What Causes a Motorcycle to Emit Blue Smoke?
1 Answers
Motorcycle emits blue smoke due to the following reasons: 1. Poor cylinder sealing leading to oil leakage into the cylinder, causing incomplete combustion; 2. Damaged valve guide or seal ring; 3. Excessive oil filling, resulting in more oil splashing onto the cylinder wall; 4. Aging valve oil seal with rubber losing elasticity; 5. Worn cylinder liner or insufficient piston ring tension and misaligned piston rings. The solutions for motorcycle emitting blue smoke are: 1. Replace the cylinder block, piston, piston rings, and cylinder gasket; 2. Check if the valve oil seal is not tightly sealed, and replace it promptly if there is an issue; 3. Use high-quality lubricating oil.
