I have a nice ol' EVO 1340 Carberated Motor. I did put the S&S Carb kit on it and it runs great, never sputters and goes on demand.

My friend on anewer Ultra told me he would never have a carberated bike again and EFI is SO MUCH better?

WHY? What are the REAL differences....Pros/Cons? Thx.

 

I have had both. I like EFI better but would not sell an EVO/carb bike either as they are very rugged.

EFI is easier to maintain once tuned correctly, instant starting in all kinds of weather but require some expensive tuning to Stage 1 or better.

Carb..once you ditch the stock HD carb you are usually in business. You can tune it yourself easily. Negatives are damp weather changes affect carbs more than efi.

BUt I wouldn't trade a carbed bike just to get EFI if the bike was solid mechanically.

 

FI starts up immediately regardless of how long the bike's been sitting. That's what I like most about it. After sitting all winter it fires right up in the spring. Plus it's maintenance free. No forgetting to pull out the choke or push it back in. I don't miss my carb or choke.

 

The EFI is more responsive, the carb can be dialed in for far less cash and it's much easier to troubleshoot. there are no sensors controlling the flow just the right hand. Sure it might be a PIA on cold starts or long storage starts, but what are you looking for? I have both, and I am happy with them.

 

I like the carb cause it is easier to work on. I don't know about harleys but fuel pumps for injected cars are way more expensive than carburated ones. Plus, EFI is not actually maintenance free - it just takes longer to need maintenance. Often the cost is way more than finding another carb. Like was said below, I wouldn't ditch a good running carb's model just for EFI.

 

In my area I can go from -200 ft in Death Valley to a over 12,000 ft (Mt Whitney) in about an hour and a half. EFI makes life REAL easy for me.

 

Thats it exactly...EFI will constantly adjust fuel ratio to air....With a carb your stuck with whatever needle you've chosen....I like carbs, they're easy to work on, kinda old school. But lets face it carbs are going to be a thing of the past......believe it....

 

Any suggestions on aftermarket carbs? My 96 Roadking seems to be running lean around 70mph and it's hard starting.

 

Carburetors – A good tuner with get it right for that day; temperature, humidity, altitude, fuel. Change something and the carb can not compensate for the change.

Open loop EFI – Exhaust gas not monitored, other sensors monitor environmental changes and make small adjustments to compensate.

Closed loop EFI – Exhaust gases are monitored for air fuel ratio adjustments are made within system constraints to keep the air fuel ratio as some predefined ratio (lean)

My 2000 sportster has a carb. I did the initial tuning and then had it dyno tuned. I was pretty close.
My 07 RG is fuel injected. Carbs are tuned
The only real difference is that I can feel the power loss when I’m on the Sportster in the mountains. The RG feels like it pulls the same where ever I am.

 

Closed loop systems don't allways have to be lean....Fuel managment systems work great.......
