Stage6 Drive Face 16mm CNC-Machined (40QMB, Minarelli)

Description: Stage6 Drive Face 16mm CNC-Machined for 40QMB, Minarelli 2-stroke engine. Drive face with optimized drive face angle. In order to keep costs down, original racing drives are usually cast or - even worse - pressed steel. When these parts are cooling down after casting, the metal is still molten and the drive face angles can often vary. Due to the fact that racing engines have a very narrow power band, these tolerances have direct consequences on the power output. In contrast to those standard versions, the Stage6 racing drive is precisely CNC cut out of solid material. All in all, more than twelve different versions were tested to find the optimal angle. The high-quality alloys and the special surface coating used in this drive face make cooling fins unnecessary. The reduced mass has of course positive results for the power at the rear wheel. This racing drive was actually developed for drag races, but Freddy Koopmans also used them with his racing scooters in the 2004 season.

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.
