#6From the amount I read on here, and the KTM forum it's clear that EFI takes a while to get right, and that KTM are not the first to suffer teething problems.
It's hardly a disaster though and most riders are happy.
FWIW The RC8 I rode had faultless fuelling at all speeds, but then I do own (and am used to) my Superduke. Having said that the RC8 is NOT a town bike for plenty of other reasons than fuelling.
Anyway, I'll have a read and add this one guy's opinion (cos that's what it is) to the mix.

#12What some people are losing sight of is what the Superduke was built for. It wasn't built as a commuter. Now Im not saying it can't or thet you shouldn't, but it's in this kind of riding that the fueling rears it's ugly head. Now, put it down a set of twisties, hang off like a loon, stretching the cable at every oppertunity and the fueling is spot on. Would you slag off a race horse because it couldn't pull a plough like a shire horse? No, because it wasn't bred to do that job even though it's still a horse. So please don't slag off the SD when you're trying to make it do stuff it wasn't designed to do, if you are trying to, then you have to make a few consesions and put up with less than perfect fueling. If you're still unhappy, you could always buy a *onda .

#18I have come to the conclucion , that guys who come off inline fours onto the SD get rateld with it ,becose it isent eney thing smooth abowt it low down ,
this is a bike that needs to be riden 'not poodeld arownd on ,
there are riders ,and there are mobile chickians normaley rideing inline fours .

#19As I have said in other posts, we all need to write/e-mail KTM and push this issue regarding the fueling and possible ECU Keihin fuel cut of programme back to KTM, and keep pushing, eventually they will have to respond if we make it a big enough issue, mikef4uk has the right stance back to the dealer, and keep on going back, till they a blood sick of us, we are not asking for special treatment here, just a bike that runs half decent (I am not asking for in line four smoothness), we have spent good money and deserve better than this bad fueling, be it down to the throttle design, ECU or fuel map,

#28I dont know if the mapping on the 08 SD-R is any different than the regular SD but i have not had any prob with mine. or non worth all the BITCHING on this page. nothing done, bone stock with 1000km on it. she maybe a little bit of a twitchy bitch around 3800 - 4200 rpm but come on man you have gears to chose from. why drive it in that rpm range? it pulls beautifully through there in just doesnt like to sit there.

#34(Threads should never be deleted cos they are not positive IMO.)
But...
The debate does seem to be getting a bit out of synch with most people's actual experience. I have no real complaint about teh Duke's fuelling, and what snatchiness there is seems to be down to the engine configuration more than EFI, and to me is more than acceptable for 99% of my riding (consider that I commute through Central London every day).
Before my 07 Duke I had a KTM 950 SM - with carbs.
As a big V-twin it was pretty lumpy at the bottom end, and required a fair amount of clutch slip for smooth running below 4000 rpm.
When I was buying, I did try the SM back to back with a 2006 SD and preferred the slightly smoother carb'd engine, but not by that much, however, when I test rode an 07 Superduke I thought the fuelling was even better than the SM. I rode a stock bike, and one with Akras and PCIII. Both were fine, even in town.
...
KTM LC8s are big lumy V-twins and need some smooth clutching at low revs, but overall it's the best engine of any bike I've owned (19 at the last count). If I wanted a super-smooth (bland) power delivery I'd buy a Honda in-line 4.
The only small "issue" I suffered with EFI was getting low idle speed (unadjustable) and stalling in town as a result. This was cured by riding a bit harder, which the SD seems to thrive on and inexplicably upped the idle speed. ...however, I do wish you could dial up the idle speed manually.
