Scooter transmission tuning and cvt explained. Description of all the cvt components, what they do, how they work, and how to diagnose and tune. Cvt, is 90% of the tuning process in my opinion
Unlike a conventional automatic transmission system, the CVT does not make use of gears. Instead, it has two pulleys, whose diameters are variable and are connected by a belt or a chain. One end is connected to the engine and the other one is linked to the wheels, where the power is delivered. The pulleys are movable and as they come closer to each other, the belt or the chain rides higher making the diameters of the pulleys larger and vice-versa.
When the Input Pulley is becomes smaller and the output pulley becomes larger translates into a lower ratio (which is the number of times the shaft spins for every revolution of the engine, hence a ratio). While the scooter gathers momentum and accelerates, the pulleys keep varying their diameters and lower the engine speed (RPMs) for relaxed cruising or climbing up the revs for quick overtaking.
