My motorcycle is now detected this piece of a problem, would like to first understand what the valve is used? Or its structure everyone who has? Thank you so!
This is really not heard, it may be your exhaust pipe back to the pressure of the bad bar, the root of the exhaust did not how much money
Is to control the motorcycle exhaust resistance, usually two red or large displacement 4 red car dedicated structure, the valve can be closed to increase the engine low torque, the valve can open the high turn power (because the exhaust resistance is low)
Variable valve is easier to understand, from the overall appearance point of view, like a simple throttle body, the system works in the exhaust pipe welding the variable valve mechanism (the valve installed in the exhaust pipe system The position is usually installed in the exhaust tail section), when the engine speed is low, the valve will be closed, so that the exhaust flow from the smaller diameter or single pipe discharge, keep the exhaust pipe back pressure, so low speed Torque is not lost; high speed when the valve will open, and the exhaust will be discharged directly through the large diameter or double pipe discharge, so that the exhaust has more channels and exports catharsis, and thus reduce the exhaust pressure back, so The success of horsepower will have a better performance.
