Carb vs Fuel injected

im guessing the fuel injected ones 2003-2007 are better than the 99-2002 models.. but i could be wrong

are there any performance differences between the two?

im guessing the fuel injected ones.. go faster and... have better fuel economy

im still a newb with motorcycles

I may be wrong here but, injected models have slight performance increases over the carbed models and fuel effiency is up. EFI has been replacing carbs to help meet new emissions laws. Carbs however usally have alot smoother fueling and don't rely on a box of electrics to make them work (just another thing to go wrong.

Cheers.

no substantial difference in performance stock

carbed models are easier to tweak substantial HP gains

the only reason poorly implemented EFI is jerky is because of emissions regs, you could program the black box to provide exactly the same fuelling as carbs but then you'd have the same emissions problems that carbs have (not to mention slaughtering any catalytic converter you have fitted). they can also ice up, they can never be as precise at fuelling as EFI so less mpg, poor hot starts in hot weather because the fuel boils, and the venturi effect required to draw fuel reduces the max power as it restricts airflow.

that said, carbs will be lighter, cheaper and easier to understand than the complex mass of wires in and EFI box, but i reckon EFI gets a bad reputation not because of any inherent problems, but simply because it's usually badly implemented, giving an easier job during emissions testing, but giving the rider a hard time.

perhaps this is one of those "old school / new skool" things

THe FI on the SV is flawless Ride a honda if you think otherwise

The performance differences are from the cams though, not the FI, and those are retrofittable. Some say a carbed model engine with all stock induction but the injected model cams makes more power than the FI, who knows really...

The FI's perfectly good at its job, but it's also pretty basic, no meaningful adjustment- that gives away the big riding advantage of FI IMO. The carb setup on the SV is equally basic and also pretty good, so when both are working well there's not an awful lot between them. More FI users seem to have problems with adjustment though, maybe because more of the FI is set up badly, not sure. I like carbs, personally, because they're easier to mess with but if you're not going to be mucking about with it then they're much of a muchness. Fuel economy's very hard to compare, because it's so much down to how you ride it, user reports are pretty useless for that.

The FI models are harder to access the clutch, because they use a one-piece side panel- you need to drain the coolant and remove the whole panel, with the carb models you can just remove the clutch cover. OTOH, they quite often develop leaks.

Go for carbs, they're simpler.

(and need I mention that curvys look much better)

And northwind (Andy?) while you're here...

After putting a Fuel SS oval can on I seem to have a flat spot at about 4500rpm, shows itself as a hesitation when accelerating at WOT.

I'm thinking shim the needles a bit?

I have recently changed from a curvy to a pointy. And to be perfectly honest, if you are simply looking at it from a riding point of view without all the technical stuff I would say the pointy injected one is much the better, plus the fact of the adjustable fromt suspension. You need to look at the bikes as a complete package not just carbs vs injection. And the pointy blue ones are the fastest!

K2s have that as well, and it's retrofittable... Not that it's worth retrofitting for such basic adjustment, it's only preload.
