Internal pressure control valve (for Triumph Street Twin)
Reduce the feeling of glitter and realize smooth running.
When traveling, the interior 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 inner pressure control valve keeps the crankcase internal pressure proper by mounting it, reduces the engine vibration and reduces the engine braking which is too strong, makes the entry of the corner more comfortable, and makes the feeling of shocking the accelerator on and off at low speed Various merits can be obtained, such as smooth improvement and experiencing improvement of torque as if engine tuned.
Since the breather hose is also included as standard, it is an easy design that can be installed simply by replacing it with the genuine part.
We recommend cleaning cleaning every time engine oil is exchanged.
When the oil mist from the crankcase passes through the internal pressure valve, the mist adheres to the extraordinarily small amount.
If it adheres too much, it inhibits the movement of the valve, which in the worst case will cause the valve to stick. We recommend cleaning every oil change or every 6,000 km so it will restore the original condition just by cleaning the inside of this product with a parts cleaner, etc.
