new carbs

[thecolonel]

As a few of you will know I drive Gammas
anyway, I've sorted the suspension, seats, bodywork and now I'm after POWER
in this vein I've thought about DCNF carbs but they don't like sitting sideways
that leaves IDF's but they are extremely rare and quite expensive, so I've been
looking at alternatives and I've come across a couple of race forums that are
quite keen on Keihin or Mikuni now these are bike carburetors and aparently
work very well with little or no adjustment only a couple of jets and enable
large volumes of air to be drawn into the engine.

So any Beta drivers that also ride bikes and have experience of these carbs.

I will add that I was thinking of a set of 4 carbs from a 1000 cc bike then simply
modify my manidfold and attach 1 per cylinder.

I think Keihin carbs are made by Honda (my Triumph Acclaim had apair of them!). Have to say that I can't see bike carbs having a sufficient throat for Gamma cylinders, weren't they the biggest in a production car at the time?

must admit I thought the same but at the moment I'm running an ADL38 which has quite
small chokes in comparrison to the bike carbs, going from two throats to 4 should be an
improvement although I can't be sure until I try it, hence the question.

This is what you need Geoff  



Start looking in scrapyards for an old Alfasud 1.5 Ti or even better Alfa 33 Cloverleaf (non 16V). And you'll need a VW Beetle throttle linkage

I agree Theo, but, having searched for some time, they are either ridiculously expensive
or require a full rebuild, whereas the bike carbs sell for about £40.00 for good s/hand ones

Well the new carbs are en-route 
4 Mikuni 45 degree angle 39mm slide throats same size as the inlet ports

may have to use them as throttle bodies with injectors as it is possible
they may be too vicious, from what I've learnt they're a bit all or nothing.

still could be a bit of fun, alternative is use two of them as carbs attached
to a supercharger
