Known Issues
|
|
Panhead Oil Leaks:
|
Panhead engines are known for minor oil seepage, which is often considered characteristic rather than a defect if not excessive.
|
|
Carburetor Tuning:
|
Linkert carburetors can require precise tuning for optimal performance and can be sensitive to adjustments.
|
|
Electrical System Reliability:
|
Older electrical systems can be prone to issues due to age, component wear, and potential modifications.
|
|
Drum Brake Performance:
|
Drum brakes, while effective for their time, offer less stopping power and feel compared to modern disc brakes, requiring diligent maintenance.

Model Evolution
|
|
Panhead Era:
|
The Panhead engine was introduced in 1948 and produced until 1965. The FL Electra Glide, launched in 1965, represented the pinnacle of Panhead touring motorcycles, incorporating the iconic 'batwing' fairing.
|
|
Shovehead To Electraglide:
|
The FL model evolved from the earlier Hydra-Glide and Duo-Glide, with the Electra Glide designation and the large fairing becoming synonymous with the top-tier touring model.
|
|
Transition To Shovelhead:
|
While this manual covers up to 1969, the FL model platform transitioned to the Shovelhead engine starting in 1966. This manual likely covers early Shovelhead FL models (1966-1969) as well, if they retained similar FL designations and shared many components with the late Panheads. (Clarification on exact engine coverage for 66-69 would be ideal from the manual itself).
