And Now for Something Completely Different: Twin-Cam Efi to Carb Swap and "Chop"
Been working on this bike for the last year or so while riding it, but this winter I decided to go bigger. It started life as a '10 Crossbones. This is what it looked like at the end of last riding season:
Sporty tank, bobbed rear fender, forward controls, relocated switches, all sorts of little things. I also put a dyna 150 wheel and tire on the bike and got rid of the huge 200 tire it came with. Nothing too drastic but combined it all sort of slimmed the bike down.
Well this winter the BCM went out. 350 bucks for the part plus whatever Harley charges to reprogram the thing to work with the alarm and the ECU. **** that I said, I'm going carbureted. It's a 96" twin cam motor, so I have to get a little creative because the 96" motors never came carbed from the MoCo.
That's the entire wiring harness, minus the main power cable for the starter, and the two voltage regulator wires which I'm reusing.
Throttle body out:
Parts are in! Some of them, anyway:
I was lucky to find a used but never installed Super E carb and Evo intake for a good price. I just need to seal up the vacuum hole on the intake.
Carb install:
Had to shave down the intake a little bit, it was 1/8" too wide to fit between the cylinders.
I'm mounting one switch on the handlebars, a factory XS650 switch. I'll use it for high/low beams, turn signals and horn. The kill / start / ignition will be somewhere down by the seat.
EFI wiring before:
Now, she's naked!

Thanks guys, it's coming together slowly. Should be doing more wiring tomorrow, I'll post an update. Actually got the blinkers and headlight all wired up today, next would be the ignition but I'm waiting on the module before I figure out where to mount everything.
It's a 3.3 gallon nightster tank, but with a petcock instead of a fuel pump. I believe some sportster models came with these carbed tanks, but if you have fuel injection a stock nightster tank is identical. I got this one off Ebay.
