Brute Force snorkel questions

Roody2010-08-11 16:26:30 +0000 #1
Hey everyone...

I'm snorkeling my Brute in the upcoming week using this site's instructions. Plastics are coming off tomorrow, buying the parts early in the week and then spending the rest of the week building the snorkels.

This is my first time snorkeling a quad, so I have some questions:

1) Is there any point in buying a Uni filter? I'm also putting an exhaust on the Brute and was planning on getting an aftermarket filter, but do the snorkels defeat the purpose?

2) What size piping should I use? I know the instructions on here say to use 2" but I've read about some people using 2.5" or 3".

3) How difficult is it to jet the carbs? I've never worked on a carburetor before, so I'm thinking it might be worth my money to just bring it to the dealer and have them do it so I don't mess anything up.

4) Any way to test watertight-ness before I ride it? The last thing I want to do is to snorkel it and then hit a mud pit only to suck water into the engine.

5) Is it really beneficial enough to buy a KFX700 CVT boot?

6) What vent lines do I need to run into the gauge pod? I remember seeing that people are using one of those "T" splitters but I can't remember what it's for (carb lines maybe).

Thanks for the help, everyone

I appreciate it big time. Can't wait to post pictures of my Brute once this set of mods are done

I dont really know about the filters but hear alot of good things about twin air.

If i was to do it again i would have gone with the 3" intake and may still redo mine that way before i do my exhast and jet kit.

dont know much about jetting the carbs as i have never done it.

after you get them done you can put your hand over the intake snork and it should die in 2 to 3 sec. that will tell you that it is sealed. i recently just pulled my rubber 90 off my air box and it was letting alittle by so i siliconed it when i put it back on.

looks like it would be easier.

yes you have to remove the white canister that is on the front of your airbox with three hoses connected to it. You will need to put a Tee in place of the canister and make sure that the one hose going up to your pod is there. you will also have to check and make sure that you diffs (front and rear) both go up to the pod and finally your gas tank. if you have the rear fenders off your bike and your standing on the right side where you fill it with gas you will find a small line that comes out of the tank and into a little canister. that is a check valve then it comes into a smaller hose and goes into the frame. pull the hose out of the frame and leave the check valve inline and run a hose up to the pod. that should do you right.

I like the kfx boot...but its not a have too thing. Yes the T is for the carb vent lines. Make sure you run up the gas tank, radiator overflow, carb vents. Make sure you seal the air box lid with RTV silicone good. The Uni filter is will help it get a little more air. Also, you will have to rejet with your new pipe. I can help you with that if you need me too. I would use a 3 inch rubber 90 off the air box and use 2 inch the rest of the way. To be honest most dealers just put what the instructions say as far as jetting and that doesn't work 99% of the time. I jet a LOT of Brutes so I can help you all you need me too. PM me if you need my number....

Thanks for the responses, guys! This info helps a lot.

So I should use 2" PVC for the CVT and exhaust but 3" for the intake?

I'll probably just use the stock CVT boot and bring the quad to the dealer/shop to do the jetting (makes my life a lot easier).

Once I know what size piping to buy I'll make the trip to Home Depot and start the building process

ya 2" for the cvt is what ya want, and your choice on the intake, but a lot of guys on here are changing too 3" for intake for a little more flow, I personally have had no problem with 2" but I am just running stock exhaust and havent had too rejet

Awesome, thanks for the help. Gonna buy the parts tomorrow.

I'm sure I'lll have questions along the way...seems like this is a hell of a process...
