What causes a motorcycle engine to overheat severely and lose power?

[BrielleFitz]

The reasons and solutions for a motorcycle engine overheating severely and losing power are as follows: Excessive oil: Too much engine oil affects the engine's heat dissipation and increases its operating resistance. You can fix this by draining the excess oil according to the oil level marks on the dipstick. Ignition timing: Incorrect engine ignition timing, which includes two aspects: one is caused by faulty electrical components such as the ignition coil, spark plug, or high-voltage pack, and replacing the faulty parts can fix the issue. The other aspect is caused by misalignment of the engine timing gears, leading to ignition timing disorder, often occurring after engine repairs, and realigning the timing gears can fix the problem. Exhaust port blockage: A blocked cylinder head exhaust port causes poor engine exhaust, significant power loss, and excessive heat generation. Appropriate measures should be taken to clear the blockage, and in severe cases, replacing the faulty part is recommended.
