Abstract
An engine having an oil circuit and method of communicating oil within an engine are disclosed. The engine includes a crankcase, a pump, and a camshaft having a first channel extending between first and second ends of the camshaft, where lubricant is provided from the pump to the first channel at the first end and communicated by way of the first channel to the second end. The engine also includes a crankshaft, a second channel communicating at least some of the lubricant delivered to the second end of the first camshaft to a crankshaft bearing, and a third channel within the crankshaft that receives at least some of the lubricant communicated by the second channel and communicates at least some of the lubricant to a crankpin bearing on the crankshaft. In some embodiments, lubricant is communicated by the third channel to an eccentric bearing configured to support a balance weight.
