Tuning 45 DCOE Webbers/copies

How small of chokes will fit ? Replacing 36mm, injection,( 1250 cc Suzuki Bandit). My first choice is oem, but not available now.
I've heard that Webbers are about the most tunable carb's. ? System will stay I.R., so (2) DCOE's.
Suggestions ? Thanks, Art.

Mmm, there was an enthusiasm for putting triple Webers on the Triumph 6-pot.

A US owner found they sort of ran out of the box.
Now, he was a bit of a perfectionist, and for him the AFR and transitions were not good.
He shared with us the process of going from 'sort of' to 'properly', swapping this n changing that.
In the end he described the original purchase price as a 'down payment'.

Different matter if one has a rolling road and an experienced shop with all the parts.

Perhaps a quick n dirty dyno, is in order ? Bandit drive train = swing arm/wheel and 15" disk brake, aka, "brake dyno". NOT for 96 hp. pulls, but enough load to sort carb's ? Mount a beam type torque wrench, to read torque at the swing-arm. If and when, I find oem. injection, perhaps (2) 45's might feed that 6V71 supercharger on a RV8 build, I'm gathering together.

Put four rotors on that thing and it'll do the trick. Or maybe just one off a semi.

OR I could put 87 octane in that Bandit and really make it- diesel.....
