will a set of carbs off a 600 be ok on a 2ltr

or would a set off a 1000 be better

cheers nige

Best way of working that out is to look at the cubic capacity of the engine they came off multiplied by the rpm of that engine. That'll give an idea of airflow through the carbs. If they're similar it'll be alright, if the CC*rpm is lower for the bike engine go for larger carbs.

On the other hand, someone might have already trod this path and be able to give a simpler answer.

What power are you aiming for? What size carbs from a 600? If they are 32mm and you're aiming for 250bhp then they probably aren't suited. If they are 36mm and you're aiming for 150bhp then you're onto a winner.

its a stock red top
not looking to go racing
the carbs are 36mm of a yzf 600

I think most folk with 2.0 engine try to get something like a 38 - 40mm like ZX9R, R1 and so on (GSXR1000 ? )
bogg bros sorted me out with ZX9R's for my 2.0 pinto with a fast road cam (since upped to a 2.1, but still within the range of the ZX9R carbs) - I just need to get it running before I give any more advice (Jacko has a similar setup to me though)


but if your not looking for all out power then the 36's will do the job - I know there are a few folk on here running this size on 1.8 / 2.0 zetec's / pinto's and the like...

(given the choice I'd go for the bigger ones though )

Don't go too big with carbs though or you'll get poor fuel atomisation, fuel pooling near the inlet valve and poor mpg (without necessarily any increase in Bhp). Throttle bodies are more forgiving as they don't rely on the venturi effect and choking for atomisation.

Hi,

I have fitted Suzuki 1200 Carbs to my 2.0ltr Zetec, drilled the mains out to 1.5 mm and it runs very well, it gives me 45MPG when I am not too enthusiastic with the go pedal but seeing I do most of my driving cruising then it is fine for my needs.

Regards

Bob

Only issue is the BSFC of the bike engine and the target engine are likely different meaning that working on BHP isn't an exact thing.

I have fitted zx9 carbs via a Bogg bros manifold to my Vulcan cross flow engine and didn't have to do anything else.
The difference to the 40 dcoe's is spectacular, instant reliable tickover, pulls cleanly form nothing to max revs, and much better fuel consumption.
The only thing different was the carbs were already dynojetted.
I have just had the car MOT'D and the emisions were spot on.
Reagrds Denis.

what did you pay for this "bolt-on" conversion?
