Hi y'all I'm new to the forum! Hope I get to know a lot of y'all. I have a 2004 big bear 400 2x4. Me and my buddy are getting more and more into mud riding behind his house. And that means the waters getting deeper. I want to put a snorkel on my bike and tires. Some people tell me not to because ill have problems and another's tell me to. I really want to because I'm always nervous about getting water in the pipe. I'm only 16 and I don't know to much about the engine and all that. People tell me ill have to mess around with the jets. I don't how to do that. I'm putting tires and rims on my bike no matter what. I'm getting the Maxxis Mudzilla 25x8-12 in front and 25x10-11 on back. Should I got bigger tires or stay with 25. Anyone on here has those tires? Are they good. Would like to get as much info. But the number one question is with the snorkel. Thanks!

 

I don't know about a big bear, but i have seen some snorkels work just fine without any jetting and some that didn't. The key is to make the snorkel as straight as possible without too many bends. I snorkeled my rzr and it's the best mod that i have done - no more worry of wet belts! It's been across a 4 foot deep pond at Busco Beach with no problems! Mine worked just fine with no other mods but it's fuel injected.

some people may say - "well, you'll never sell it with a snorkel because people will think it's been swamped". Whoopdy-do. Well that may be true and turn away some buyers, but I would rather buy a atv that has been swamped with a snorkel than one that has been swamped without a snorkel, aren't atv's made to be swamped and isn"t that what most people do with them anyway? If you get water in the air intake it will make for a bad day.

If that's the type of riding that you want to do, I say go for it and if it needs rejetting all you have to do is ask and someone here will help with that, too.

 

Thanks man! Anyone else got any tips or suggestions?

 

hi Cajunmud.i really have nothing to say about your post.i just want to fallow this thread.i also have a Big Bear 400 but it's a 2003 and a 4x4 . like you i'm new here and try to learn as much about the Big Bear as i can.
i like what Raptor 450 said.

 

Nice to meet ya. I also liked what he said to. I love my big bear it tough and went through a lot of stuff for me. I got it when I was 8 or 9 for Christmas and now I'm 16. I'm never letting it go or unless I need to.

 

Are you talking about snorkling the exhaust only? I would snorkle the air box first. I am pretty sure the 400 big bear does not have a CVT transmission so you would be good there, correct me if I am wrong. For the exhaust as long as the engine is running you will not get water in it.

I wouldn't go any bigger on the tires. Mudzilla's are good but heavy tires and anything bigger the 400 is going to have a hard time turning. Also, check for vent lines for the engine and the transmission, you may need to extend those up as well.

 

just wondering, but is the 2wd gonna hinder you from making it thru deeper holes anyways?

 

I have seen some little 250 ozarks and ranchers go through some pretty amazing holes before with the right tires.

 

yeah thats true...i just didnt know how his 2wd would do in deep or thick mud. cause if it wouldnt be able to get thru the mud, it would be pointless to snorkel it

 

If you only snorkel the intake and leave the exhaust alone you should not need to rejet. As for the tires I would at least add a lift kit 2" at most and go with 26" tires. Mudzillas are OK for waht you are doing and if you go with a more agressive tire you start to break things
