C. 0.6–0.8 mm g
D. 1.0–1.2 mm g
Rationale: Most motorcycles require a spark plug gap of 0.6–0.8 mm
g g g g g g g g g g
gto ensure proper ignition and efficient combustion.
g g g g g g
3. Which component controls the mixture of fuel and air in a carbureted
g g g g g g g g g g g
gmotorcycle engine? g
A. Fuel injector
g
B. Carburetor
C. Ignition coil g
D. Throttle cable g
Rationale: The carburetor mixes the correct ratio of fuel and air for
g g g g g g g g g g g
gcombustion in the engine. g g g
4. What is the function of the flywheel in a motorcycle engine?
g g g g g g g g g g
A. To increase fuel efficiency
g g g
B. To maintain engine momentum between power strokes
g g g g g g
C. To start the engine
g g g
, D. To regulate oil flow
g g g
Rationale: The flywheel stores rotational energy to smooth out the
g g g g g g g g g
power delivery from the engine.
g g g g g
5. What type of oil is commonly used in a wet-clutch motorcycle?
g g g g g g g g g g
A. SAE 10W-30 automotive oil

superior stopping power and control.
g g g g g
8. What is the correct procedure when measuring valve clearances on a
g g g g g g g g g g
four-stroke engine?
g g
A. Measure with the engine running g g g g
B. Measure with the engine cold and valves closed g g g g g g g
C. Measure with the engine hot and ignition on g g g g g g g
D. Measure with the carburetor removed g g g g
Rationale: Valve clearances must be measured when the engine is
g g g g g g g g g
cold to avoid thermal expansion affecting the measurement.
g g g g g g g g
9. What does a motorcycle’s CDI (Capacitor Discharge Ignition) unit do?
g g g g g g g g g
A. Controls fuel injection g g
B. Controls ignition timing g g
, C. Regulates battery voltage g g
D. Opens and closes valves g g g
Rationale: The CDI controls the timing and firing of the spark plugs
g g g g g g g g g g g
g to ignite the fuel-air mixture.
g g g g
10. Which type of suspension is commonly used on the rear of most
g g g g g g g g g g g

Rationale: The swingarm with shocks is standard on most
g g g g g g g g
g motorcycles, providing stability and comfort. g g g g
11. When replacing a motorcycle chain, what should be checked to
g g g g g g g g g
g ensure proper installation?
g g
A. Engine compression g
B. Chain tension and alignment g g g
C. Brake fluid level g g
