The mini bike Comet 500 series torque converter is one of the top clutches from the Comet series especially designed for small engines. Check the range at OMB Warehouse. How does the mini bike Comet 500 series work? The drive clutch is activated by centrifugal force from the engine crankshaft. The movable sheave of the clutch is forced in as the RPM of the engine is increased. This contacts the drive belt. The drive belt will then be forced to a larger diameter within the clutch sheaves, thus pulling it to a smaller diameter within the driven unit sheaves. The movable sheave of the driven unit is forced out, allowing the belt to seek its smaller, high speed ratio diameter. The mini bike Comet 500 series drive and driven variable pulleys are installed in a power train drive system to better match output requirements with an engine output. If the engine is allowed to run at its peak output power, the most power available from the engine will be directed to the driven shaft. The model 500 responds to load requirements and changes the ratio between the drive and driven pulleys so that the engine can maintain its peak power output.
