Red Seal Motorcycle Technician Practice Exam

What should you do if you hear unusual noises from the motorcycle engine?

1. Ignore them until the next service

2. Investigate immediately; it could indicate serious mechanical issues

3. Check the tire pressure

4. Increase the fuel grade being used

The correct answer is: Investigate immediately; it could indicate serious mechanical issues

Hearing unusual noises from a motorcycle engine is a sign that something may not be functioning correctly. Investigating immediately is crucial because these noises could indicate serious mechanical issues, such as misalignment, bearing failure, or problems with internal components like the timing chain or valves. Promptly addressing these concerns can prevent further damage, ensure rider safety, and potentially save on costly repairs. Other options, such as ignoring the sounds or focusing on tire pressure, do not address the immediate concern of engine health. While checking tire pressure is important for overall motorcycle maintenance, it is not directly relevant when unusual engine noises are present. Similarly, increasing the fuel grade may not solve an underlying mechanical issue and can be misleading in the context of engine sounds. Therefore, taking immediate action to investigate unusual noises is essential for maintaining the motorcycle's performance and safety.
