It reduces the jerky feeling and realizes smooth riding. When running, the crankcase is pressurized by the high-speed reciprocating motion of the pistons. This excessive pressure becomes a great resistance to the piston movement and causes various adverse effects. By installing the internal pressure control valve, you can keep the crankcase internal pressure at the right level, reduce the vibration of the engine, reduce the excessive engine braking and make it easier to enter the corner, improve the jerky feeling when the accelerator is turned on and off at low rpm, and experience the improvement of torque as if the engine was tuned. You can feel the improvement of the torque as if the engine was tuned. The breather hose is included as stock, so it is easy to install by simply replacing the stock part.
It is recommended to clean the engine at every engine oil change.
When the oil mist from the crankcase passes through the internal pressure valve, a very small amount of mist will adhere. Excessive adhesion will inhibit the movement of the valve and in the worst case will cause the valve to stick. It is recommended to clean the inside of this product everytime you replace the oil or every 6000km riding because it can be restored to the original condition by cleaning with parts cleaner.
