Question about sons bike stalling

Saturday my sons 2012 KLX140L just died while going slowly through a water "puddle" approx 1' deep. The water was up around the crank case but nowhere near the carb or intake box. Then it wouldn't start. After pushing it out I was able to start it by full choke and full throttle. After a few minutes it would idle only on full choke. A few minutes later it idled and ran fine; luckily as we were at least 8 miles from the truck. It ran great the rest of the morning. Once home I checked it all out and everything looks great. No sign of water in the oil. Air box was clean as could be. I'm stumped and don't want it to happen again with worse results. Any ideas what might have caused this?

tough to say for sure...but clearly something got wet. When it dried out, everything was back to normal. I would not worry about it...unless you/he make/s a habit of going through deep water. The water and the running condition were almost certainly linked.

no idea if this is true for the klx140 but with my klx250, the carb breather tubes hang low on the bike. Deep water will cause the bike to stall out. Many KLX250 owners (including me) have done the breather tube mod (install a 'T' and run a tube up high along the frame). Hope this helps.

p.s. I hope the new owner of your Tiger is treating her right!

+1 on the vent tube. My KLR 250 did the same thing, The T vent mod will allow the bike to restart easier after a fall also. emti

or just pull the vent line off all together. it's there so when you dump the bike it don't spew fuel on your balls.... not a problem as long as the bike isn't upside down on top of you

Thanks, I will look into that as I think you are onto something.

I haven't heard from the new owner so I assume all is well. He seemed quite happy riding off.

Well actually one time last year on a steep sandy down hill he fell over and ended up slowly sliding down the hill with the bike above him on his leg; picture me behind him looking at the under side of the bike as he slid. He was laughing so hard and with all his gear and water pack weighing him down he couldn't get out from under it. When he moved he would just slide more. We still laugh about that one. That would have been worth the price of a go pro just to film it and watch some day when I can't ride anymore.
