The part number, 5RL, is correct for about the early '80s. I didn't remember the tips protruding quite so far, but they were noticeably long. As I recall, they were only used for a short period of time when Harley was building bikes that would barely idle even when brand new due to the way they were tuned to meet emissions.

thank you lee, regards jib
