EFI to carb conversion

More than is economically feasible. Ignition would be the biggest issue never mind trying to control two carb slides. The custom cabling would be a bear as the older systems with the plastic cable splitters never did work well. My suggestion is find someone that can set up the FI correctly and you will have a bike that runs well.

I second that... but the conversion has been done a few times over the years. You can let the ECU handle everything, and just adapt carbs. If you want to eliminate the ECU, it gets infinitely more complex.
 
Hmm interesting.
I really, really hesitate to disagree with these experts but I've just converted a '98 Cali EV from EFI and found it quite straightforward and really did not find it to be "infinitely complex".
Ignition was a simple matter of fitting a Sachse-Electronic CDI on the crank and as to "controlling 2 carbs", all that's needed is a small modification to a Daytona 2C throttle and cables to length. The choke system can manage quite happily with an old fashioned cable splitter.
My process:-
-remove the EFI, fuel pump, fuel filter and EFI related wiring, re-wire stand cut-off switch
-install CDI on crank with dyna coils, route wire from CDI module to tach
-fit 40mm pumpers with Daytona 2C throttle, new start/on-off switch, carb cables to length
-match stock choke cable to carb's with cable splitter
-blank off cam and flywheel sensors

Took me only a week as the wiring system appears to be a Cali carb layout with EFI grafted on so, conversion was straightforward i.e. simply removing EFI related wiring. The remainder of the wiring (generalising here) manages the bike's non-EFI systems quite happily.
I've done several hundred miles now with no apparent issues. (mind you, I still have my fingers crossed)
I'm no ace mechanic but, as I say, none of this was particularly difficult or expensive.
Disclaimer:
On the other hand, my experience with Todd's EFI re-flash and the PC-Autotune on my Griso tells me that a well set up EFI is a joy to ride
and the EFI re-flash/Power Commander would certainly be the cheaper option for your Jackal.
My mods to the EV were founded on a love of old-school simplicity, owner tune-ability, lack of frame clutter and roadside fixability so may not relate to what you're looking for anyway.
N.B.
Please, please!
No comments about the ruining of a perfectly good EV (take note 'The Groper'!)
 
Thanks for the info. I think I will stay with the fuel injection and give it a try. I am converting a Jackal to a cafe racer style and drastically changing the intake and exhaust. We will see how it goes.
 
No problem. Here's the before and after pics. Come to think of it though, it was a bit pricey what with carbs and CDI. The mid valve 1100 is one sweet engine!

Be interested in hearing about your 'drastically changed intake/exhaust'.
