BMW Motorcycle Camshafts, Lifters, & Parts

Camshafts are essential components when it comes to ensuring that your motorcycle's engine runs right. As the name indicates, they consist of two distinct parts: a cam and a shaft. Together, the activate the cylinders' intake and exhaust valves.

What Do Camshafts Do?

In a typical four-cycle engine, the cam is connected to the crankshaft by a timing belt or chain. That keeps the cam's position fixed in relation to the engine cycle. The cam's lobes push the valves open, while valve springs push them closed. Since the transfer of motion could be too powerful for the valve stem to bear, wither a tappet or rocker arm is used to transfer the motion.

How Do You Recognize Bad Camshafts or Lifters?

Camshafts are usually made from cast iron or cast steel blanks, though custom and performance parts may be milled from a solid block of steel. While their construction makes them less likely to crack or wear out, they still can eventually begin to fail. Signs of trouble include:

• Misfires or increased emissions due to worn cam lobes
• Clattering or tapping noises from the valve covers, a result of worn cam lobes
• Broken camshafts can cause engine seizing
