Universal Engine valves for honda 125 cc

two primary valves: an intake valve which allows air-fuel mixture to enter the cylinder during the intake stroke, and an exhaust valve which releases the burnt gases from the cylinder during the exhaust stroke; both valves are opened and closed at specific times in the engine cycle by a camshaft, ensuring the proper sequence of combustion within the cylinder.
