Can bike carbs be separated?
Reading the latest PPC mag the other day about bike carbs got me thinking. I've still not got my car sorted with megasquirt and if I switch to
carbs I could keep my EDIS setup, sell megasquirt, sell wideband lambda kit & gauges and have plenty of cash to buy a megajolt unit and some bike
carbs. Webers etc go for silly money, but if I can use bike carbs then that would be great.
In PPC it says for 2000cc engines 38-42mm carbs would suit. As bike carbs I've seen are in a row of 4 that's 1 carb per 500cc, as my
straight six is 3000cc that's also 500cc per cylinder. I've not seen bike carbs, but can any be separated & spaced at all so I can get
a row of 6?
Carbs listed in PPC that are 38-42mm are Honda Fireblade (CBR900RR/CBR919RR), Kawasaki ZZR600, Yamaha FZR1000, Suzuki GSXR750, Kawasaki ZX9 (ZX900
Ninja), Yamaha R1, Honda Blackbird. Could any of those be split? Or alternatively are there other bikes that use pairs so I could use 3 pairs?

Yes they can be split, but to extend them you would have to probably machine a through hole for butterfly shaft AND possibly fuel channel. Tis
feasible if you really wish to!

Yes you can
You need two Set's of carbs then remove the too center carbs from one of the Set's so you have
end carb -center - center - center - center - end carb

ZX6R carbs are 38mm and easy to seperate and tune.
If I had a megasquirt though I'd be buying two sets of TBs and seperating them.

if you can get away without respacing them its easier - but that doen't mean you can't respace them
not the cheapest but Bogg Bros. could easily sort you out: http://www.boggbros.co.uk
they are very easy to deal with and there work is first class
I got my carb's and manifold from them (2.1 pinto without respacing in my case)

Get 2 sets of carbs off a triumph triple, or better still keep what you have and two sets of TB's and do not seperate but build the manifold to
suit
Always cheap on Ebay ![](/images//smilies/smile.gif)

I re-spaced some CBR600 carbs - easy if you have a lathe to make spacers, etc. together with some experience in fabricating stuff from brass tubing
(e.g. silver soldering).
This is what I ended up with:

thanks everyone for the replies! Lots to think about, particularly interested in the idea of 2 sets of triumph (daytona) TBs. Means I'll have to
stick with MS though I think i need to rip everything out and start again from scratch
