You guys are making it sound difficult. Its not. First but the conversion kit for gas tank that eliminates pump and the two fuel lines. Then throw away efi intake and all its components. Slap on a s&s carb and intake then throw away that ignition brain box it has and any efi wiring.
Put a dynatek or twin tech ignition in the nose cone of bike. Run the 4-5 wires and its down the road. No need to worry about getting complex on the wire harness

Awesome man thanks...after 15 years I finally found the courage to fix my bike and its all thanks to you. I don't know what you do for a living but idle it's not a motivational speaker then you missed your true calling.

OP.. you go right ahead. Forget the ney sayers.
Here’s the math.. dude with fuel injection or throttle body spends $500 with a tuner.. he has to make an appointment.. possibly drive 2-6 hours to this tuner.. is he a good one? He has to wait on him.. and once done he can’t make any changes..
OR
He grabs his bean can filled with jets and make the adjustments right there
They both make the same power.. but you decide.

You can crudely tune fuel injection to the low level of a carb. Dyno is for people who want more. People dyno cabs too.
Go get canned generic map, no worse than choosing between a couple different jets, needle, and half turn of a screw.
Yes carbs are easy, cause you don't have a lot of options .
I think silly to rip out Delphi. But people used to do it. MM now a days I might rip out

I have wondered why you can't buy carb, bung hole converter, petcock, cables,and ignition, abandoning fuel injection in place. Not saying that is all inclusive parts list.
But I am sure more to it. You can probably find 20 year old threads with parts listed . I suspect it adds up.
Probably easier to figure out on pre 2007 bikes, follow manual to some degree.

I know a mechanic who has turned down this job. I suspect the non wrenching hours add up to more than customer wants to pay

If I had a MM Harley and had problems I would look seriously at an S&S carb conversion.
