  4. Every 4,800 miles: Replace spark plug, check brake pads.
  5. Every 7,200 miles: Change fork oil, check wheel bearings.

WARNING! Always use genuine Honda parts and recommended lubricants. Follow torque specifications precisely.

Engine Service

Complete engine disassembly, inspection, and reassembly procedures.

  1. Cylinder head removal: Remove camshaft, check valve clearance.
  2. Cylinder and piston: Measure cylinder wear, piston clearance.
  3. Crankshaft and connecting rod: Check big end play, rod alignment.
  4. Camshaft and timing: Set cam chain tension, check timing marks.
  5. RFVC system: Service radial four-valve combustion chamber.

CAUTION! Engine components are precision machined; handle with care to avoid damage.

Chassis & Suspension

Electrical System

Complete electrical system diagnosis and repair procedures.

Battery: 12V 10Ah, charging system output: 0.2kW at 5,000 rpm.

Ignition: CDI system testing, pulse generator inspection, ignition coil resistance checks. Lighting: Headlight (60/55W), brake/tail light (21/5W), turn signals (21W). Starting: Primary kickstarter mechanism, neutral safety switch. Charging: Three-phase AC generator, rectifier/regulator testing.

Fuel System

Dual carburetor service and fuel delivery system.

  1. Carburetor removal: Disconnect fuel lines, throttle cables.
  2. Carburetor disassembly: Clean jets, check float level.
  3. Synchronization: Balance dual carburetors using vacuum gauges.
  4. Fuel tank: Remove and clean, check petcock operation.
  5. Air filter: Clean foam element, re-oil properly.

Tip: Always use fresh fuel and stabilize if storing motorcycle.

Transmission & Clutch

5-speed transmission service and clutch system maintenance.

  1. Clutch inspection: Check plate thickness, spring free length.
  2. Transmission disassembly: Remove shift drum, forks, gears.
  3. Gear inspection: Check for wear, pitting, proper engagement.
  4. Shift mechanism: Inspect shift drum stopper, return spring.
  5. Chain drive: Adjust #520 chain to 1.2-1.6 inches play.
  6. Sprockets: Check for hooking, replace as set with chain.

WARNING! Transmission components must be properly aligned during reassembly.

Brake System

Front brake: Single piston caliper, 256mm disc. Rear brake: Single piston caliper, 220mm disc. Brake fluid: DOT 4, change every 2 years. Pad replacement: Minimum thickness 1.5mm. Brake line inspection: Check for cracks, leaks, deterioration.

Troubleshooting

SymptomPossible CauseCorrective Action
Hard startingValve clearance, carburetionAdjust valves to 0.005in (IN), 0.006in (EX); clean carburetors.
Poor performanceClogged jets, ignition timingClean carburetor jets; check CDI timing advance.
Transmission jumping out of gearWorn dogs, shift forkInspect gear engagement dogs; replace worn components.
Excessive oil consumptionWorn rings, valve guidesMeasure cylinder; replace rings; check valve stem seals.
Electrical failureStator, regulatorTest stator output (0.2kW); check regulator rectification.

Reset: Clear trouble codes by disconnecting battery if applicable.
