Naraku Compression Spring 2000 RPM (DIO, GET, QMB)
Description: Naraku Compression Spring aka torque spring does 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 2000 RPM will delay the reaction by 2000 RPM. The greater RPM spring will provide you with greater power. Naraku counter pressure spring 2000 RPM uses a modified alloy spring providing better resilience and above-average strength for 139QMB, Buddy50, RoughHouse, and many other GY6 50cc base engines.

Installation: Make sure variator drive face is seated properly and not get its teeth chewed by the Bendix: 1. Slack the belt by opening the CVT clutch gives belt slack to the variator side. 2. Then install the variator drive face while lifting the slack belt further away from the center boss if done properly should not see any splines between variator drive face slop-side and boss flat-side. Should be flushed together. 3. Then install the existing variator fan, washer, and hand-tight nut. 4. Finally, apply blue Loctite, torque nut to 30-35ft-lbs. For reassurance please consult your manufacturer's variator torque specs.
