Motorcycle Mechanic Course

Lesson 1 • Tools and Equipment Identification

Introduces hand tools, power tools, and specialty motorcycle tools. Proper tool selection reduces component damage throughout the course.

Lesson 2 • Shop Safety and Personal Protection

Establishes safe work habits, PPE selection, and hazard recognition. Directly prevents injury during all hands-on lab activities.

Lesson 3 • Measurement and Precision Techniques

Covers calipers, micrometers, feeler gauges, and dial indicators. Precise measurement is required for engine and drivetrain tolerances covered later.

Lesson 4 • Service Documentation and Manuals

Teaches use of factory service manuals, wiring diagrams, and parts catalogs. Accurate documentation underpins every diagnostic and repair task.

Lesson 1 • Internal Combustion Principles

Explains thermodynamic cycles, air-fuel ratios, and combustion events. This theory supports accurate diagnosis in all engine chapters.

Lesson 2 • Two-Stroke Bottom-End Service

Addresses crankshaft, main bearings, seals, and case splitting procedures. Bottom-end integrity prevents catastrophic engine failure.

Lesson 3 • Two-Stroke Performance Diagnosis

Uses compression testing and leak-down analysis to locate power loss. Diagnostic skills developed here transfer directly to four-stroke diagnosis.

Lesson 4 • Two-Stroke Top-End Service

Covers cylinder, piston, rings, and reed valve inspection and replacement. Top-end condition directly affects power output and reliability.

Lesson 1 • Valve Train Components and Adjustment

Covers OHC and OHV configurations, valve clearance measurement, and shim selection. Correct valve timing maximizes compression and fuel efficiency.

Lesson 2 • Engine Assembly and Break-In

Guides complete engine assembly using correct torque values, sealants, and break-in procedures. Proper assembly prevents premature wear and warranty issues.

Lesson 3 • Piston, Rings, and Cylinder Service

Teaches bore measurement, honing, piston clearance, and ring gap setting. Proper fit prevents oil consumption and blow-by.

Lesson 4 • Cylinder Head Reconditioning

Addresses head removal, warpage checking, valve lapping, and reassembly torque sequences. Head integrity is critical for compression and coolant sealing.

Lesson 1 • Fuel Injection System Components

Identifies throttle body, injectors, fuel pump, pressure regulator, and sensors. Component knowledge is prerequisite for EFI diagnosis.

Lesson 2 • EFI Sensor Diagnosis and Service

Tests TPS, MAP, IAT, O2, and coolant temperature sensors using a multimeter. Sensor accuracy is essential for correct ECU fueling commands.

Lesson 3 • Carburetor Theory and Operation

Explains venturi effect, circuits, and jetting principles across slide and CV carburetors. Theory enables accurate circuit-level diagnosis.

Lesson 4 • Air Intake and Exhaust Systems

Covers air filter service, intake boot inspection, and exhaust system condition. Intake and exhaust restrictions directly affect power and fuel trim.

Lesson 1 • Ignition System Testing

Tests CDI, TCI, and coil-on-plug ignition systems for spark quality and timing. Ignition faults cause no-start and misfire conditions diagnosed in later chapters.

Lesson 2 • Lighting and Accessory Circuits

Diagnoses headlight, taillight, turn signal, and horn circuits using wiring diagrams. Lighting faults affect rider visibility and regulatory compliance.

Lesson 3 • Starting System Diagnosis

Diagnoses starter motor, solenoid, relay, and inhibitor switch circuits. Starting system faults are among the most common customer complaints.

Lesson 4 • Electrical Fundamentals Review

Covers Ohm's law, series and parallel circuits, and voltage drop concepts. Electrical theory is the foundation for all diagnostic procedures in this chapter.

Lesson 1 • CVT and Automatic Transmission Service

Services variator, drive belt, rollers, and centrifugal clutch on scooter-type CVT systems. CVT service restores acceleration response and fuel economy.

Lesson 2 • Clutch System Service

Covers wet and dry clutch disassembly, friction plate measurement, and spring tension testing. Clutch condition directly affects power delivery and rider control.

Lesson 3 • Belt and Shaft Drive Service

Inspects belt condition, pulley alignment, and shaft drive gear oil and backlash. Alternative final drives require specific service intervals and techniques.

Lesson 4 • Chain Drive Maintenance

Covers chain wear measurement, sprocket inspection, tension adjustment, and lubrication. Chain drive is the most common final drive requiring routine service.

Lesson 1 • Wheel and Tire Service

Covers spoke tension, rim runout, tire mounting, and inflation to specification. Wheel integrity is fundamental to safe motorcycle operation.

Lesson 2 • Front Fork Service

Covers conventional and inverted fork disassembly, seal replacement, oil volume, and spring preload. Fork condition governs front-end stability and braking.

Lesson 3 • Drum Brake and Steering Service

Inspects drum brake linings, wheel cylinders, and steering head bearings for wear. Steering and drum brake condition affect low-speed control and safety.

Lesson 4 • Hydraulic Brake System Service

Services master cylinder, caliper, brake pads, and fluid flush on disc brake systems. Hydraulic brake performance is the primary active safety system.

Lesson 1 • ECU Adaptation and Reflashing

Performs throttle position reset, idle speed adaptation, and firmware updates using manufacturer software. Correct ECU calibration restores factory driveability after repairs.

Lesson 2 • Live Data and Fuel Trim Analysis

Monitors short-term and long-term fuel trim, lambda, and injector pulse width in real time. Fuel trim data reveals air, fuel, and sensor faults without disassembly.

Lesson 3 • Oscilloscope Diagnostics

Captures injector, ignition coil, and sensor waveforms to identify intermittent faults. Waveform analysis detects failures invisible to static multimeter testing.

Lesson 4 • ABS and Traction Control Diagnosis

Tests wheel speed sensors, ABS modulator, and control module using scan data and wiring diagrams. ABS faults compromise braking safety and require systematic diagnosis.
