Carburetor Adjustment, Stopping, and Braking System

Carburetor Adjustment Guidelines

Carburetor is factory adjusted but may need tuning based on climate/altitude. Ensure the motorcycle does not move while idling.

Stopping the Motorcycle

In emergencies, stop using the throttle or switch. Normally, reduce engine speed for 3-5 minutes, then use the stop switch.

Braking System Description

Uses a disc/caliper system activated by handlebar levers. Use the left hand for the rear brake. Release throttle when braking.

Brake and Chain Adjustment

Adjusting the Brakes

Brakes should be pre-adjusted but may need occasional tuning. Adjust tension screw on the brake line to tighten or loosen.

Squeaky Brakes Explanation

Brakes may squeak during the break-in period, which is normal and does not affect performance.

Adjusting the Chains

Chains need proper alignment with sprockets to prevent wear. Check for skipping (too loose) or humming (too tight).

Chain Adjustment and Maintenance Schedule

Proper Chain Tensioning

Achieve correct tension by adjusting the chain from loose to lightly tense. Loosen axle bolts, adjust chain, rotate wheel, then tighten bolts.

Daily Maintenance Tasks

Perform each ride: Check for fuel/air leaks and ensure nuts/bolts are tight.

Weekly/Monthly Maintenance

Check pull starter cord, spark plug gap (adjust to 0.6mm), cylinder cooling fins, and air intake. Clean air filter.

Storage and Troubleshooting

Long-Term Storage Procedures

Remove fuel, close choke, draw starter. Add oil to cylinder via spark plug hole, rotate starter. Clean engine and frame with oiled cloth.

Troubleshooting: Engine Start Issues

If the engine fails to start, check for water in gasoline, carbon buildup on spark plug, or poor high-voltage wire connection.

Troubleshooting: Slow Engine Speed

If engine starts but runs slowly, check choke position, engine oil/gasoline ratio, and for water in the gasoline.

Troubleshooting Engine Performance

Troubleshooting: Low Engine Power

Low power may be due to a blocked air filter, clogged exhaust/muffler, worn piston/rings, blocked fuel strainer, or air/oil leaks.

Troubleshooting: Sudden Engine Stoppage

Sudden stops can be caused by running out of fuel, loose high-voltage wires, fouled spark plugs, blocked fuel strainers, water in fuel, or blocked tank lid air hole.

Troubleshooting: Engine Not Stopping

If the engine cannot be stopped, check for an open circuit in the stopping wire of the switch.
