Motorcycle camshafts are revolving shafts along with attached cams, which are often regarded as lobes. For the four-stroke engine, its camshafts are located along the lobes while the cylinders are connecting to the valves. Motorcycle camshafts in a normal engine look similar to a teardrop, with the slim end protruding while the thicker end connected to its camshaft. Both lobes and shafts are made of burly metal, typically steel or iron. Here are general motorcycle camshaft replacement tips.

Four-stroke Motorcycle Camshaft

Remember that for camshafts found among four-stroke engines they need a means for closing and opening valves. On the other hand, two-stroke engines do not require camshafts since they are emitted by reed valves or a corresponding hole incise at the cylinder’s side. Since motorcycle camshafts turns, the cams thrust against something. For a car engine for instance, the something referred is normally a valve. However, with older model cars, the something is the “mechanical fuel pump lever.”

Camshafts are replaced directly over the valves or directly opposed to the valves. They are arranged further away, where in case a push rod can perform like an extension. Motorcycle camshafts are operating in combination with the water wheels and automated drum machines.

Dirt Bike Motorcycle Camshaft

The usual design of camshaft is the single overhead cam (SOHC). This cam is a metal shaft. Sooner than being a standardized shaft, although, it features lobes which assist to close then open the valves.

Motorcycle engines with camshafts are known as four stroke engines. The cylinder head of the engine is the part which bolts down above the cylinder then forms a seal. If you replace the piston of the motorcycle camshafts, it should be mounted on top of the cylinder located at the cylinder head’s interior.

Every time the piston shift upwards or downwards at the cylinder. The valve usually opens and closes accordingly. The parts which organize the valves’ closing and opening are cams along the camshaft. Since the motorcycle camshaft revolves, the lobe comes along every revolution. Every time it does, the camshaft pushes away from the lifter along the valve stem’s base then makes the valve open.

Camshaft’s Valves Maintenance and Repair

In general, if you are replacing the motorcycle camshaft, you need to consider the lobes, which are in various combinations on the four-engine strokes. Meanwhile, for the intake stroke, in which the piston is going down to give ample amount of air mixture and fuel; the cam’s lobe is intended to work on the intake valve, which is turned in order to press against the lifter located at the intake valve stem’s base. It unlocks the intake valve to let the piston draw the air mixture and fuel to the cylinder by means of the unlock intake valve. This is something to watch out for once you are doing motorcycle camshaft replacement.

The motorcycle camshaft is an essential metal shaft divided by sections in its length which are out-of-round. The out-of-round sections are regarded as the real cams which function to push the valves open every time the lobe side comes around to its rotation. These are significant considerations in general while replacing the motorcycle camshaft.
