By the VIN it is a 1972-73, and that is odd that K5's were both years, I think, 5,000,001 to 6,000,010? This one is E#- CL450E 5013664 and F# CL450 5013630, #'s pretty close together I think. Seems I read in a discussion that they were almost never the same and not usually close to the same. I am still struggling to post pic's so I'll just describe it for now. It is basically a chopped off tail frame, a motor with no plugs,exhaust or carbs. It has a front end that looks like it has air assist forks as in what looks like an air line running from one fork tube cap to the other. Drum front brake and it rolls on flat tires. It has been sitting outside under a barn awning for who knows how long. I figure it must have some good engine parts and I'll use what I can and also use it as a teaching tool. I will work on the pic's.
