Yes the prices are a bit rough. I found these while looking for a twin Carb manifold for an a15 oval port. If i get desperate I might have to buy one off him. First thing is I need to buy is some carbies.

It's the second one of the single carb (Lynx) that i have, mind you it only cost me $65! It's new too, but i don't have a carby for it yet. Just trial fitted it with one of my twins!

How are the prices on those two single weber manifolds $260 ,talk about price gouging.

Is this the Single Carb manifold you mean?

By they way I am in no way connected to the seller. I just saw these and remembered your post. Good luck.

The single sidedraught weber manifold for a 1200 seems to fit OK you just need a relly small (short) filter on the inlet to clear!

I have one with a single downdraught and it goes really well.

A single 40mm would be great but the manifold might be hard to find.

I have twin 40's on my 12oo and they bog a bit a low revs but I am happy with the set up

they would have to by little webbers,
the 1000 doesn't suck much wind...
the Hitachi of a 12 or 1400 will be a decent upgrade, or even a DGV..
