Why Does a Motorcycle Burn Engine Oil in Summer?

[LeCarson]

Motorcycle burning engine oil is due to the piston ring oil ring having insufficient elasticity and excessive light leakage. Insufficient elasticity and excessive light leakage: When the piston ring oil ring has insufficient elasticity and excessive light leakage, it leads to burning engine oil, which is a problem with the piston ring itself. If the gap between the valve stem and the valve guide is too large, or the valve oil seal does not seal tightly, this burning oil phenomenon is unrelated to the piston ring. Even after replacing the piston ring, the engine oil may still burn. Cylinder size deviation and excessive ovality: If the cylinder size is out of tolerance and the ovality is excessive, or if the surface has scratches or grooves, the oil ring cannot scrape off the excess oil on the cylinder wall, causing oil to enter the combustion chamber and participate in combustion. If the taper ring is installed upside down, it will scrape oil upward, also increasing oil consumption. If the piston rings are not staggered in position during assembly and are aligned in a straight line, oil consumption will sharply increase.
