Oil Type Specification:
Refer to manual for specific viscosity (e.g., SAE 50 or 60 for air-cooled V-twins of this era)
Oil Change:
Refer to manual (typically every 1,000-2,000 miles or seasonally)
Spark Plug Replacement:
Refer to manual (typically every 5,000-10,000 miles)
Tune Up:
Refer to manual (recommended annually or every 5,000 miles, including ignition timing, carburetor adjustment)
Primary Chain Case Oil:
Refer to manual (typically a specific Harley-Davidson primary fluid or gear oil)
Brake Fluid:
N/A (Drum brakes of this era are typically lubricated, not fluid-filled for actuation)
Oil Leaks:
Common in older Harley-Davidsons due to aged seals and gaskets. Manual covers seal replacement.
Carburetor Adjustment:
Linkert carburetors can be finicky and require regular tuning for optimal performance. Manual provides detailed procedures.
Generator Charging:
Generator systems can be less robust than modern alternators; manual covers testing and potential replacement.
Pushrod Tube Leaks:
A common area for oil seepage on Panhead engines. Manual details replacement.
Founding:
Founded in 1903, Milwaukee, Wisconsin, USA.
Reputation:

Electraglide Introduction:
Introduced in 1965, but the 1964 model is often seen as a precursor or a variant leading into the full Electra Glide designation, building on the FL series.
Panhead Era:
The Panhead engine was produced from 1948 to 1965, with the 1964 model being one of the last of this engine family.
Manufacturing Location:
Milwaukee, Wisconsin, USA
Production Period:
The FL series, including variants leading to the Electra Glide, was in continuous production through the 1960s.
