Fuel-Air Mixture Formation: The carburetor regulates the ratio of air to gasoline through nozzles and throttle valves (throttle). During engine operation, air enters the carburetor, where it mixes with gasoline drawn from the fuel system to form a combustible mixture. Mixture Adjustment: The carburetor adjusts the richness of the mixture based on the engine's current operating conditions (such as RPM, load, temperature). For instance, higher RPMs require a richer mixture to

The motorcycle crankshaft is a crucial component of the engine, playing a key role in converting reciprocating motion of the piston into rotational motion. Its main functions include: Converting Motion: The crankshaft transforms the up-and-down reciprocating motion of the piston into continuous rotational motion. As the piston moves up and down inside the cylinder, the crankshaft, through connecting rods, converts this linear motion into rotational motion, thereby driving the
