The purpose of this system according to the motorcycle manufacturers’ marketing departments is to create back-pressure at lower RPM’s to increase torque. Unfortunately, this probably isn’t the real reason; the true purpose of the exup valves is to meet noise and emissions regulations. The exhaust valves are partially closed at idle and low rpm to reduce noise, and closed again at the upper RPMs to meet peak noise and emissions regulations. The proof of this has been shown on the dyno where removing the valves and retuning the engine creates a flatter better torque curve.

Спасибо за инфу. Звонил в Фабрику Железных игрушек договорился о встрече. Сказали, возможно тросик не просто так срезали... надо подключаться к мозгам а дальше смотреть. Либо ставить тросик либо обманку
