[QUOTE="Chokey, post: 1018807, member: 47391"] The purpose of the powerjet (in thoery) is to ensure a rich enough mixture under a load when the engine is at it's torque peak to make good power without detonation, while being able to have a lean enough mixture at high rpms to have a decent amount of overrev, hence the reason the powerjet shuts off at around 9000 rpm. In real-world use, I've tried my KX with it both connected and disconnected, and found the difference to be subtle but noticeable. If you disconnect the solenoid, the powerjet doesn't close at high rpms, so you lose a little bit of overrev at the very top. It won't affect the midrange pull or peak hp. If you don't scream your engine, you'll never notice a difference with it disconnected. [/QUOTE]
