Title: CB400 Horn
Post by: waffey on March 04, 2018, 06:36:56 PM

Hi,

still stripping the bike. I've taken the horn off, tested and it works. Worth keeping but de rusting and painting or buy a replacement. Are they scarce?

Very scarce, especially ones that work! I gave up trying to find one and fitted an aftermarket part.

I managed to find 2 recently. One wasn't working but had the original plastic cover on it and the original bracket. The other was working and had a cover but a very rusty bracket. I made one good one out of the pair. The spare plastic cover is on eBay at the moment. The one in your picture Waffey doesn't look like a CB400/4 horn.

I assumed it was original (never assume)

this is what I've taken off the bike. Last MOT'd 1997. If its not the correct one then i'll just get an after market one

Yours looks the same as the one I had on my 400. Mine was also fitted to some strange bracket, looked like it came if a car !!!!

Bought a cheapo one which was far too quiet.
Knocked up a new bracket in the same shape but in stainless, looks nicer.
That horn looked cheap and wrong so I sourced a plastic cover on ebay and boiled the horn in washing powder (someone else discovered this not me) to clean and encourage it to work.
After a bit of adjustment it worked !! 
Eventually it got painted too.

A lot of horns are not worth the effort these days, the old honda horns were/are great, the type originally with my 350/4 really can be heard, i sourced a non working pair stripped and cleaned them, cleaned the contacts and put the low tone one on my z1000, and the good thing about them is they are assembled with screws.
