Correct Horn & Bracket?
« on: June 17, 2022, 02:51:20 PM »
Would someone have a drawing/picture of the original horn & bracket for a 75 CB400 please.  Mine is unoriginal with a made up bracket so I’d like to replicate the bracket as near original as I can.

I also see the mounting holes in the frame for the horn bracket are 8mm, the loom strap bracket has 8mm holes in it but parts description is for 6mm bolts - I see the horn bracket has rubber grommets & dowels that take the bolt fitting down to 6mm but the rest are just too big (8mm) by my thinking - am I missing something?

I’ve seen posts (here) that say the horn is a Mitsuba MB-E but other posts say something about a “plastic” shroud on it - what is right please?

Thanks - Bruce

Two types of horn and different bracket fitted to the 400 four  ;)

Bruce, if your bike is a UK one then it is indeed a Mitsuba horn according to the parts manual (‘E’ is the English version). And yep, there is a snap-on black plastic shroud.

As for the mounting… I can’t remember as recently sold my F2, but does the parts pic help?

Cheers…

Thank you all - smoothoperator, those photos have helped enormously - at least I now know what I’m looking for! My parts diagram doesn’t show too much detail around the bracket so I can now modify/make one up to suit
