A continuously variable transmission driven pulley movable sheave comprising a beveled face disk, an elongated hollow cylindrical collar extending orthogonally from a center of the beveled face disk, and a triangular shaped tuning pocket disposed in the collar. The tuning pocket is structured and operable to control axial movement of the movable sheave on the elongated neck of the driven pulley. The tuning pocket comprises a first gear side, an acceleration side disposed at a positive angle relative to a reference point on the first gear side, and a deceleration side disposed at a negative angle relative to the reference point on the first gear side.

Continuously variable transmission having tunable acceleration and deceleration

A method for cold engine starting in a pedal-start vehicle that comprises determining an ICE temperature value of an internal combustion engine of the vehicle upon starting the engine via depression of an accelerator, then comparing the ICE temperature value to a predetermined ICE temperature threshold value. Thereafter, when the ICE temperature value is below a predetermined ICE threshold value, controlling operation of the engine such that an RPM of the internal combustion engine remains within a predetermined idle RPM range for a predetermined amount of time, regardless of throttle control commands from the accelerator pedal of the vehicle, or when the ICE temperature value is equal to or greater than the predetermined ICE threshold value, or controlling operation of the internal combustion engine in accordance with the throttle control commands from the accelerator pedal.
