An engine modification, frequently employed in small displacement engines, increases the cylinder’s internal diameter. This enlargement allows for a greater volume within the cylinder, subsequently permitting a larger air-fuel mixture to enter. The result is a heightened combustion process during each engine cycle, ultimately leading to amplified power output. One common example targets engines originally designed with a smaller displacement, transforming them to a larger capacity.
The utilization of this modification offers several advantages. The most significant is the potential for increased horsepower and torque, providing enhanced acceleration and overall performance. Historically, this type of upgrade has been favored in recreational vehicles such as pit bikes and mini-ATVs where maximizing performance from a compact engine is desired. The change can revitalize an older machine, providing an economical alternative to purchasing a newer, more powerful model.
