Hi i would like to know if a different carburetor can be adapted if venture and jet sizes are the same?
Answers:
No. The jet numbers are not always consistent. I always thought that the numbers made reference to flow capabilities, but apparently I was wrong.
The biggest problem I've run into is when using Dyno Jet jet kits. The numbers they use on their jets are very much unique and not even close to what Keihin and Mikuni use.
If you have the can CFM carb and the venturies are the same and jet size (Which can always be changed if needed) are the same then you should be fine. The biggest issue is will it bolt to the intake and will your fuel line mate up to it. not to mention if you will need to run the throttle cable differently, the kick down, the choke settings and auto choke. there are a lot of things to worry about when making an adaption of this kind. But yes it is completely do able.
My experience is that different carb makers number their jets differently.
As far a adapting, you can make almost anything fit, IF you want to devote enough time or money!
i changed makes of carbs on another bike i had an all i did was go to a local tunner and told him what i had standard and what i was changing to an he was able to find out the jet sizes i needed an get them for me.cost me £3.00 so didnt break the bank but i did get a dyno run just to check the mixture an running after i fitted them
