    Friend did it. Said it was a PITA and he'd never do it again. Way easy to just buy an 08-09 and just swap your accessories over.

    Yea I’d imagine it would be a pretty major undertaking!

    I swapped my 2006 990s fuel injection for carbs from a 2003 950. It's only a pain in the ass if you are in a hurry to get it done, I was in no hurry and thought it was a fun and interesting project. I swapped wiring harnesses.

    It’s really not that hard. It took a few trips to eBay & the dealer as I realized which sensors I needed, and I ended up just buying a 990 left tank & fuel pump. I did already have a 990 timing ring around so I’m not sure if those are hard to find. I expect it’s still a dealer part or you could pick one up from someone doing an fcr conversion.

    I own an 06 950 "S" model and a 13 990. The 950 is smoother and "feels like" it has more torque in the mid range.

    This is not the usual case, I think it's just that the 950 is jetted correctly and the 990 is not.
    By 'smooth' I assume you mean vibrations? The 950 with carbs has better throttle response from the factory.

    No, that's not what I mean.

    The throttle response is smoother. This is a common comment about the 990 vs 950, as well as a general theme of mature carb'd bikes vs. usually "First Generation" EFI bikes (often described as jerky throttle response; the same exact feedback applied to the Gen4 vs. Gen5 VFR in the 90's). There are threads on here going back to 2006 that talk about the same issue. https://www.google.com/search?clien...dvrider.com+ktm+990+jerky+throttle+950+smooth

    Both bikes are jetted right. The 950 is tuned very well, and the 990 has a full Rottweiler system with closed-loop PCV to optimize for correct AFR.

    This is not a comment knocking EFI in general or to indicate that I have a problem with EFI. My 500 XCW, Ducati, and 1290 SAR all have fuel injection and throttle response that is very smooth. The 500 is dead spot on.

    In the 990 vs 950 case, one net result is that the 950 is easier to ride off road. But you do have the hassle of a carb.

    I thought about doing this as well, rear carburetor is upside down and runs out of fuel on extended long wheelies, a big drag! Floats bounce too much in woops causing loading up also.
