Cb750k8
« on: November 29, 2025, 04:06:04 PM »
Hi everyone, just registered on the forum as I've got a 78 cb750 which was my first big bike when I passed my test back in the 70's. Looking forward to chatting to you guys as I know I'm going to need assistance keeping it running right. (It's a U.S. import so it's not going to be straightforward)
Replying to laverda Dave, (please bear in mind it's only going to look better from this point forward)

For those of us who name our bikes, yours is clearly “Kate”.

Just spotted a genuine Honda shop manual for the CB750 K8 and F3 on eBay - might be of interest?
Ebay item number is 406419338743

If you look in Ashs dropbox you will find it there for free

Certainly of interest to OP, from images its possibly original as it shows some fading in slightly yellow colour that would be grey on copying.

I have an original here, in its official Honda workshop ring binder to compare. Not fir sale.
