Am I right in thinking that the short manifolds only work with split FCRs, and that the split FCRs have to be bought seperately rather than splitting an existing set of dual FCRs?

TIA

yes you are right, for single FCRs, you need short manifolds, from either
Malossi or Jako Motorsport, or you could re-work and re-weld your stock
manifolds as i did.
yes you don't split dual FCRs, as it would be too expensive, shops like
Kämna charge ~300 Euros for the operation.
You are suggested to buy two different carbs anyway, a downdraft for the
horizontal cylinder and a standard side draft one for the vertical cylinder.

cheers

Thanks, might be worth going the Kämna route. 2 single FCRs in the UK are around £1000/1150 Euros :(

get them in the US of A, from california cycle works' chris kelly in example,
as i said, rear cylinder is calling for a side draft carb.

:think:

on the other hand, you could sure buy a 4 piece Keihin bridge from any
japanese bike and have them re-worked for single usage yourself.

:think:

39mm is cool for a streetbike, opinion of others may differ.

If you go with the individual FCR's on short stacks, you can eliminate the fuel pump since you will have a gravity feed. You would also be wise to shut off the fuel flow whenever you park the bike for the day. I did this mod with my '96 SS/SP and it was a significant power increase.

Chris doesn't do split singles any more. I asked about 5 months ago

Can somebody educate me on the short intake manifolds?

I've seen Malossi mentioned dozens of times, and I see above that Jako Motorsports out of Germany also makes a clever design.

For a 900, which ones do I need to be getting to do Split Single 41's?

If you eliminate the fuel pump you will run out of gas at about 1/2 tank. Unless you cut the fuel tube that connects to the pump outlet near the bottom of the tank. Depending on the inlet needle size you may have to go bigger for a gravity feed system. The Malossi manifolds work fine but it helps to match them with the ports as the castings vary some from the stockers.

Which Malossi intakes? (Where can I order them? I've only seen a set available through bevel heaven)
