Harley Davidson Adventure/Touring Bike Pistons, Rings, Connecting Rods & Components

Your iconic Harley Davidson is equipped with an internal combustion engine that produces power by burning an air-and-fuel mixture in its cylinders. To convert the power of expanding gases into rotational power, a set of pistons and connecting rods are used. Rings are added to the outer edge of each piston to fill the gap with the cylinder wall thus increasing compression and collecting excess engine oil preventing it from getting into the combustion chamber from the crankcase. Connecting rods, as their name implies, connect pistons with the crankshaft while also transforming their reciprocating motion into rotation.

In the process of their operation, piston rings are subjected to natural wear since they are always expanding like strings to be firmly adjacent to the cylinder walls at all times. Worn out piston rings allow portions of air-and-fuel mixture to seep into the crankcase causing so-called blowby. The piston itself could be burnt due to bad ignition timing. Even though conrods are constantly lubricated by the engine oil, they still wear out over time and can be bent and even broken during a critical engine failure.
