Complete tuning set from the manufacturer Naraku for scooters equipped with Minarelli horizontal air-cooled two-stroke (2T / AC) engines.
Naraku RevUp aluminum cylinder for everyday use with high torque. With a bore of 47 mm, huge intake ports, and a nickel-carbide-silicon coated casing, the cylinder has significantly better heat dissipation and great propulsion due to its aluminum construction. The crankshaft increases pre-compression in the crankcase, leading to a significantly better filling ratio. Performance speed shifts to the upper range. The heavier flywheel mass of the full metal version not only increases performance but also torque. The Naraku V.2 intake system includes 2 adapters for all common tuning carburetors. The carburetor, which is comparable to PHBG types, has a bore of 21 mm and fits perfectly with this Naraku RevUp kit.
