    Water fording ability

    Can anybody share experiences with fording water? Creek crossing ect. Also I have seen air box mods. Can anybody share how the mods have affected the water depth fording ability?

    Good mods, in the old thread. Subscribed, and good luck to the OP!

    I read it all. The vent also made sense. I had a king quad many years ago. I was riding at little Sahara and it died. Every time I would open the gas cap. It started for a moment then died. I finally found a kink in the vent hose! LOL anyway, I will pay attention to the area under the seat as I install my new rack. I will look at dialectic grease to prevent the water with minerals from shorting anything. I will also look at the plug wire in the future as well.

    The CV carb works on subtle pressure differentials that get adversely affected if tanks and carb vents do not constantly see ambient atmospheric pressure. This is why submerging the carb's vent will often have the bike stall within a few seconds, only to restart shortly afterwards once vent is out of the water. These pressure concerns are also why the air filter needs to not be wet, over oiled nor clogged by dirt.

    Thanks for that explanation Fred. I knew about the stalling, mine died the first time I splashed through a 3" puddle, but was fixed right up after I did the vent mod. Until you said that, I still couldn't really get my head around how plugging a fent would kill it almost immediately.

    I know, the water crossing stalling seems illogical at times.
    Some folks think the vent is sucking water into the carb and that that is what causes the flame-outs but I don't think so. I could well be wrong but it seems like the lines only start to draw a bit of vacuum before competing with the negative pressure at the manifold side of the carb that is responsible for pulling fuel through the jets and various circuitry and ultimately into the combustion chamber. No suck? Then no fuel. And that sucks.

    Just wheelie across the water and no vent mods necessary!

    Actually did that once, across Sespe Creek, but it was a 175cc 2 stroke.
    Would have been a serious problem if I lost it, as I was a long ways from home

    Is the Wyoming pic crossing Fontenelle creek between Labarge creek and Kemmerer? It sure looks like it?
