Ironhead 77-78 foofoo valve find

hey guys for those of you with the 77-78 bikes...

I just ran across these and thought to share..

its the internal valve* replacement..

I have a new one, and a used one.. and just bought one of these to have n hand should it ever be needed...

I haven't seen these offered very often(or that I can actually remember without buying the whole set up...
