorcycle with the ignition switch off (Turn the ignition switch ON and run the engine)
IC igniter in ECU trouble
Fuel/air mixture incorrect:
Throttle body assy holder loose
Air cleaner duct loose
Air cleaner poorly sealed, or missing Air cleaner O-ring damaged
Air cleaner clogged
Compression high:
Carbon built up in combustion chamber
