NARAKU Cylinder Kit V.2 70cc (ref. NK100.31.2)

Designed for air-cooled horizontal Minarelli engines, this 70 cm³ Naraku cylinder kit prioritises torque and responsiveness at low revs. Ideal for urban riding and lightweight quads, it delivers sharp acceleration just above idle, making starts and pickups easier — even when loaded or with a passenger — without pushing the engine to excessive revs.

• Torque-oriented: optimised performance at low and mid-range revs.
• Engine behaviour suited for daily use; compatible with the original exhaust.
• Discreet sound: remains close to a standard character.
• Compatible with original and sports exhausts.
• Carburettor adjustment: increase the jet by approximately +7% to +10%.

For optimal tuning, using a head with an appropriate chamber (for example, a Naraku 70cc head) is recommended. However, the kit can operate with the original head, but be cautious: the compression will be increased and the electric starter may have difficulty turning the engine over.

Particularly suitable for scooters and quads equipped with horizontal Minarelli blocks (e.g. AEON Minikolt, Adly Blizzard, Yamaha Neos).
