What Could Be the Reasons for a Motorcycle That Can Start but Not Move?
1 Answers
Motorcycle can start but not move may be due to damaged automatic centrifugal clutch, broken transmission belt, insufficient piston thrust, carburetor water ingress or blockage, or burnt spark plug. Damaged automatic centrifugal clutch: Improper clutch operation or failure to return to position causing the motorcycle to start but not accelerate or move. A faulty automatic centrifugal clutch needs replacement or repair. Broken transmission belt: Generally caused by a faulty pulley or belt, which requires opening the rear transmission system for inspection. If the belt is broken or has significant gaps, a new belt must be replaced. Insufficient piston thrust: Lean fuel mixture causing insufficient gas thrust on the piston after ignition, leading to prolonged combustion time and engine overheating. Carburetor water ingress or blockage, burnt spark plug: Check if the fuel line is blocked. Loosen the bottom screw of the carburetor to let the gasoline flow for a while before tightening it. If dirt has entered the carburetor, check the spark plug. The carburetor needs cleaning or replacement after prolonged use, and a burnt spark plug must be replaced promptly.
