I had an old Knuckle head that was a ***** to start. Would throw me over the handle bars sometime. Gotta get that kicker just right.Hubby owned a Harley once a long time ago. He broke his leg kick starting it. Apparently, something gave way in the starter or something (haven't heard the story for a long time) and his leg flipped forward...broke his knee. He sold it and never had another Harley. All Hondas and Yamahas since then.
