Motorcycle Repair Course

Lesson 1 • Service Documentation and Manuals

Teaches how to read OEM service manuals, wiring diagrams, and torque specification tables. Accurate documentation use is the foundation of systematic diagnosis.

Lesson 2 • Fasteners, Threads, and Torque Principles

Explains bolt grades, thread types, and the physics of proper torque application. Students avoid stripped threads and fastener failure in all future repairs.

Lesson 3 • Workshop Safety and Tool Orientation

Covers PPE requirements, fire prevention, and chemical handling in a shop setting. Connects safe habits to every subsequent hands-on repair task.

Lesson 4 • Motorcycle Anatomy Overview

Identifies the primary systems: engine, drivetrain, chassis, electrical, and fuel. Provides the vocabulary needed to follow repair procedures accurately.

Lesson 1 • Oil Analysis and Lubrication Inspection

Identifies contamination, metal particles, and viscosity breakdown in engine oil. Early oil analysis prevents catastrophic engine failure during service intervals.

Lesson 2 • External Engine Inspection Procedures

Covers gasket leaks, case cracks, stud condition, and external seal assessment. Systematic external checks prevent missed faults before committing to full disassembly.

Lesson 3 • Engine Compression and Leak-Down Testing

Teaches compression gauge and leak-down tester procedures to quantify engine health. Results guide decisions on whether top-end or bottom-end work is required.

Lesson 4 • Four-Stroke Engine Operating Principles

Explains intake, compression, combustion, and exhaust strokes with timing relationships. This cycle is the reference point for all engine diagnosis and repair.

Lesson 1 • Cylinder Head Reassembly and Torque

Installs head gasket, torques head bolts in sequence, and sets valve clearances. Final torque and clearance settings directly determine engine reliability and longevity.

Lesson 2 • Piston and Ring Installation

Covers ring orientation, piston pin installation, and circlip retention procedures. Correct assembly prevents ring flutter, oil consumption, and piston seizure.

Lesson 3 • Valve Train Inspection and Reconditioning

Measures valve stem diameter, seat width, and spring free length against specifications. Proper valve seating restores compression and prevents combustion gas leakage.

Lesson 4 • Cylinder Head Removal and Disassembly

Covers cam chain tension relief, head bolt removal sequences, and component organization. Correct disassembly prevents warped mating surfaces and lost hardware.

Lesson 1 • Crankshaft Inspection and Measurement

Measures crankshaft runout, rod big-end play, and main journal diameter. These measurements determine whether the crankshaft can be reused or requires replacement.

Lesson 2 • Bearing Selection and Installation

Explains bearing codes, interference fit, and thermal installation techniques. Correct bearing fit prevents premature failure and excessive engine noise.

Lesson 3 • Transmission Gear Inspection

Inspects shift forks, gear dogs, and selector drum for wear and damage. Worn transmission components cause missed shifts and gear lockout under load.

Lesson 4 • Crankcase Splitting and Organization

Covers case splitting sequences, dowel pin removal, and systematic parts organization. Proper organization prevents assembly errors and lost components during rebuild.

Lesson 1 • Carburetor Disassembly and Cleaning

Covers ultrasonic cleaning, jet inspection, and passage verification procedures. Thorough cleaning restores fuel flow without damaging soft aluminum components.

Lesson 2 • Carburetor Synchronization on Multi-Cylinder Engines

Uses vacuum gauges to balance airflow across multiple carburetors at idle. Balanced carburetors eliminate vibration and uneven power delivery between cylinders.

Lesson 3 • Fuel Injection Diagnosis and Service

Uses scan tools and fuel pressure gauges to diagnose injector and sensor faults. Systematic testing reduces misdiagnosis and unnecessary component replacement.

Lesson 4 • Fuel Injection System Components

Identifies throttle body, fuel rail, injectors, MAP sensor, and ECU functions. Component knowledge enables accurate fault isolation before electrical testing begins.

Lesson 1 • Charging System Diagnosis and Repair

Tests stator output, rectifier-regulator function, and battery charge acceptance. A healthy charging system prevents stranded-rider failures and battery damage.

Lesson 2 • Starting System and Ignition Circuits

Diagnoses starter motor, solenoid, ignition switch, and kill switch circuit faults. Correct starting system function is critical for rider safety and engine protection.

Lesson 3 • Multimeter and Test Equipment Use

Teaches DC and AC voltage, resistance, continuity, and diode testing procedures. Accurate meter use is the primary skill for all electrical fault isolation.

Lesson 4 • Electrical Theory for Motorcycle Technicians

Covers voltage, current, resistance, and Ohm's Law as applied to motorcycle circuits. This foundation enables correct interpretation of all electrical test results.

Lesson 1 • Frame and Steering Head Inspection

Checks frame alignment, steering head bearing preload, and neck weld integrity. Frame faults compromise rider control and cannot be masked by other adjustments.

Lesson 2 • Brake Rotor and Pad Inspection

Measures rotor thickness, runout, and pad friction material depth against specifications. Worn rotors and pads increase stopping distance and risk brake fade.

Lesson 3 • Rear Suspension Inspection and Adjustment

Inspects linkage bearings, shock absorber function, and spring preload settings. Rear suspension condition directly affects traction, stability, and rider comfort.

Lesson 4 • Hydraulic Brake System Service

Covers master cylinder, caliper rebuild, brake line inspection, and fluid bleeding. Properly bled brakes with correct pad thickness ensure reliable stopping power.

Lesson 1 • Clutch System Inspection and Adjustment

Inspects friction plates, steel plates, and spring free length, then sets cable freeplay. Correct clutch adjustment prevents slipping under load and dragging at rest.

Lesson 2 • Belt and Shaft Drive Service

Covers belt tension, pulley wear, and shaft drive gear oil service procedures. Belt and shaft systems require different service intervals and failure modes than chain drives.

Lesson 3 • Pre-Delivery Inspection and Road Test

Executes a systematic pre-delivery checklist covering all systems before customer handoff. A documented road test confirms repairs under real operating conditions.

Lesson 4 • Chain and Sprocket Service

Measures chain stretch, sprocket wear, and performs adjustment and lubrication. Correct chain tension and lubrication prevent premature wear and power loss.
