I think the cost would far out weigh any benefit, and the only benefit I can think of is the carb is a much simpler technology, if I'm wrong or missing something please enlighten me.

This question Always gets no answers, and Tons of why would you want to do this questions.

Why you want to do this is NOT the question. How, or is it possible, IS.

I would LOVE to convert my '12 to a carb. I converted my '05 from EFI to carb and it never ran better, ran cooler, and got significantly better mileage. Not even a single bit of regret and it was extremely easy and cost less than $500.

That said, this is what you have to think about, vs justifying why YOU want to have a carb...

Converting a newer bike will be next to impossible without a huge amount of work and outlay of cash. Here are points to think about:

- No carb specific sub-harness for newer bikes. In the past when carbs and efi bikes existed you could purchase the carb specific sub-harness for abou $100 and just unplug the efi harness and replace with the carb/ignition harness.

- no aftermarket electronic ignition module for late model EFI only harness. No carb harness nor carb'd touring model past 2007 I believe, which means no aftermarket electronic ignition module. You can't use the EFI ECM without EFI crap for ignition only.

- You'd need to build your own dedicated wiring harness (wouldn't be hard) from an earlier model so you could go with an ignition module from an earlier bike. Or complete custom harness to power an aftermarket ignition. Real race bikes exist and are built every day which use state of the art ignition systems and carb....

- speedo and tach from an earlier bike might be required as they are part of the carb sub harness (speed pickup off trans).

- You're going to lose your cruise control. Period.

- Near as I can tell you can still use the same adapter used on the 5gallon tanks which allow Harley to use same tank for efi or carb bikes. It'll allow you to install a petcock.

- You'll also lose the ACR's if you have them.

- Carb mounting would be easy using an air cleaner assembly from earlier bike because the dimensions for all the bracketry is the same.

- you'll need a different switch housing to allow using carb cables...

- IF you do the conversion, nobody but someone like-minded as you (or me) will buy the bike from you as is. You'd have to convert it back to EFI.

Simplicity, flexibility. Fewer sensors to fail, dump the TBW garbage, no need to get your bike dyno tuned for $300+ minimum everytime you make a change of signiicance... Cooler running engine, better fuel mileage than the earlier non-O2 sensor EFI bikes.

Downsides exist of course. EFI is a bit better behaved when conditions change, ie altitude. nice cruise control integration. Current HD EFI is almost as smooth running as a carb and even the fuel mileage has improved with the use of the closed loop, assuming you're tuned to run in closed loop.

Sadly I agree that at this point cost does out weigh benefit. The other thing to think about is whether emissions testing will come to your state... No way you'd be able to pass a 'smog' test with a titled EFI vehicle equipped with a carb, visually and certainly not from an emissions stand point.

Of course these are just my opinions and based on my experience converting my '05. I converted it back to EFI when I traded it in btw... and have all the goodies waiting if I ever decide to pick up an earlier bike.

Just a quick apology in advance cuz I'm fairly certain I may have come across like a complete a-hole... It was a knee jerk reaction based on every other thread started on this subject.

Get rid of the rev performance fuel system. The EFI has to many advantages over the carburetors too swap it out. Your EFI is controlled through the ECM so there is no need to re-jet. Once the correct map is in the ECM the ECM will make all the adjustments to the EFI that are necessary for the bike to run right, this is important when it come to elevation changes when riding. If the carbs were still a good option for these bikes I would think HD would still give the customer the option of what they preferred. Why don't you look into a good auto tuner like a Thundermax or Power Vision.
