That's possible - i'm starting to think the calipers were from another model. I have no rubber boots on my 750 (i do on my 550, so i know what you mean.) well, rather than buy a 2nd new caliper, i'd rather ust get the right pads. do you think trying an earlier year, such as a '74 CB750 might help? i'm in the dark on this one. Thanks
