The Dell'orto FN266 needle strend is a key piece of the engine carburation system Rotax Max. Internal element of the DELL'ORTO VHSB carburettor, it plays a decisive role in the accuracy of the air / gasoline mixture and directly influences the engine response, idling stability, as well as mid-speed performance and at full load.

Designed according to official specifications RotaxThe PUT FN266 guarantees optimal control of the gas flow when the bushel needle moves in its duct. Its machining of very high precision ensures a constant diet, without irregularities, even in the most demanding race conditions: high temperatures, altitude variations, evolution of the gum on the track or rapid changes in turn.

The FN266 is the approved and recommended needle stream for engines Rotax Max senior, Rotax Max Junior, Rotax Max EVO, and some mini / max configurations depending on the factory settings. Its specific design makes it possible to obtain a perfect balance between wealth and responsiveness, promoting clean combustion, a linear torque and a more flexible motor in all acceleration phases.

Durable and reliable, it resists wear caused by flow variations and the friction of the needle, ensuring a constancy of performance over time. It is a key element to maintain optimal motor behavior, avoid acceleration holes and get accurate settings during focus sessions (main spray, needle, diffuser ...).
