Valves for YBB321 horn
Posted: Tue Jan 30, 2018 4:14 pm
I found a YBB 321 horn for sale that seems fine except that it's missing the valves! Does anyone know where I can buy these or has some so I can fix up the horn?
You can probably buy them, and you can put new-style pistons into an old-style horn, but to get all 4 with all the doodads and with lapping is gonna cost a lot.
They have one or two really annoying flat notes, and if you overblow them it sounds bad in a hurry. But pretty much everything else you could ask for is moderately positive so it could be worth doing.
