The wisdom of senior citizenship (yeah, I said it) tells me I should have stopped by Ruttman Kawasaki just to introduce myself. Duh.
I know one of them was a very good fabricator, and found some enhancement opportunites in the chassis and other places, but generally the Kit Kar was quite good handling, and that may have been its primary strength.
But, it wasn't very long after the introduction of the Howe chassis that any production based racer was moot in most racing circles.
