In search of the obsolete valve.
« on: June 09, 2015, 01:18:14 PM »
Howdy, I'm sure this is all for nothing but here we go. Does anyone have a source for the RH sub exhaust valve for 94 250? I'm sure not I keep getting the typical run around and email returns for "discontinued" how about 12005-1243? The 96 cylinder valve, I could make it work but can't find those either. Anyone got any good ideas??? It's the last piece I need....

I had a set on eBay that sold in about 3 hours.
I like that 94 cylinder..

I've heard from a few kx fiends , "buy a loaded cylinder, then resell the unloaded cylinder"  :wink:

Yeah that's gonna have to work. Just hope the loaded cylinder has a seller who knows what they looking at. It would be my luck to find another one with broken valve.

The 99-04 valves are a smaller diameter and I have been toying with the idea of sleeving one up to suit a 93 cylinder. Although I also have a 99 cylinder so I should just use it. If I ever try it I will post the results.

My left side is good, it's the right one I found broke in half. I was thinking about making some kind of mood and casting new ones. I don't have any experience but I figure if I can cast bullets...... It would be a bad thing to fall apart though

What material is the valve made of? Mild steel? Wouldn't it be possible to just tig weld it together.

Seems to be aluminum. I'm missing top half. Previous owner apparently couldn't find one either so he put half of it back in cylinder... Dumb. And of course didnt see until tore into top end.
