I saw one of these run again recently . . . and this will be the next thing I want to get. I remember watching a field of 15+ H-D Sprints at full speed on the Davenport 1/2 Mile years ago, and this brought it all back.
Dad's "Harley Tool Drawer" has lots of weird tools, pullers and pushers that we know work on only one type of engine - The H-D Aermacchi Sprint ! Bonus ! That big bulge on this side of the engine case houses the magneto . . .
