I have a rancher that has a custom snorkel and also has the differentials vented. I twas done by the previous owner and he had left it sitting. 06 with 59 hours! I took it in for the first time to have my carb cleaned and tuned since it didn't want to drive until warmed up. When I picked it up the mechanic asked me who did the venting. I asked if it was wrong. He said no but they forgot to vent the carb. So my question is how important is the carb being vented when driving through water? I hope this is not a dumb question but I don't want to pay them to vent it if it isn't really necessary. If it is I will have them do it. (staying dry until I know):wink:

Also if I get an aftermarket air filter could that mean I need to adjust air/fuel mixture? Thinking about a UNI.

Thanks!

If you are going to be going through deep mud and water, everything needs to be vented up high.

Please add some spaces so the forums don't get stretched out so far.:r_c:

As for the venting, if you're going to keep it all like that, then I would put a 180 in those differential vent tubes so they don't get water down in them.

The other one might be the carb overflow, but the carb has a vent line, also. You could probably do this yourself. just pull the vent hose off the carb and go buy you a long piece of hose the same diameter and run it up to the top of the frame and along beside those other three hoses.

By the way, that's a nice 4-wheeler.

What kind of riding do you do? Unless your riding in water and mud over the top of the tires, you may not even need the vents.

Thanks for the comment. I will try to find the vent that is already on the carb if I can Like you said it should be pretty easy.

I am in FL so it is impossible to stay dry sometimes because getting to a new area sometimes means crossing a ditch, canal, or driving through a culvert. It has gone well above the tires at times.

Trail riding is fine for me but I just don't want to come to the situation where my ride has to end because of a water obstacle and if I cross I also don't want to damage my carb with any water.

Yeah, if you will be in deep water, then it needs vented.

yeah just run the vent lines form their exsisting spot below the handle bars and run them up the snorkel to the otehrs also if i were you id cut that partial ptrap on the top of the pipe and just use a long sweep 90, with it the way it is the atv has to work harder to breathe than it would if air was going directly into it, and also if you ever do get in water that is close to it could suck water into the snorkle.ill take some pics of mine and post em up.

Here are some pics of mine, im still debating on how i want to vent mine right now they are still in stock spot im thinking of self tapping into my snorkle i have now and threading a barbed fitting into pvc pipe and hooking hose to the barb, which will allow all my vent lines to breather through the snorkle and i dont have to worry bout them being under water at all.
