Only honda made a cb750. I think the info that was being requested was the model of the bike. Is it an F or a K?
I can't say for sure on the dohc bikes if there is a difference. On the sohc bikes, the f and k are virtually identical for center stand mounting. On the sohc, you disconnect the spring holding the stand up and then remove the 2 bolts holding it on and that is about it.
Your bike may be similar. Question though. Why are you removing the stand? I understand about the weight but is there any other reason?
I ask as what if you get a flat out on the road? You will have no way of taking the wheel off. In the garage, you would want to have something to lift the rear up to make oiling the chain easier and some other work.
Just want to give you a couple thing to think about. If you already have and still want to do it, go for it.
The ride IS the adventure. The destination is just to get gas!
