Naraku CVT KIT (Aprilia, JOG, Zuma 50)
Description: Naraku CVT KIT aka Super CVT transmission kit for 40QMB 2-stroke engines. Complete transmission kit of Naraku components, all tuned to another. Since Chinese-built scooters are not kitted with top-end components out of the factory, this is the easiest way to overhaul the transmission without expert help. This negates any restrictions. Top speed and drivability on hills are improved, meaning higher top end and better acceleration! Kit contains variator, variator sleeves, belt, belt pulley, clutch, and clutch bell. Suitable for all 2-stroke scooters with 1E40QMB and 1PE40QMB engines with a 16mm crankshaft and a belt length of 788mm. Kit for scooters in untuned condition. Where changes are made to exhaust or cylinder, the variator must also be adapted and, where necessary, a stronger counter pressure spring fitted.
NOTE: Recommend using a new belt with this kit. Belt and the belt drive-facing plates KEEP DRY. All, other areas apply moly-graphite grease when assembling. Example, lubricate slider grooves, slider pins, ball bearing seat, and inner funnel area with heat-resistant moly-graphite grease.
Installation: 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.
