There have been a few of us who have done our 01 SERG's. Had I known it was so easy I would have done mine sooner. I have zero regrets and love the carb over the injection.
Start with the parts manual form your year bike, 04?
Wiring, You'll need the Ignition patch harness from a carb bike from your model year. $51.29
Intake, which ever one matches your carb of choice and motor size. $48.00
Carb, I ran a Mikuni with a Riverra cruise control adapter, the CV is a fine choice for the cruise. $75.00
Ignition, I went with a Screamin Eagle box and coil for my year bike. $93.00
Fuel tank, petcock conversion kit with a 22MM petcock (link below for the adapters). $47.28
Misc, in line fuel filter, map sensor clip and screw. $1.76
I spent $317.23 on my conversion as I already owned the carb and petcock. It took me less than an afternoon to complete and everything was plug and play, no cutting. I sold the injection stuff along with the ECM for almost what I paid for the conversion parts.
You will also need an air cleaner assembly. I ran the Mikuni round one initially before switching to a Cycle Visions Mo-Flo.
