| + | The design of the frame changed in 1973. 1972-earlier used a heavy rough casting where the top tube and the vertical rear tubes meet. \\ | ||
| + | The 1972 and earlier frame tubes are canted at an angle of 10° where the 1973 frame tubes are at an angle of 9°45'. Not a great difference but still different. \\ | ||
| + | 1973 did away with the casting. \\ | ||
| + | And used what looks like lightweight welded strap metal with an angular bracing running from the rear engine mount up to the end of the fender supports. \\ | ||
| + | But a greater change (apart from the casting elimination) is the distance between the head tube and the rear vertical tubes. 1972 = 28.42", 1973 = 29.04". \\ | ||
| + | Even though the 1972 frame head had a greater rake angle (30°) the 1973 rake angle was less (29°35') the distance to the rear tubes is greater.

| + | L73-78 tanks are notched on the flange between the top bolt holes. This notch allowed HD to raise the tank position. \\ | ||
| + | Raising the tank meant that both the upper and lower mounts were changed (new upper mount - 62554-73 and new lower mount - 62555-73). \\ | ||
| + | In 1975, a ridge was added to the inside of the filler neck to retain the filler cap better. The L73-78 bottom mount is taller for the raised tank.

| - | Triangle shaped side, battery box built into it. Drain plug (704) on (R) bottom of tank. \\ | + | Below is an after market version upper oil tank mount from Legends Motorcycles showing how the upper mount changed. \\ |
| - | Oil filler neck is shorter than the -80 tank. It's not clear what the actual oil amount is for the tank. \\ | + | There are two mounting holes running front to rear to attach it to the frame. \\ |
