Re: What does spl stand for?
Yep, SPL stood for Special. They were offered with fewer features. In addition to lacking the oil injection, they often lacked power trim, and had less fancy cowling graphics. In later years, they were often the "old tech" models alongside a newer tech motor of the same horsepower, .ie the old crossflow 88 being offered at the same time as the newer 60-degree looper 90s. Basically, they were made to hit a price point below the premium models...
