Can a Motorcycle with a Blown Engine Be Repaired?
2 Answers
Motorcycle with a blown engine can be repaired. Generally, in high-end vehicles, the computer will adjust the fuel injection timing when detonation occurs. If the situation is severe, it is necessary to go to a 4S shop to replace the piston and cylinder wall. In serious cases, the bearing shells also need to be replaced. If there are cracks, they must be replaced; otherwise, while driving, it could lead to cylinder scoring or complete piston shattering. Engine Blowout: Due to excessively high temperatures, the piston expands and gets stuck in the cylinder, causing the engine to be scrapped. In severe cases, when the pressure is too high and the piston cannot move, thick flames may shoot out. Conditions Leading to Engine Blowout: The main cause of an engine blowout is still the quality of the car, which is a design defect that causes the engine temperature to exceed the maximum temperature the engine can withstand, resulting in an engine blowout.
I've encountered motorcycle engine seizures several times, to be honest, whether it's repairable depends on the specific situation. If it's just a stuck piston or minor cylinder liner scoring, disassembling the engine and replacing the cylinder kit usually solves the problem - parts plus labor cost around 1,000 RMB. But if the connecting rod punches through the cylinder block or the crankshaft gets deformed, the repair cost could be half the price of a new engine. Last week I repaired a Honda CB400 - the owner kept riding with a failed oil pump until the piston rings fused to the cylinder walls and gouged deep grooves. Ended up having to replace the entire middle cylinder assembly for 2,600 RMB. The real headache is you still need to go through a 2,000 km break-in period after repairs. To prevent seizures, regularly check oil levels, don't wait until the air filter is completely clogged to replace it, and avoid constant redline gear shifts.
