Naraku Compression Spring 1000 RPM (DIO, GET, QMB)
Description: Naraku Compression Spring aka torque spring do a couple of things. First, they supply the pressure to engage the belt. They also determine the rate at which the CVT transmission changes from low to high gear. A 1000rpm spring will go into a higher gear than a 2000rpm spring. Markings on the spring help you identify the strength of the spring, for example, a spring marked 1000 RPM will delay the reaction by 1000 RPM. The greater RPM spring will provide you with the greater power. Naraku counter pressure spring 1000 RPM uses a modified alloy spring providing better resilience and above average strength for 139QMB, Buddy50, RoughHouse, and many another GY6 50cc base engine.
