Carb vs. Fuel Injection

I have been looking at a stock 2002 Heritage, 2600 miles w/carb. My question is what are the pros and cons of FI and carb. Should I be looking for something a little newer w/FI? All opinions welcome.

MadCity is reading this now saying WTF is this?
I suggest you read through some of the threads discussing carbs and EFI in the Fuel Systems Forum.

Pro's and Con's to both. EFI can be fine tuned to a gnat's butt but it cost a lot of money to do it right. I just spent $800 doing that very thing. The carb is simple, direct, and almost anyone can rejet a carb with a few jets and a little patience.

Start up and warm up is brainless with EFI. With a carb you have to turn open the pet rooster and pull the choke knob and remember to push it back in before fouling the plugs. No biggie if you know your way around bikes at all.

EFI is in existence to appease the EPA otherwise the models besides the FLHT(C)(U)'s would still be carbed in my humble opinion. In my experience the EFI doesn't get much better gas milieage. A little maybe but not much.

Carb = Controlled fuel leak. Will never be accurate throughout the entire rev-range.

EFI = Computer controlled fuel delivery. Also programable. Will deliver more HPs by consistancy alone.

I have an 06 Deuce with EFI (which I was at pains to order specifically) and a PCB III. No real "problems" to date, but if I had to do it over, I'd get a carb. I do my own service, and could handle a carb but I wouldn't be able to handle an EFI problem. As I say, no problems so far, but I'm a carb fan.

Plenty of OPINIONS there. Doesn't hurt to ask for fresh opinions, does it?

As I am finding out, this EFI is turning out to be a pain in my a$$. I can't get it tuned right at all. I just started working with a guy that works with or at PC headquarters. I paid $600 to come and find this thing is still pinging. I'm not sure what the heck the prob is but the guy's that tuned it were new at tunning. So it was my fault to think it was as easy as plug and play. Hopefully with the help of the feller from dynoresearch it will be taken care of. Carbs have always been much easier to work with.

Nothing wrong with a carb. Especially if no major engine modifications have been made, and they're much easier to repair for a backyard mechanic or indy.

I have an FI bike, but wouldn't be a bit concerned about owning a carb. I wrenched for 4 years, and a properly setup carb rode just fine.

My bike has a carb. Many times I wish I had a FI.

Cold starts are fine, but after its been shut down a while it's always a guessing game...choke a little...choke all the way...no choke...

A person does get used to what the bike needs, but FI would seem to be goof proof.

The 02 has the Timken bearings, I would rather have them and a carb than not have them and have efi. If the price is right, there are aftermarket units that are said to be self programmable and that have wide band sensors.

I have both, carb & EFI, with race tuner (SERT). The ride with the carbed bike is more "relaxed" and less hurried, and also much smoother as far as surge & jerkiness at slow speeds. Also sounds better at idle. But ya gotta really let it warm up before it will run well, with the EFI it's "hit the starter & go". Both have their pros & cons. But if I had to sell one bike, I would keep the carb, mainly because of that smooth,relaxed loping ride.

carb vs efi

In the past year I've been lucky enough to own a carbed bike (my '96 Road King with an S&S Super E carb) and a 2006 Heritage with fuel injection. I took the Heritage in on a trade for a race car I was selling.

Was able to ride both bikes back to back during cold weather. A "pro" for the fuel injected bike was instant cold start up. No throttle twist, just turn the ignition on, wait for the pump to prime and hit the start button. A "con" on the fuel injected bike was that the idle never seemed "right" and always seemed to be too high, even after warming up to operating temp. Throttle response was good and ride was smooth.

On the carb bike cold weather start up is a little more involved, especially if it has been sitting a while. Even so all I have to do is pull the choke lever, twist the throttle a couple of times and hit the switch. Let it run for 15-30 seconds, push choke back in to close and go. Very rarely do I leave the driveway with the choke on. If the weather is above 50F then it's usually pull choke, 1 twist on throttle and hit the button. Hot start is usually simpy turn it on and hit the button.

Keep in mind, neither system (carb or FI) does away with the fact that you are running an air-cooled engine and that it needs to have some heat in it before you get even mildly aggressive on the throttle. *****My driveway is 1/4 mile from the main road so I have a little time for warm up before I have to accelerate thru all the gears*****


Nothing wrong with a carbed bike. On the same hand nothing wrong with an FI bike. I like both but tend to prefer a carbed unit due to costs related to performance upgrades and tuning ease/availability.

IMHO, you are not going to go wrong with puchasing the carbed 2002 Heritage.

Good luck with your decision and ride safe,
BK
