Why Can't a Motorcycle Start in Gear?

[Marc]

Motorcycle cannot start in gear due to the following reasons: Excessively small valve clearance: Too small valve clearance leads to an abnormal fuel-air mixture ratio when the engine is cold, making it difficult to start. Solution: Adjust the valve clearance. Poor spark plug performance: As a wearable part, spark plugs require regular replacement. Insufficient energy makes ignition difficult. Solution: Check for carbon deposits or corrosion on the spark plug and replace it if necessary. Malfunctioning electronic choke in the carburetor: A faulty electronic choke can still cause an improper mixture ratio. Solution: Adjust the choke or replace the control component.
