Honda motorcycles use an in-line fuel filter on the majority of their bikes. Some older models use an in-tank filter that attaches directly to the fuel line through the tank selector switch. The fuel filters are relatively inexpensive. A damaged fuel filter needs to be replaced. Dirty fuel filters can be cleaned if replacement is not an option. Inspect your fuel filter at least once a year or after the bike has stood for a long period without being run. Cleaning the fuel filter is the same process regardless of the manufacturer of the bike.
Remove the fuel filter. Most fuel filters are clamped in place with pinch clamps. Use pliers to remove the clamps and pull the hoses off the filter. Some screw into the frame or bolt into the tank. Use screwdrivers or a wrench to remove the filter properly. Consult your specific model's owners manual for the exact process.
Spray carburettor cleaner into the opening of the filter. The flow of fuel goes in one direction -- towards the engine. Spray the cleaner in the opposite direction while holding the filter over a rag.
Bend a pipe cleaner in half and insert it lightly into the filter. Do not force the pipe cleaner into the filter or you may damage the filter. Spin the pipe cleaner around to brush off any stuck-on residue.
Submerge the filter in clean gasoline and allow it to sit for about an hour.
Remove the filter and wipe it clean with a clean rag. Reinstall the fuel filter onto the bike.
