My motorcycle engine is 125. Can you change it into 200?

When the intake valve of motorcycle engine is closed, the inertia airflow of carburetor impacts the valve and the conduit, and impacts the carburetor throttle valve in the opposite direction, resulting in back injection. When the intake valve is closed, using the negative pressure principle, the reverse jet airflow generated by the sudden disconnection will be expanded.

Motorcycle engines work on the same principle as car engines. The engine consists of a piston, a cylinder block and a cylinder head, and the cylinder head contains a valve mechanism. When the spark ignites the mixture of fuel and air, it will cause an explosion and push the piston to move up and down in the cylinder block.

Then the valve is opened and closed, so that the mixture of fuel and air enters the combustion chamber. The up-and-down motion of the piston drives the crankshaft to rotate, and the energy of the piston is converted into rotary motion. The rotating force of the crankshaft is transmitted to the rear wheel of the motorcycle through the transmission.

Extended data:

Motorcycle power plants are all internal combustion engines; Engines that use diesel as fuel are customarily called diesel engines, while engines that use gasoline as fuel are called gasoline engines. Because gasoline engines have the advantages of light weight, small volume, low noise and vibration, easy starting and low cost, gasoline engines are widely used as power devices for motorcycles.

Every time the engine crankshaft rotates, that is, the piston reciprocates up and down for two strokes to complete a working cycle. Four-stroke engine: an engine that completes a working cycle every time the crankshaft rotates, that is, the piston reciprocates up and down for four strokes. Working cycle refers to the working process of the engine, which consists of intake, compression, combustion expansion (doing work) and exhaust stroke. The process that the engine completes intake, compression, work and exhaust at one time is called a working cycle, also known as cycle.
