Drag racing history, part 1

Pretty much anything not covered by the topics above. Short lived production bikes or vehicles, Electrical, Tires, Paint, Brakes, etc. Use this for tech questions, and "Shoot the Bull" for general conversation, no tech.

Seen it before & it's really great reading, too bad you can't see larger versions of the pics though...

I ran a pretty fast 61ci Knucklehead that I stroked to 68 inches with 80 inch flywheels and 74 inch barrels and pistons.

Shows how with age, memory overcomes history...
He's "remembering" and combining details of 2 different motors.

It's possible, but I don't see how those contradict the statement.
EL with 74" wheels: 3-5/16" × 3-31/32" = 68.4" (pretty common)
EL with 80" wheels: 3-5/16" × 4-9/32" = 73.8" (this is the original U/UL bore and stroke)
EL with 74 barrels and 80" wheels: 3-7/16" × 4-9/32" = 79.5"
