I wish now I had kept the serial numbers but it was a 73/74. Lengthened swingarm, moved foward Curnutt shocks, plastic tank, air forks everything done to it that would make it worthless today! Post some pictures of yours. A number of years ago I put my riding buddys CR back together that he had when I had mine. Could not believe how loud that thing was,didn't remember how loud the exhaust was or how loud the straight cut primary's were. Here a picture of one of my current rides,not quite as powerful but still not bad for what I do now.

Here is another vintage picture and one 20yrs later in the same spot with another current ride
