RB inlet manifold

[eibargum]

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

Cost? Where to order from?

[martints1]

Hi,
...the manifold will cost around €100-120,00 exkl. p&p. Send me an email to ts1_mg@hotmail.com
cheers Martin

OK, cool.

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

...I have problems to post the fotos - can you do that for me ? thanks Martin

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...

Martin [corrado], are you going to adwick [doncaster] parts fair tomorrow and if so have you got a prototype of the cast inlet you can take for me to have a look at. i have a spare RB22 barrel and piston and iam looking to buy an inlet for it, hopefully new and inproved , regards, gary.

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.
