So I can now confirm that when this stall and no-start business occurs, the pump is NOT priming the system as when everything is fine.

Does this help or sound familiar??? Please...my dealer is awe-struck and lost...
Sounds like either the pump is dying or some upstream electrical issue so no juice getting to the pump. Are all the other electrical systems working (that you can check) when this happens?

Everything else works with no apparent issues. It's really strange - I rode 40 minutes at 130 kph on the highway today without a single glitch and then literally as soon as I exited the highway and hit the red light at the off ramp, it stalled and I had to wait nearly ten minutes before it started again. On the way home, same thing - flawless performance on the highway and then as soon as I was in stop and go traffic, it started stalling and not starting again. This leads me to believe that there may be a power starvation issue at idle (or near idle at low revs) - perhaps exacerbated by the current draw of the rad fan. I am going to unplug the stator tonight and measure its output to see if I can rule that out. Does anyone know how to measure and determine the health of a stator?

If I had any hair, I would pull it all out...

so you think its a electrical problem of low voltage at low rpm.........right?
but only after it gets hot................. right
you think it may be the stator is not putting out enough voltage/current at idle............? right

check the reg rectifier when hot.....that is the time you will notice beginning stages of rr failure


truth is there are many things that can go wrong with a fi bike that have similar symptoms
the more you can narrow it down the better you can trouble shoot it without as some have put it "throwing parts at it

i have had symptoms similar to yours with:
fuel pump beginning to fail
fuel pump hose knotted from the pump coming out of the holder
dirty injector
fouled plug (how do you foul a plug on a fi bike?? wtf)
cracked plug cap and doggy wire
master starter relay
low battery
good luck

With what little mechanical knowledge I have, I sort of believe it is electrical related - also somehow related to heat. Again, 40 minutes at 130kph on the highway without missing a single beat (assuming the rad fan never ran during that run) and then as soon as I get off the highway for a red light, bam!

I will figure out how to check the stator and regulator rectifier but you're right in saying that it will need to get right up to high temps when I do test them...somehow...

I ran a multimeter on it just now. Over 14 volts at rest, hardly any change when I turn the ignition on, no drop below 12.6 volts when cranking, running steady at 14.x volts when idling and higher RPMs. I let the bike run for 20 minutes at idle, letting it get good and hot and measured voltage - no change. I turned the bike off, good high voltage over 14V, cranked and started it again, no issues. I'm guessing my battery and stator / regulator rectifier are doing their job as designed.

Incidentally, the bike did not stall or not-start this time despite getting hot, etc.

I'm losing my mind...

With no fault indicators on your dash panel, it would seem to rule out a bad IAT or air pressure sensor....
try setting the map switch under the seat to the full power setting and see if that helps..
If the fuel pump is intermittent, either try a new pump or start looking for wiring problems.
One of my riding group had his 690 go completely dead which turned out to be several wires grouped together that had rubbed off the insulation
until they shorted...

I'm don't own a KTM..but that won't stop me from giving advice
Have you tried taking off the fuel cap when it stalls to see if it might ba built up vacuum problem?
Could be a needed vent hose is pinched somewhere.

I have a friend who had kinda the same sort of thing happen. It turned out it is the TPS is starting to go. They re-installed the map and seems to be working fine for now. There is no way unless you hook it up to see if it is wrong.

I finally caved and brought it to my dealer. The four codes that he was able to read were all voltage related. THAD and other settings are spot-on. He's throwing in a new battery and reloading the ECU map. He is confident that all my described symtoms match the causes. We'll see..he did also confirm that KTM has acknowledged a fuel pump issue and if he had one in stock, he would swap it. I'll have to take it home as is with the new battery and map-load to see what happens.

Holy Shit.

I predict time will stop tomorrow....

Sorry about your running issues. It's no fun....

My response about fixes will be something very similar to Bob's so, I'll refrain.

Hey, guess what...same F*#KING problem still. I called my dealer who said "oh, it may be the fuel pump afterall - please bring it back to us so we can pressure test the pump. By the way, the pump is $428 and is on back-order for the next three weeks" I said "if KTM has acknowledged it as a known issue, ask them to give me a new pump" and he told me that the claim process could easily take 6 weeks but either way, they need to diagnose it again.
I suppose that if I need a pump, I should just get the cacycleworks.com pump for $129 instead, right?

I didn't read all posts.

Did the dealer load both maps then do the 15 min on a dead cold engine? Try the throttle reset and idle again.


After new tips on my bike it did the exact same thing you describe. Slightly different bikes but stinks of the same prob. After the dealer loaded two "KTM" maps from KTMs website my bike ran perfect until the tank hose kinked. That hose gave me once a day stall problems for a few days until I spotted it.

I've also ordered a fuel pump from CACycleworks just in case...

I didn't have the stalling issues with mine. Just the pump not priming therefore the bike not starting. Replaced with the ca cycleworks pump and so far so good. I'll have to ride it for a good week or so to make sure though.
