Could be. I got mine in a million pieces and restored it myself. I don't know how they shipped things back then but the engine should have been in the frame from the factory not installed at the dealer. Things were still good in 69, I own a 69 650 that has always been trouble free. I have a couple 72 Bonnies that I had problems with though.

I learned all I need to know about life by killing smart people and eating their brains.
