Need a bit of advice really, i havent heard good things about webbers so im going to steer clear of them, i was looking into bike carbs as suggested however i am researching at the moment the how and why, i know i will need a custom inlet manifold which i have covered, just curious about results etc and whether i want non-vacuum carbs or vacuum carbs which mean an airbox assembly needs to be constructed.
Cheers.

throttle bodies are a bit more costly though warren and they require the management which is rather expensive as well i thought

hows that?
custom manifold for bike carbs will cost the same as for bike throttle bodies
a set of bike throttle bodies will cost similar to bike carbs 
what managment would you use with the carbs, megajolt?

i dont know apparently i can get away with ignition only management, the custom manifold is £200, ive been quoted £150 for getting them set up and RR'd and there are ZX10R GSXR & R1 carbs that go on ebay for reasonable money as well

well you can either use the standard management with the injectors still plugged in so it thinks its injector fuel still or use something like megajolt ecu to control spark only
£150 is a very good price tbh

hmm, well roughly speaking carbs are going to cost around £400 without management, i dont think i will manage to get throttle bodies for less than a bag of sand and it will probably need to be started at 5am sometimes and i didnt think that it would like that

carbs will be harder to start from cold tbh
will cost the same if you use bike throttle bodies
plus abit extra for fuel/spark management and abit more for mapping
if doing carbs i would get some twin 45's on the correct manifold

a similar project to what i would like to do in future used webbers but then changed to r1 carbs, they were a lot lot quicker, i will look into throttle bodies as i wanted to use standalone management anyway,

theres a set of zx12r bodies on the bay, is there anything in particular i should be looking for? i know tapered ones are better and then possibly saab injectors would be better as well with a decent map

you can use the bike injectors, saves making holes for injectors in manifold
i was thinking for r1 carbs earlier  not bodies
all you want the throttle bodies for is a tps sensor, butteries and throttle linkage and will adapt easierly to a inlet manifold, just look at the pics

do you know mr warren if the r1 carbs had/used a airbox or just had a large filter type thingy

no filters 
they angle up due to the design
best bet, get hold of that copy! think it gives you jet sizes etc etc
surely if you get a redtop with a dizzy you dont need any management.......

becasue you are getting rid of the standard ecu/injector system, i think you need a hall sensor is it? or sothing to pick up crank sensor
something is telling me you do, im sure iv looked into it before
make you own?
