Back then, nobody called it a Knucklehead yet. It was simply the \"61 OHV.\" It was also Harley's first engine with a recirculating dry-sump oil system, the start of a new era.\u003c\/p\u003e\u003cp style=\"color: #334155; font-size: 15px; line-height: 1.9; margin: 0;\"\u003eThe first year was a year of constant change.
