Uni Air Filters are the only way to go. Even thought both the Uni and K&N filters both require an oil the K&N is a paper type element and they seem to get dirtier quicker then foam filters. Nice video! Gonna take a look at my father's 2012 Sportsman 500 to see if his air box lid has the same restriction. His lid does look different then the 2011s in this video.
Good video! Thinking about doing this to mine. When I have the air-box lid on it now the motor bogs way down and runs super rich, not getting nearly enough air, almost as if there is a clog in the pipe but there isn't one.. When i remove the air box lid it runs like a champ, it is just really noisy.
i would, for sure... just be very sure about telling the viewers to re-jet. Another way to go, is to give the size of the new jet that you will use... take care
Wow great video friend thstyou did there. We are new to ATVing and just looking at other people video and thought just stop and say hi! I own a Grizzly 660 and my friend has a Arictic 500 we just like have fun and taping video when we can! :-) Hey keep the great videos comming it nice to see what other folks are doing in Quad world!
I was in the Black Hills with my 02 500 HO and It had no power. It started acting up at home which leads me to believe something wrong was going on mechanically. I took it to the Polaris dealer in Belle Fourche SD who first thought worn camshaft but changed his tune and said it was my clutch advancing to full speed too early after driving it for awhile he asked if he could do a modification to the airbox to fix the problem. He drilled two 1.25" holes side by side in the air snorkel on the underside next to the air box cover and it was a totally different machine. Where I thought I was not getting enough fuel here I was not getting enough air at 6000 ft. I did ask him about my clutch and he said nope it was not getting enough air. I will have to check the space you are talking about. Is it possible you might introduce too much air into this setup?
you seem very knowledgable on polaris atvs, i have a 2006 polaris sportsman 500 ho completely stock, it idles fine but when u give it gas it bogs and wants to die but if u give it full throttle it will run okay, it has a new air filter, new fuel filter and new plug in it so those cannot be the problem, any suggestions?
If you ditched that whole lid with that restricted intake tube seems like you'd gain a bunch of performance. As long as you were not running in deep water/mud.
Plenum volume being after the throttle blade? If so then yes, intake volume and runner length can do a lot to help performance, but that would all be after the throttle blade, and usually on bigger, multi cylinder engines. Messing with anything before the carb on a small engine drastically changes the effectiveness of the venturi and changes the air/fuel ratio. Luckily it isnt hard to re jet for the increased air flow potential by reading the plug.
nice video. I have a yamaha dt 200r 1985 dirt bike. it was parked up for about 3 years.i have a problem where the bike would run perfect without air breeder.as soon as I put the air breeder cover it have no acceleration. can this be an air box problem or carburetor?
Its a 2011? And its carburated? Thats kinda odd, as 2006 was the first year of fuel injection on the sportsmans. Unless the fuel injection system involves a carb
I changed carbuator on my 1999 polaris it runs like carp put duck tape over half the intake on air box it. Runs great was getting to much air any suggestions
Ive got a 2013 white 500 HO and want a little more growl out of it. If i were to drill 1/4 inch holes not in the bigger part but the smaller pipe that comes down and curves (the one thats about a inch or so in diameter) Would it make it easier for water to get in?
Hunter Wroten those are dogs they need something done and I think it would wake them right up. I test drove 2012 800 Sportsman it had 700 miles I believe maybe 600. it was a no power steering model that's why I'm not sure on the year but compared to the 2017 that I test drove literally 15 seconds later it's a world of difference that 570 with 1 mile on it felt like it was way snappier it even felt faster all the way to 40 miles per hour or 45 miles per hour that's all the faster I have room to go so I don't know about past that but I went with a brand new 2017 570 and so far with only 10 hours on it I do not regret it and it was a plain Jane model only option was fancy Wheels and power steering. just my two cents. if you're not sure how to get a little more power out of that 800 and you're not text savvy try getting ahold of Lake Mills Motorsports in Iowa. ask for Matt lewerke otherwise just go on the forms and on CZcams obviously good luck brother

I will try this on my 07 sportsman 450- k&n jet kit. Just saw your exhaust mod vid--kickass !!
i would, for sure... just be very sure about telling the viewers to re-jet. Another way to go, is to give the size of the new jet that you will use...

I can't believe how much crap and pine needles gets stuck up in your air box. I don't think I've ever found anything but dust in mine.
What size of jet would you use after doing the exhaust mod?

I have the same problem any help you can give would be great
Cool, basically porting an airbox
If you ditched that whole lid with that restricted intake tube seems like you'd gain a bunch of performance. As long as you were not running in deep water/mud.
Actually, these quads like to have plenty of vacuum pre carb. If you remove it or make it larger you HAVE to re jet.
kx519 correct me if I'm wrong but I believe engines like some plenum volume depending on the type of engine and its application

good vid... thanks bud
lol... ok thanks........... and have a look at me doing Daytona at 160 MPH...... that was awesome..

EFI Was an "upgrade" / Option.
I did not want to pay the extra $850 for that upgrade at the time.
I have that same problem on my 1999 sportsman figure anything out. im going section by section and doing a full run through.
I changed carbuator on my 1999 polaris it runs like carp put duck tape over half the intake on air box it. Runs great was getting to much air any suggestions
Do you know what kind of restrictions are there in the polaris sportsman 500 EFI 2012?
Thanks!
what if it's fuel injected? can't rejett
I will adjust itself, it will adjust itself, it will adjust itself
I have an 11 and mine was not like that
My dads 2012 550 efi eps looks a bit different.
You have to rejet with efi?
Depend , most ppl do not as they auto adjust for the most part.
Did you take off your sway bar?
If you grind this out to make more air what this gonna do.. more horse power
I have Videos on Exhaust And Jetting Also , Made a GOOD Amount more power.
Or if you quad run rich or in the accélération the quad lag

So if youre only doing this, you dont need to rejet? Thanks:)
If you do the exhaust mod in my other vids yes you do
I have a 07 sportsman 800 EFI I wouldn't have to rejet it would I? bc it is EFI

Dude you are funny
J
Would this be the same concept for a 2004 Scrambler?
Sorry not 100% sure But i bet very close.
what if it's fuel injected? can't rejett
