1915 Indian Race Motor by Ken Edmiston

Ken Edmiston was a prominent figure in motorcycle racing for the Northwest and West Coast, building specialized engines for racing and street use. He applied his talents to everything from early side valve configurations through manufacturing his own OHV heads. This engine started life as a Power Plus Single Engine, then modified with a later model cam chest, to facilitate a return oil pump and a later Chief cylinder. Upon inspection, this engine was found to have all modern bearings, a polished connecting rod, and what appears to be a custom made cam and a high-compression head.
