What Causes Motorcycle Smoke?
1 Answers
Motorcycle smoke is mainly caused by issues such as poor sealing of the valve oil seal, excessive clearance between the piston rings and cylinder, or damage to the cylinder gasket, which require timely repair. Below are the consequences of valve oil seal leakage: Consequence 1: Engine oil that seeps into the combustion chamber due to poor sealing of the valve oil seal will burn in the combustion chamber, typically resulting in blue smoke from the exhaust. If this persists for too long, carbon deposits can easily form on the valves, leading to poor valve sealing and incomplete combustion. Consequence 2: It can cause carbon buildup in the combustion chamber and fuel injectors or clog the catalytic converter. Additionally, it may result in reduced engine power, significantly increased fuel consumption, damage to related components, and notably worsened spark plug performance.
