Knucklehead

My favorite Harley is the mid thirties 61c.i. Overhead valve E or EL models offering sporty 1000cc of engine in a beautiful machine. Engineering detail which epitomized the technology of its day.  

 
The very distinctive valve covers give the bike its unofficial name looking like a clenched knuckle.

  
A period article extols the virtues of the good oil supply used to cool these power thirsty engines.
