Quick and dirty. Set the Kohler down to see how it'll look. I need to cut off all the unnecessary tabs and mounts, and then weld in a piece of plate. Once I have the mount holes marked and drilled, I'll put support bars under it as well.
The Kohler takes more space than I thought it would, but that's ok. At 88 pounds the Kohler is still lighter than most bike motors I think. Gonna work on minimizing the frame this week. Also still hoping to pick up the girder tomorrow.
