Sputtering When Wet - Breather hose?
Posted August 21, 2005 - 01:32 PM
I was running the washes here in Arizona (Had some 4-5th gear @full throttle runs in 4-8" deep water) and the 03 WR450 started to miss fire, thought this might be a fluke, but changed the oil just in case it was the crank case breather tube taking a drink, oil looked fine. Next week, same problem. I have now re-routed the hose to point to the rear exiting at the bottom of the rear shock. Not sure that will help, but seems to be a better place for the hose anyway. I am looking for a check valve to see if that will help. I also resealed the ignition wiring side case rubber plug.
Question is, has any had a similar problem? Could this be water in the wiring?
Thanks in advance for any help.

Your carb vent tubes are sucking water.

As always you should search the site before asking questions. This seems to be a common problem (I didn't notice this problem on my 98 WR400, even after about 4k miles).
Most everyone is piping straight to the airbox, but I am concerned about the oil buildup. The T-Vent sounds good, I will resreach that one.
