How to Rebuild Honda Motorcycle Carbs
- 1). Remove the throttle cables and fuel lines from the carburetor by loosening the fittings holding them in place -- this may require a wrench. Tag them as they are removed so as to be sure where each of them goes on reassembly.
- 2). Loosen the screws holding the carburetor to the air box with a Phillips screwdriver and remove the nuts holding the carburetor to the engine head with a wrench. You can now ease the carburetor out of the motorcycle frame.
- 3). Loosen the screws on the rear of the carburetor and remove the bowl, the curved rear section, which will reveal the inner workings of the carburetor.
- 4). Remove the float from the carburetor, the noticeably large rotating component which will take up most of the space inside the carburetor. This may require a hinge on the float to be removed, but this can be simply pulled out using your fingers.
- 1). Scrub away any dirt and residue from the entire inside of the carburetor, using a flathead screwdriver to remove tough stains. Use a commercial carburetor cleaner to help remove the residue, ensuring to spray it into all nooks and crannies and down all holes.
- 2). Remove the jets by unscrewing them; this may be done with a wrench or screwdriver depending on which tool fits the top of the jet. Place them in a bowl of carburetor cleaner overnight, using a toothbrush to finish of cleaning them.
- 3). Thread a small piece of wire through the jets to remove excess residue from within and wash it away with more of the carburetor cleaner.
- 4). Polish the exterior of the carburetor with fine steel wool and apply a coating of protective spray appropriate to the metal.
- 1). Insert the jets and float back into the carburetor and screw the bowl back in place.
- 2). Place the carburetor back on the motorcycle and tighten the screws and nuts which hold it in place.
- 3). Replace the fuel and throttle lines and ensure they are tight before starting the engine.
