I have a Honda bulletin in JPEG form that I got from a web site in past years. It's a 532 K JPEG, so I can't post it here. It's dated December 8, 1976. Tittled CB750 Clutch noise Update. It also says the factory fix was put on engines with numbers higher than :
CB750F E #2557523
CB750 E 2700014
Nice pictures with assembly order and all the part numbers and such.
Seems like it should be in FAQ somewhere but I don't know how to do that.
Where should I send it?
