Need assistance. Left side horn not working. Eeks out a weak meep on the right.

'81 XS1100 Special.
Figured I'd pluck the minds of the gurus here for solutions. I've tried sanding contacts. Switched 'em and the other operates on either side.
Replace or repair?
TIA

Replace them. That is what I did on my '79SF. I bought an airhorn that is all one unit. Mounted on the left side of the fairing bracket. VERY loud, as you need down in AZ. Yes, I've lived there for a year, with a motorcycle as my transportation.
The horn is a Denali Soundbomb Compact Air Horn from Revzilla. It's about $63 now, and it is LOUD!. Makes a big difference as a car is trying to get into my lane without looking!

Take them apart and clean them. They are probably just full of crud. I had to do that on two of my bikes. Once cleaned they work like new again.

Well I don't know what you would take apart... Seems to be a sealed unit.

If I remember correctly, there's a screw with a lock nut on the horn somewhere. turn it a little one way or the other. I don't know what it is for, but Mine started working normal after tweaking the screw.

I'll give it a shot.

Take the nut and washer off the front. Spray some lubricant on the plate underneath and let it soak in. Might need to do this two or three time and then blow them off. The crud I spoke of is built up under that second plate under the top metal cover. It can't resonate because of the crud under there. The horn works by that piece and the top piece vibrating. Hope you see what I am trying to say. I thought mine were gone to, but after doing this they worked.

There is also a small Phillips adjustment screw with a tiny lock nut on it. Sometimes turning it in or out will fix it.
