Maintenance, Inspection, and Repair Procedures
Domain focus
This domain covers scheduled maintenance, pre-ride inspection, diagnostic process, repair quality, documentation, and road testing. The exam tests whether you can turn a customer complaint into a verified repair and whether you catch safety items during routine service.
Core rules
- Follow the manufacturer's service schedule for oil, filter, air filter, valve clearance, coolant, brake fluid, chain, tires, bearings, and fasteners. Intervals may be distance-based, time-based, or both.
- A pre-ride inspection includes tires and pressure, controls, lights, horn, mirrors, fuel level, oil level, coolant, brake operation, chain or belt condition, and leaks.
- Use a consistent diagnostic process: verify the complaint, gather information, inspect, test, repair, and verify with a road test. Record measurements before and after.
- Use the specified oil and filter. Automotive oils with friction modifiers can cause wet-clutch slip. Replace crush washers and O-rings where specified.
- Torque fasteners to specification and use the correct sequence. Check safety items such as tire date, brake pad thickness, brake fluid condition, and steering head play.
- Document the complaint, cause, correction, parts, measurements, and road-test result. A repair is not complete until it is verified.
Worked example
A motorcycle arrives for a 12,000 km service. The technician changes engine oil and filter, replaces the crush washer, torques the drain bolt, and checks for leaks after running the engine. The air filter is inspected, valve clearance is measured and adjusted if needed, coolant and brake fluid are tested, the chain is cleaned and adjusted, and tire pressures and dates are recorded. The steering head is checked for play, fasteners are torqued, and the service reminder is reset. A road test confirms braking, shifting, and handling before the bike is returned.
Traps
Overfilling engine oil; using automotive oil with friction modifiers in a wet clutch; reusing a crush washer; skipping tire date checks; ignoring brake fluid moisture; adjusting valves without recording clearance; returning a bike without a road test; and assuming low mileage means no time-based service is due.
