HonderCB: The extended sidestand was a take off just lying around. It came off a 74 750 with a 6 over front end which I put back stock. It is a stock stand that has been cut and lengthened. I have done it myself before. Just happened to be just right on my bike.
If you have interest in me measuring and estimating how much length was added, just let me know. Thanks, Stickman
