Martin, any idea when the cast ones will be available.

...I think my manifolds (shown in the link to GSF) should be ready to order in 10-14 days ! cheers Martin

OK, cool.
If you do a proper post in dealer innovations etc, you might pickup a few sales etc.

Ah, 2 Martins with conflicts of interest. Which is good for the customers. My supplier is casting them so should be cheaper than CNC, but the CNC will look nicer. He's testing a prototype so hopefully they won't be long.
I've got the cast versions for the TS1, they're about £70 plus P&P, including the bolt on rubber connector.

...the TS1-version is cheaper as the RB-version, because it is smaller (less material) and didn´t have a stuffer as the RB-version...

This is what Madmaex was talking about from the german forum on the previous page.
Nice. I respond better to pictures......
Some of the design issues with the RB manifold are to do with AF trying to avoid a patent issue with Tassinari's V-Force reed valve, making the monifold a bit of a compromise. If you look at the Worb RB engine from a recent issue of scootering (it made really silly horse power, but looked all-but unrideable from the dyno graph) they took out the AF reed and inserted a traditional V-force item. As the engine made 40+bhp, there is no doubt that the Tassinari flowed as much (if not more) than the AF Reed.
I can see that Worb's choice might be driven by a desire to maintain the velocity of the incoming charge. I believe that the standard RB inlet manifold does little to assist this. I also think that AF may have noticed this, and realised that opening-out the manifold to the full length of their own reeds would hamper this further.
