Pushrods are part of a motorbike's engine management system and are used to transmit the movement of the camshaft to the valves. The tappet cups are located on the camshaft and are pressed by the cams, while the rods are connected to the tappet cups and transmit the force to the valves.
The tappet cups are often made of robust metal and have a cylindrical shape. They are used to convert the movement of the camshaft to the linear movement of the pushrods.
Correct adjustment of the pushrods is important to ensure correct valve clearance. If the valve clearance is too large or too small, this can lead to inaccurate valve timing and loss of power. The pushrods should therefore be checked regularly and adjusted or replaced if necessary to ensure optimum functioning of the valve mechanism.
