RTT Motorcycle Maintenance & Safety Checks 5 — Questions and Answers
Question 1: What is the purpose of checking the motorcycle's side stand and center stand springs?
- To ensure they hold the required weight of the motorcycle
- To confirm stands retract fully and don't drag on the ground while riding (Correct answer)
- To verify the stands can support a passenger's weight
- Springs only affect ABS performance
Correct answer: To confirm stands retract fully and don't drag on the ground while riding
Stand springs must pull the stand fully up when retracted so it cannot drag on the road or drop unexpectedly during cornering.
Question 2: What does milky or frothy engine oil on the dipstick indicate?
- Oil is fresh from the factory and not yet broken in
- Water or coolant contamination in the engine oil (Correct answer)
- The oil is over-filled past the maximum line
- Oil additive packages are working correctly
Correct answer: Water or coolant contamination in the engine oil
Milky or frothy oil is caused by water or coolant mixing with the oil, often indicating a blown head gasket or internal coolant leak requiring immediate service.
Question 3: How do you check if a motorcycle's rear suspension linkage bearings are worn?
- Listen for creaking while the engine is running
- With the wheel off the ground, check for looseness or binding in the swingarm pivot and linkage (Correct answer)
- Check for rust on the spring coils
- Measure rear ride height with a passenger aboard
Correct answer: With the wheel off the ground, check for looseness or binding in the swingarm pivot and linkage
Lifting the rear wheel and checking for play or rough movement in the swingarm pivot and suspension linkage reveals worn bearings that affect handling.
Question 4: What should you inspect on the motorcycle's electrical connections to prevent intermittent failures?
- Only the battery terminals need inspection
- All connectors for corrosion, looseness, and damaged insulation (Correct answer)
- Electrical systems are sealed and require no inspection
- Only inspect wiring after a crash or water exposure
Correct answer: All connectors for corrosion, looseness, and damaged insulation
Corrosion, loose pins, and cracked insulation on any electrical connector can cause intermittent failures in lighting, ignition, and safety systems.
Question 5: What is the recommended action if you notice your motorcycle pulling to one side during braking?
- Apply more pressure to the opposite handlebar to compensate
- Do not ride until brake system and wheel alignment are inspected (Correct answer)
- Gradually increase brake pressure to equalize
- This is normal and requires no action
Correct answer: Do not ride until brake system and wheel alignment are inspected
Pulling to one side during braking indicates unequal brake force, a sticking caliper, or misaligned wheel—all of which require inspection before the motorcycle is ridden safely.
Question 6: How often should motorcycle coolant (antifreeze) be replaced?
- It never needs replacing in modern motorcycles
- Per the manufacturer's schedule, typically every 2 years or 24,000 miles (Correct answer)
- Only when it turns visibly dark or rusty
- Every 500 miles during break-in, then never again
Correct answer: Per the manufacturer's schedule, typically every 2 years or 24,000 miles
Coolant degrades over time, losing its corrosion inhibitors and freeze/boil protection, so replacement per the manufacturer's schedule (often every 2 years) is essential.
Question 7: What is the correct interpretation of a motorcycle battery that starts the bike fine but dies quickly when left unused for a week?
- Normal battery self-discharge rate
- Battery has significantly reduced capacity and likely needs replacement (Correct answer)
- The charging system is overcharging the battery
- Cold weather is temporarily reducing battery output
Correct answer: Battery has significantly reduced capacity and likely needs replacement
A battery that quickly loses charge when not in use has deteriorated capacity (often from sulfation) and should be tested and likely replaced to prevent being stranded.
