Yes, thanks Seth, and good job! I want to try akra remap for my 690e w/ LV pipe. Got to get my dealer to beg, borrow, or steal a KTM diag. machine. He doesn't want to buy one. I have the only FI KTM they ever sold.

So, if you don't mind, feed us any info. on EFI and mapping. This stuff is a mistery to us old carb. and jets guys.
yeah, the old DIA was 800 bux i think new. ktm is offereing a $750 buyback on the old unit to ofset the $2250 pricetag on the new superfancy hoitytoity fangled new one. The old DIA tool is particularly user un-friendly, i hope the new one is a bit better.

I'm not a big FI guy, give me a flatslide anyday. I get to work on these things everyday. so i might pick up a thing or two from time to time (only when my brain cooperates).

Armadillo - nothing to do with exhaust, but my bike broke down riding across America in Texas. It turns over great but wont start, like there is no gas. It is throwing the 41 code "check fuel pump control".

The dealer doesn't have the diagnostic tool and I don't know of one around here who does. Is that something that would identify that problem?

Doing this is like blinding throwing a bigger jet in your carb. It may work but the odds are much better that the bike will run like crap and little or no performance gain will be realized. You have to be careful swapping components around in an EFI system because if you put an aftermarket injector in there and the resistance is wrong you risk letting the smoke out of your computer.

I would bet that the stock system has a pretty good range of tuneability before you need to start changing out components. I mean my bike makes plenty of power with the stock settings and even the stock exhaust. My only complaint with the stock exhaust is the heat from the cat converter.


If you start changing your cams, engine displacement, exhaust, ignition etc then you might need to go to a different injector size but I don't know of many people who will be doing this.

I notified LV about the reports some have had with power loss and that some had had good gains. LV is willing to get a bike dynoed to see what's happening with the mapping and get it sorted out, anyone in the SF bay area that has an SBK on their 690 and is willing to give up their bike for a day please contact me. I only need one bike and unfortunately my bike won't cut it because I'm running an X3 not an SBK.

We'll post results when done..

+1 Seth.

I ride mine with the stock exhaust, with the ignition map on the standard setting. The bike runs great. It is a little soft on bottom, but this motor is not a lowend torque machine. The soft bottom may actaually be a plus in tight technical stuff, not too much hit. I ride some pretty tight trails and have not even bothered to gear down, I don't feel it is needed. I think I would run out of turning radius way before I run out of low gears.

I am waiting on an FMF, due to price mostly. I just want to lose the weight and heat as well. If FMF fails to deliver I may look into the Wings. It is a sexy piece of harware for sure.

James, I'm still willing to loan my 690E to LV for testing. Also, a recent Akra re-map plus some tweaking seems to have stopped the stalling. Email me for more details.

Can do if someone can loan/give me an LV.

Only if you change your name over to KTM newbie
Actually I got a few responses so we should be good to go, thanks for the sacrificial offer..

Wings pipe is superb. No remap necessary. Bike runs at same temps as with stocker.

Well, got my bike back from SMS Racing. Put the LV can on last night did the battery disconnect and let it idle for 15 minutes. This morning I went for a 100 mile ride. Mostly pavement a little off road. About half the pavement was city riding with a bit of stop and go stuff. My seat of the pants dyno tells me it has more power down low. It does 3rd gear roll on wheelies with ease even with my fat arse on her. Hardly any heat coming off the can which is the main reason I bought the thing so I have to say I'm very happy in that department. It's louder then the stocker, but it's not any louder then my 450 EXC with the stock de-restricted pipe. It's considerably lighter then the stocker. I like the fact that the LV emblem isn't stuck on. I prefer the clean look of no logo on it so I'm leaving that off. I did have it stall on me once as I was pulling into my driveway. Gonna do another couple hundred miles this afternoon. Should have a good feel for it by then. So far though I have to say I'm really happy with it.

Used to have the SBK with the Akro map

Pro's: Better power everywhere, bike ran smoother (less vibration), cooler running, noticeable weight difference.

Con's: Too loud

I'm back to the stock pipe with the stock map - I just cannot live with a pipe that loud.

P.S. Anyone want a pipe PM me: $250.00

I modded my 2008 690 Enduro with the Leo Vince SBK pipe to cut down the sound output by 50-60% and eliminate the low end transition stalling problems. Works great now.




The OEM can was just wayyyyy wayyyy wayyy TOO HOT.

Here is a link to the successful $0.99 mod:

Put a couple hundred more miles on it and have had it stall on me a hlaf dozen times. Gonna try SkyPups mod and see if that cures it. If not, then I'll go get the Akro map.
