Hi,
i found this site when I searched for other aircooled-WBX builders.
Very interesting Thread !
I'm building an 76,4x103 engine with Limbach Heads an 42/37,5 Valves.
Here are some Pics:

One says, you can't use bigger bores than 96mm, or bigger Valves than 40mm.
Yes you can ! I'll see how long it works. I heard about an 82x103 engine that works great !
Greetings from Germany,

Welcome to the STF!
VERY interesting pics!

Are those modified T4 jugs?

Thanks !
I dont know what "jugs" means, my dictionary said it means "tits"
If you mean the cylinders, yes they are !

The water-to aircooling modifications already were done when i bought this parts.
The previous owner had two many projects, so he sold them.
However, I think the combustion chambers still need some work. As you can see on picture 48 theres an edge
on the valve seat. Needs some welding I suspect.

If anyone wants some detail-pics, of the case or the heads , tell me.
Maybe I should open an own Thread !?

Very nice, I'd suggest smoothing the sharp corners in the combustion chambers.

Not sure how well the cylinders will cool, being so close together.
Air flow between the barrels will be kinda limited.

Oddly enough, that's exactly what I said when I saw your pics!
(slang=="great")

I'd definitely start your own build thread, you have a very cool project!
