Riding a classic Honda CB motorcycle offers a one-of-a-kind experience that blends timeless style with legendary performance. Whether you're revving up a CB750, CB550, or another model in the CB family, regular maintenance is essential for preserving the reliability and enjoyment these bikes are known for. Keeping your motorcycle in top shape ensures it continues to perform just as impressively as when it first rolled off the assembly line.

At VintageCB750, we understand the importance of proper care for your vintage bike, and we’re here to provide you with some essential tips to help you maintain your CB motorcycle.


1. Regular Oil Changes

Oil is the lifeblood of your motorcycle's engine. Regularly changing the oil is one of the most important aspects of keeping your CB motorcycle in top shape. Fresh oil ensures that the engine parts are properly lubricated, reducing friction and wear.

  • How often to change the oil: For classic CB motorcycles, it's recommended to change the oil every 2,000 to 3,000 miles or at least once a year. If you're using your motorcycle for long-distance rides or in harsher conditions, you might want to change it more often.
  • Pro tip: Always use high-quality motorcycle-specific oil for best performance and longevity.


2. Keep the Air Filter Clean

A clean air filter ensures that your engine is getting the right amount of air for optimal performance. Clogged or dirty air filters can reduce engine efficiency and fuel economy, causing your bike to run rough.

  • How often to check: Inspect your air filter every 1,000 to 1,500 miles, or more often if you ride in dusty or harsh conditions. Clean or replace the air filter if it appears dirty or clogged.
  • Pro tip: Foam air filters are often a great upgrade for classic bikes like the CB series, as they are more durable and can be cleaned and reused multiple times.

3. Chain Maintenance

Your CB motorcycle’s chain is vital for transferring power from the engine to the rear wheel. Keeping the chain in proper condition ensures smooth and efficient operation.

  • How to maintain: Regularly check the chain for tension, lubrication, and wear. The chain should be adjusted to ensure it has the right amount of slack—about 1 to 1.5 inches of play.
  • Lubrication: Use a good quality motorcycle chain lube to ensure smooth operation and reduce wear.
  • Pro tip: If the chain is worn or damaged, replace it promptly to avoid additional damage to other parts of your motorcycle.

4. Inspect and Maintain the Brakes

Your brakes are the most important safety feature on your CB motorcycle. Regular brake inspections ensure that you're stopping as efficiently and safely as possible.

  • How often to check: Inspect your brake pads every 1,500 miles. If they appear worn or thin, replace them. 
  • Brake lines and cables: Inspect the brake lines for any signs of wear, cracking, or leaks. For cable-operated brakes, make sure the cables are adjusted properly and lubricated.
  • Pro tip: If your CB motorcycle uses drum brakes, make sure to check for wear and adjust the brake shoes accordingly for optimal braking performance.


5. Carburetor Care

The carburetors on your CB motorcycle play a crucial role in mixing air and fuel for combustion. Over time, carburetors can become clogged with dirt, varnish from old fuel, or other debris. This can cause poor engine performance, including difficulty starting or rough running.

  • How to maintain: Clean the carburetors regularly, especially if your motorcycle has been sitting unused for a while. Disassemble them and clean with carb cleaner to remove any deposits.
  • Fuel treatment: If you’re storing your CB motorcycle for the winter or an extended period, treat the fuel with a stabilizer to prevent it from gumming up the carbs.

6. Battery Maintenance

A well-maintained battery is crucial for reliable starts and powering your electrical systems. Make sure to regularly inspect the battery and keep it in top condition.

  • How to maintain: Clean the battery terminals regularly and make sure they're free of corrosion. If the battery is a traditional lead-acid battery, check the fluid levels and top them off with distilled water as needed.
  • Pro tip: If your CB motorcycle has been sitting idle for a while, you may want to use a battery tender to keep the battery in good shape and prevent it from discharging.

7. Check Tire Pressure and Condition

Tires are the only point of contact your CB motorcycle has with the road, so it's essential to ensure they're in good condition.

  • How often to check: Check tire pressure every 1,000 miles or at least once a month. Under-inflated tires can cause poor handling, reduced fuel economy, and excessive wear. Always check tire pressure when the tires are cold for the most accurate reading.
  • Tire condition: Look for signs of wear, such as cracks, bald spots, or punctures. Replace tires when the tread is worn down or the rubber shows signs of aging.
  • Pro tip: Always use the recommended tire pressure listed in your owner's manual for the best performance and handling.


8. Regularly Clean and Protect Your Motorcycle

A clean bike not only looks better but can also last longer. Regular cleaning and maintenance of the frame, engine, and components help prevent rust and deterioration.

  • How to clean: Use a gentle cleaner and soft cloth to wipe down your CB motorcycle. Avoid harsh chemicals that could damage the paint or chrome. Always dry your bike thoroughly to prevent water from sitting and causing rust.
  • Protecting your bike: Apply a coat of wax to the painted surfaces and a chrome polish to keep your bike looking shiny and new.
  • Pro tip: If you ride in wet conditions, take extra care to clean and dry the bike to prevent corrosion.

9. Storage Tips for Winter or Long-Term Storage

If you’re storing your CB motorcycle for the winter or for an extended period, taking the proper steps ensures it’s ready to ride when you are.

  • How to store: Store your bike in a dry place, Use a motorcycle cover to protect it from dust and dirt. If you’re storing it for a long time, it’s a good idea to drain the fuel tank or use a fuel stabilizer.
  • Battery care: If you’re not using your bike for an extended period, consider removing the battery and storing it in a cool, dry place. This will help prolong its lifespan.
