I have fighting with a 07 WR450f that really hates puddles that hit the bottom of the frame. I thought it was electrical because some times it would just die like I hit the kill switch and other times it was more of a spit and sputter like I got water in the filter housing. I sealed up all the connections with rtv and doused them all with water in the drive way with the bike running. Worked great!! went for a ride hit a water hole and it died. So OK it must be going through the filter and not leaving any trace. I wrapped the filter w/tissue paper to see where the water was coming in and went and hit the hole again. It died. brought it home and hit it with the hose it ran fine while doing that. took it for a ride around the yard ran fine then I hit the puddle where I hosed it down and it spit and sputtered like there was water in the gas. I am stumped. Any help or thoughts?

If you mean riding through deep water that is up to the frame and not just splashing water, your solution is most likely this:


Take one of the carb vent hoses and re-route upwards over the battery into the airbox and this problem will disappear...

Common problem with these bikes. If all of the carb vent hoses are covered by water the motor shuts off and you get wet.

If you keep the throttle open when going through water, you will not suck it up the vent hoses.

So, my advice is to never shut off the throttle, ever.

PC1 still makes the carburetor vent filter kit, and a bunch of us use them in Baja to keep the Baja silt from finding it's way up into the carb. You could use this to route your vent lines higher so they never draw in water. Or just go down to the local hardware store and buy some "T" s and some tubing and make your own higher vent tubes.

I routed mine up behind the headlight/number plate. I haven't had a problem since.

The vent hoses already have Ts on them... just pick one off the branch and route it higher. Might need to extend the hose depending on where you route it but I have never had any problems routing the existing hose into the airbox.
