To clean the pilot jet on a 1965 Honda CB160, you can follow these steps:
Prepare the Necessary Tools: Gather the tools you will need, including a screwdriver, carburetor cleaner, compressed air, and a small wire or needle.
Access the Carburetor: Remove the carburetor from the motorcycle. This typically involves disconnecting the fuel line and loosening the clamps that hold the carburetor in place.
Locate the Pilot Jet: Once the carburetor is removed, locate the pilot jet. It is a small brass screw located on the bottom of the carburetor.
Remove the Pilot Jet: Use a screwdriver to carefully unscrew the pilot jet from the carburetor body. Take note of the orientation and how many turns it takes to remove it.
Clean the Pilot Jet: Inspect the pilot jet for any clogs or debris. Use a carburetor cleaner to spray through the jet, ensuring it is fully cleaned. If the blockage is stubborn, you can use a small wire or needle to carefully clear the passage.
Clean the Carburetor Passages: While the pilot jet is removed, use the carburetor cleaner and compressed air to clean the surrounding passages and jets. Spray cleaner into the passages and use the compressed air to blow out any debris.
Reinstall the Pilot Jet: Once the pilot jet and carburetor passages are clean, reinstall the pilot jet back into the carburetor. Screw it in until it is snug but be careful not to overtighten.
Reinstall the Carburetor: Put the carburetor back onto the motorcycle, reconnecting the fuel line and securing the clamps.
Test and Adjust: Start the motorcycle and let it run for a few minutes to ensure smooth operation. If necessary, you may need to adjust the pilot screw (if your carburetor has one) to fine-tune the air-fuel mixture.
It's important to note that these steps are general guidelines, and the specific procedure may vary depending on your Honda CB160 model and carburetor design. Always consult the service manual or seek professional assistance if you are unsure or need specific instructions for your motorcycle.
