Crankcase Internal Pressure Control Valve (for MV AGUSTA　F3/B3)

During traveling, the inside of the crankcase is pressurized by the high-speed reciprocating motion of the piston. This excessive pressure becomes a large resistance of the piston movement, causing various harmful effects. The internal pressure control valve keeps the crankcase internal pressure proper by merely installing, and it has great merit such as reduction of vibration of the engine, reduction of engine braking which is too strong, and entry of the corner becomes easy.

You can also experience the improvement of torque as it is smoothly improved at the time of low rotation or as if tuning the engine.

We recommend cleaning cleaning every time the engine oil is exchanged.

When the oil mist from the crankcase passes through the internal pressure valve, mist adheres to the extraordinarily small amount.
Excessive adhesion will hinder the movement of the valve and in the worst case will cause valve sticking. We will restore the original state just by cleaning the interior of this product with a parts cleaner, so we recommend cleaning every oil change.
