What Causes a Motorcycle to Stall When the Choke is Opened?
1 Answers
Motorcycle stalling when the choke is opened is due to an excessively lean air-fuel mixture, which primarily stems from two reasons. Improper mixture adjustment: In this case, readjustment is necessary. Generally, you can slightly turn the adjustment screw inward by about one full turn to reduce the carburetor's air intake, thereby enriching the air-fuel mixture. Low fuel level: A low fuel level also requires readjustment. However, if the carburetor is excessively worn out, it may need replacement. Typically, you can thoroughly clean the carburetor once and slightly raise the fuel level for a test run. If the issue resolves, replacing the carburetor may not be necessary.
