Yes, the EFI sporty is much better than the carb model. More horsepower right out of the box, no warm- up, no surging/ stalling and better fuel economy, as well. My 2007 1200c is better in every way than my 2005 was.
It's already faster than any other harley save for the water- cooled ones. Put the SE street performance pipes on and you don't even need a re- map if you keep the stock intake.
Now it's faster than most heavily modified big twins. what's the downside?

Is this a serious post?
If so, well, everyone is entitled to their own opinion.

man i don't understand some of the comments against efi. makes no sense. with efi you get far better tuning of fuel delivery... if you know how. granted, the cost of getting into the ecu is prohibitive, but thats the point. there are too many people who just don't understand fuel delivery.

Everybody has their own opinion. My friend loaned me a 1200C EFI and it coughed between shifts all day. My carbed S (set up by me) runs better, hot or cold. Sporties are set very lean at the factory to reduce emissions. Improve the breathing with intake and exhaust, richen the carb, and they run quite well. With very little stumble once setup correctly. Might not be the fastest scooter, but...

(EFI vs Carb'd debate)I think some EFI people are smoking too much crack. Well, even some carb'd guys are probably smoking to much too. However, I do agree with some of you guys on the EFI can be a simple plug & play set with downloads.......but a tuned carb works just the same for a LOT less $$$$. My CV carb is adjusted so that I don't have to keep fiddling with the choke upon start up/warm up due to a properly adjusted tension nut on the choke. My bike doesn't pop, cough, or backfire while idling during warm up, and I can take off right after a cold start & find my choke sliding back in on it's own just a few miles down the road. It all depends on how each bike is set up. No, EFI does not eliminate the cold blooded nature of the engine.....As a matter of fact I hear a LOT of you EFI guys saying that your scoots stumble and/or die during warm up. All I can say is my carb'd sporty doesn't do that & I'll stick with my carb. Done with my

EFI mainly came about because of EPA regulations, and to prevent anyone with a little mechanical ability to easily adjust their fuel intake to the correct A/F ratio.
EFI systems are usually set very lean at the factory to meet EPA standards, and 99% of owners just leave them the way they are, running lean and running hot..
EPA doesn't stand for Enhanced Performance Application.

sorry but epa jumped on efi because it locked a lot of people out of tweaking fueling. efi has always been a better way of doing things.
remember there are lots of people who aren't mechanics and own screwdrivers. every used bike i ever bought had carb problems because people just don't know what they're doing and they refuse to admit it.
efi is better. if you want a good explanation of why, google ecmspy and download the tuning documents. once you understand you'll change your tune. carbs just can't do what efi can do.

EFI is a great idea on paper, but doesn't ride as well in real life. It's been perfected in cars but in bikes it's still a bit crude.
