Since 1989, Japanese motorcycle manufacturer Suzuki has produced the Bandit series of standard street bikes. Introduced to consumers for the 1991 model year, these motorcycles have become a catalyst in promoting motorcycles in the United States for Suzuki. Available in a variety of engine sizes and package options, all Bandit edition motorcycles feature four-cylinder engines. These motors featured dual overhead camshafts per cylinder (DOHC) and 16 valves. Until 1997, the engines relied on a carburettor for fuel and air mixture, while following models were upgraded to fuel-injection. Keeping these engines tuned properly can be done at home with the right tools and know-how.

    Oil and Oil Filter

  1. 1

    Start the engine of your Suzuki Bandit motorcycle and let it run for about 10 minutes. Warm engine oil will flow more quickly while draining.

  2. 2

    Place an oil recycling container underneath the oil pan of the motorcycle's engine. Remove the oil filler cap to allow draining to occur more consistently. Use a wrench to remove the oil drain plug, located on the side of the oil pan. Wipe the area around the plug with a cloth once draining has finished. Screw the drain plug back into place.

  3. 3

    Move the oil recycling container underneath the old oil filter. Use the necessary wrench to remove this filter and filter cover, using caution as to not cause oil to spill everywhere. Pull this oil filter from its housing unit and discard. Replace the O-ring with the one provided with your new oil filter. Attach the new oil filter to the housing unit and hand-screw into place until secure.

  4. 4

    Use the oil funnel to guide new oil into the engine's oil compartment. Add 1.5 quarts of new motor oil to the engine. A variety of different oils are available for your specific bike and how you ride it. Replace the oil filler cap once you are finished.

  5. 5

    Start the engine of your motorcycle and let it run for five minutes. Check the oil level in your engine by removing the dipstick. Turn off the engine and add more engine oil to the compartment, if necessary.

    Air Filter

  1. 1

    Locate the air filter, responsible for monitoring air flow into the engine's carburettor or fuel-injectors. On many models, this filter is located underneath the seat. Some models feature an air filter casing unit, housed on the side of the motorcycle panel. Remove any panels or seats to access this filter.

  2. 2

    Remove the old air filter from the filter system by hand. Remove slowly as to not spill any dirt or other debris that might have fallen into this area.

  3. 3

    Clean the area inside the filter box and its neighbouring parts thoroughly. The slightest amount of debris can prohibit the engine from receiving the necessary amount of air it needs to perform.

  4. 4

    Install the new filter directly as the old one was removed. With aftermarket, performance-type filters, the shape is meant to bolt directly into the factory position. The wire-mesh design of these filters allow for reuse year after year, while increasing performance.

  5. 5

    Replace the panels or seat once you are finished replacing the air filter. Start the engine of your Bandit and make sure everything is running properly.

Tips and warnings

  • Wear gloves at all times to reduce friction on your hands when removing parts.
