The Naraku HS-Racing is a well-engineered High Speed variator for Minarelli-based 2-stroke engines with a 16mm tail shaft. The variator comes with a CNC-turned HS belt pulley. The toothing allows for better transfer of power and negates the need for the star carrier shim. Very good torque and acceleration. The V.2 version comes with 3 sets of 15x12 weights in 5g, 5.5g and 6g.
The variator sleeve in the kit should be used with a sports exhaust or 70cc cylinder. The short build gives the variator a longer gear ratio, meaning more top end speed. Of course, you need sufficient power for this. For original 50cc engines, the original sleeve can be retained.
