Reese got us some pictures of this bike that I resized for him. It definitely started out as a 1958 Sportsman, as you can tell by the kickstart shaft that runs under the engine. This bike should have a center stand on the kickstart shaft. I also believe the engine to be incorrect, as it has a Wico flywheel. The external kicker looks like a "custom" change. LOL
EDIT: Looking closer at the kicker, that is an internal kicker; looks like it was mounted with a longer shaft and some spacers to push it out.
