can anyone ID this strange head on my 250r?

[SatisTraction]

I bought a 250r last night and this head is on it. it looks like a custom engraving has been ground off but no other marks that i can see.

Looks just like an old gt thunder I used to have, where its ground is where mine said gt thunder.

FTZ had a custom head that looked like that, but that one your showing, looks like the one they offered for an LT250R Suzuki Quadracer.
