: Users can assign fixed relationships between different ports. For instance, entering the exhaust timing can automatically calculate all transfer port heights based on user-defined offsets. Visual Interface
: Inputs and outputs use color-coding (e.g., green for valid calculations, red for outputs) to help tuners quickly identify required modifications. Modification Logic Porting Calculator V4.2.2
In the world of two-stroke tuning, "pretty" ports do not always equal power. As noted by experts on community platforms like Facebook , many tuners focus on polishing areas that don't affect performance. : Users can assign fixed relationships between different
It calculates port heights from durations or durations from port heights. For example, a user can enter a target open duration in degrees to determine the exact millimeter measurement required for grinding the cylinder. Modification Logic In the world of two-stroke tuning,
: By entering just the exhaust timing, the software can automatically calculate all transfer port heights based on fixed relationships.
