I've read many of the topics on the pros and cons of bike carbs over my existing 45 side draft dellortos and have now decided to go down the bike carb, not tb route. Which carbs are best suited to car use. I understand some can be re spaced without much trouble and I hope someone can tell me which ones.
I want to keep this as simple as possible as I intend to do the inlet manifold and basic jetting myself in true locoster fashion. Any advice would be greatfully received.

I have zx9r carbs

What size engine are you using??

Sounds like a lot of effort for not much gain to me - what's wrong with the 45s ?

Bike carbs V's weber debate....... Here we go.....
An experienced tuner who worked for Tolman racing and worked on a Caterham racer series says bike carbs are better as the veritable venturi delivers better flow characteristics, much better response at part throttle as the throttle butterfly may be slammed open by the large right foot but the veritable Venturi with the needle is raised only by the amount the engine requires.
Economy is better as well.

Can depend a lot on which engine you are using. For a zetec they are ideal and a cheaper option especially if you can make your own manifold. I made my own so I did not need to respace carbs but off the shelf items are available. Contact fast dan on here he may be able to advise you and supply what you need.

All good advice. BUT you need to be careful with jetting. Get it wrong=dead engine. A wideband O2 sensor is needed (or a rolling road)

I have ZX9R carbs and they are much better than the twin Weber 40's I had on before. Better fuelling, better throttle response, better economy etc....

I made sure that I had a mounting point for a lambda sensor welded into my exhaust to ensure the fuelling was bang on when being set up on a rolling road. I simply screw a spark plug into it in order to plug the hole when not in use.

My pinto now makes a very useful 174bhp at the flywheel and that's with just a piper 270 cam. There would be a bit more if I went to a 285.
