Yes that's a great bit of Honda History...thanks for posting. Think I may have seen something on FB about it ..not sure....quite a few idiots on there so I tend to skip over a lot of it.
It's scandalous IMHO that a lot of info is regurgitated from the SandcastOnly forum site but that site itself is almost dead now as nobody seems to post any more..
For anyone new on here myself/Bryans collection of 750 Service Bulletins is in the Dropbox links and repeated below in the link.
(the full article is several pages long)
https://www.dropbox.com/scl/fi/es60umd6www1zopg1d081/CB750-Service-Bulletins.pdf?rlkey=8pcvif5mepwzxyjrdidr2cvar&dl=0Last year I bought a spiral bound copy of the Bulletins off eBay (upto about #20) and there are a couple in there I have never seen anywhere before. In due course I will scan and add them and this letter too.
The recall for chain breakage is in the link above (#32) ..a screenshot of the first bit is here.
