General Tips for Rebuilding a Motorcycle Carburetor
This article provides general tips for rebuilding a motorcycle carburetor. The advantage of rebuilding it by yourself includes cost saving, time saving, and new skill learning. You can rebuilt the carburetor within four hours, it's cheaper than replacing it with a new one and it helps you learn a new skill even if it is a detailed task.
Preparing and Removing the Carburetor
Remove the motorcycle carburetor from the engine by disconnecting the lines attached to it and the bolts and nuts also secured to it. Leave a mark on the removed lines as a guide when reinstalled. Prepare your workbench where you will place the carburetor facing up. Make sure it is clean and well-lit. Open the fasteners, secured with screws, which hold the carburetor cover to the body using either a screwdriver or a wrench.
Clean the Carb Cover
Observe the accelerator’s pump and float inside the carburetor. Eliminate the gasket located at the top and bottom plates. Thoroughly clean the carburetor and soak the cover on a cleaning basin to completely get rid of the dirt. Apply a carburetor aerosol spray cleaner on the cover. Also include cleaning the corners and edges using a stiff brush or a paint brush to sweep the dirt residues. Set the cover aside and leave it to dry.
Apply oil or lubricant on a rag to clean the linkages. It will also lubricate the connector and joints of the carburetor. You may also use a compressed air spray for the cover to make sure that the unwanted fluids are eliminated.
Pull Out the Check Valves
Remove the check valves located beneath the carburetor base with the aide of a magnet.
Inspect the Jets
Make an inspection on the jets using a screwdriver. Damaged jets can cause problems and affect the performance of your bike. Make sure that the jets are clean and scratch free to allow regular flow of fuel. If the result of your inspection is bad, install new jets for best results. Install the new jets to their proper threaded ports.
Thoroughly Cleaning on the Base
Place the base to a cleaning container. Use either a spray to do the trick or soak it on a cleaning solution. Use a stiff brush to clean the edges, corners, and the insides. Make sure you clean the path where the fuel flows because this is where residue accumulates overtime. Use a compressed air spray to finalize the cleaning.
Reinstall the Components
Oil both the accelerator pump and the replaced new gasket. Slide the cover over the base and reinstall the gasket to its proper position. Secure the motorcycle carburetor with screws or nuts and bolts. Reinstall the linkages such as the choke and throttle to the carburetor.
Lastly, make an initial testing on the parts before completely rebuilding the carburetor. Place the carburetor back to the engine and connect the fuel lines and other cables. Press the accelerator to test if every component were properly attached. If the engines starts then you are done rebuilding the carburetor.
