Controls and Operation Flashcards

What is the correct sequence for starting a motorcycle with a manual choke?

Answer: Open choke, start engine, then gradually close choke as engine warms

A cold engine needs a richer fuel mixture, so you open the choke to start and close it progressively as the engine reaches operating temperature.

What does the tachometer measure on a motorcycle?

Answer: Engine revolutions per minute (RPM)

The tachometer displays engine RPM, helping the rider know when to shift for optimal performance or fuel economy.

At what point in a turn should you gradually roll on the throttle?

Answer: After you have established your lean angle through the turn

Rolling on the throttle once lean angle is set stabilizes the suspension and helps the tires maintain traction through the curve.

What happens if you release the clutch too quickly when starting from a stop?

Answer: The motorcycle may lurch forward or stall

Releasing the clutch abruptly can cause the engine to stall or make the bike lurch forward dangerously.

What is the function of the fuel petcock (fuel valve)?

Answer: It controls the flow of fuel from the tank to the carburetor or fuel system

The petcock regulates fuel flow and typically has ON, OFF, and RESERVE positions.

What is the recommended technique for braking in a curve?

Answer: Straighten the motorcycle as much as possible before applying brakes

Braking while severely leaned reduces available traction for braking, so straightening the bike allows more braking force to be applied safely.

What does the term 'friction zone' refer to?

Answer: The range of clutch lever travel where the clutch begins to engage and transmit power

The friction zone is the clutch engagement range used for slow-speed control and smooth starts.
