Hi there,

Is any one aware, if KTM's got any kind of water sensor fitted - that turn's the engine off while going thru deep water (up to the wheel level as on the photo bellow) ??



It happened to me twice. As long as nefr bars are covered with water engine turning it self off. Doesn't matter, if I keep the throttle - reps goes down along with the engine ...

Would appreciate any help.

I bet your carb vent lines are under water at that level.

Holly crap, that is insane unless it was an accident. I'm thinking you need a teryx with a snorkel. Mine must have cost alot more than his. I can't even imagine doing that to my bike or MYSELF for that matter. That looks COLD AS HELL.

Mate, Raptor 700 did it with no sweat at all !!

Chris, you reckon that vent lines would be the cause ? I could shorter them up or try to pull up upwards ?

mine are still in the stock location, i dont have my quad close to me to get pictures. but i'd think you should be able to re-route most or maybe cut them shorter.

i've been deeper then that, just make sure u keep that throttle pinned so you can get out..
Mate, believe me I was keeping my throttle up high. After few seconds engine was losing power and turned it self off. What's more, I didn't start on the first time (after puling it out side the water), I had to wait min 5-10min before the engine would start again.


XtremeSkier08 - are your carb vents lines in stock position ?

Are the wheels throwing water in the aribox somehow? I only sucked in a mist of water one time and it ran terrible. Drained the carb and it ran fine again.

On my Outllaw 2 of the vent lines are run up under the front plastics along side the gas tank, and the rest behind the motor. I left the float bowl line there and ran the other 2 vent lines up under the seat to keep them up high.

or maybe the fact that your running the quad through ice cold water. Almost any ATV will shut off when you run it through water that cold. Or possibly just seize up the engine. It would take no time flat for that water to cool off your engine enough to shut it off immediately. Our first race i ran the quad through a creek that was easily 18-24 inches deep and never had a problem, but it wasnt in frickin Antarctica, lol. Your NUTS

2 x Raptor 700 and 2x Can-am Renegate went thru - I mean just drove thru it ! Didn't even stop or choke water !

I still can't think of a reason why it would cut out on you. The carb vents ~ maybe. I'm not convinced that having them submerged would do this. If they were sucking water in possibly, but then there would be evidence when you drained the float bowl. ( by the wy have you checked that out ?!?) It does seem like that is as best a guess at the problem as can be made. My suggestion is get a BIG Thermos of really HOT coffee, reroute those drain lines, And go give her hell! HAHA good luck


Ohhh yes, I'll go for that B)

I might consider checking out carb vents, will let you guys know. Otherwise, If you got any ideas in regards of the above let me know. It seems that it happend to me only.

Just a thought but do you have an electrical fault being caused by the water? Maybe a plug that is loose or something.

It is the vent lines causing your problems. while it is running take a cup of water and stick your vent lines into it. your bike will shut off. There is a post on ktm talk about reworking the vent lines so that the bike will not shut off and keeps fuel from running onto a hot exhaust.
