Joe, there is supposed to be a foam sock filter on the end of the rubber intake hose where you put the tape. That will create the proper air resistance for the carb. You're welcome.
I'm seventy five and never had a ATV or Bike but for some reason I truly enjoy watching your videos. Maybe it's your calming voice how you narrate the work you do but it's addictive. Keep up the great work
Hee-hee, I've noticed the calming voice myself at various moments. I've occasionally viewed these videos totally alert and sat back on a sofa, and then found myself hearing but not seeing anything. Then I open my eyes. 😊
Yesterday I fixed an 03 Honda rincon for a buddy of mine. 5 of 6 bolts came loose inside the motor and ate the stator for breakfast. That was a fun one 🤣 my back is killing me today, I’d WAY rather just watch Joe wrench today! 👍
I remember back in the day when I bought a new one from the dealer back in 99 they told me the cams would go bad if you didn't use the special polaris 0w30 oil in them. I listened to their advice and used 0w30 Polaris oil since new and my dad has it now and it still runs like new. It has 28,000 miles on it. It is a sportsman 500 but basically the same engine.
My dad currently has the same quad from 1995. It is bone stock and has over 4k hours on it, and has never needed anything but gas and oil changes. Most reliable quad I’ve ever seen
@craigmorgan4676 nope 100% true best quad I’ve ever owned. Finally after 30 years of hard work the transmission is finally going. It has been worked it’s whole life and never gave us any fits
@@craigmorgan4676 they will if people would perform normal maintenance on them. I work on everything from motorcycles, snowmobiles, atvs, outboards, chainsaws, lawnmowers, etc and without question the worst are atv and chainsaw owners. They do nothing in regard to maintenance.
My cousin had one identical to this back in the day when they were new. He was a hardcore Polaris fanboy in those days, but all I remember of it was him CONSTANTLY fixing on it because it wouldn’t run or the 4 wheel drive had quit again or something. He doesn’t run Polarasses anymore! 😂
In the the mid 90s we had to pull Polaris' after they got wet because the belts would slip they was definitely junk in those days . There actually good fourwheelers now
@minnesotatomcat same, I like my YFZ450R and my TRX250X, my brother picked up a 04 Predator 500 and it's just been a chore, still gotta fix the leak to the carb
I just finished rebuilding a 1996 425. Cam ended up being wiped out on the exhaust lobe. You got lucky with this unit in very good condition. Thanks for the content
Didn’t see anything in the comments about this but if the tractor muffler has more air flow than stock,the carb will need a bigger main. When you restrict the air box, you are essentially running it at half choke making up for the lack of fuel. that being said I love watching your videos. I’ve learned a thing or two from you.
I was thinking the same. Cause and effect. Ditch the goofy tractor muffler and throw the OEM muffler back on. I bet it runs better without having to choke off airflow.
Joe, I really admire your dedication and determination in getting these machines, bikes etc. running again and really everything you set out to do, accomplished! You're showing that hard work yields satisfying results! Thanks for sharing & God bless! ~ Scott 💙🙏🏻👊🏼
2V, you landed a winner! When looking at that complex air box you can see some real tuning prowess went into the design. Live and learn! Great rescue! Congrats!
Nice you found an honest seller after some of the less scrupulous guys you've dealt with. The package of the KTM and this one was a winner. You had a couple of relatively easy and cheap fixes and can make some money on them. I don't ride ATVs or motorcycles but really enjoy your patient and thoughtful approach to fixing these machines. I've learned a ton! Great content as always!
Polaris tech tip. When diagnosing the fan simply unplugs under the passenger side fender well. Unplug it because it sucks enough juice to drain the battery in 5 minutes by its self. It will save on your cranking juice. Also the fuel “pump” is merely a device that only allows fuel to flow if the engine is running activated by air pulse. The fuel is gravity fed otherwise. The cams do get worn on these really bad as they aren’t oiled properly. Then go ahead on an add a jump to ground on the brown wire for the AWD so it’s never an issue. The factory mikuni carb is the best you can get. Only replace jets and parts as necessary . All the china remakes will never run right.
What would you advise on the engine oil? Is 10W40 motorcycle oil good enough to protect the cams or should you use some car motor oil for best protection since this vehicle doesn't have wet clutch? Some people above say to use 0W30 or 0W40 motor oil. Thank you.
I am addicted to your videos. Your patience and knowledge is amazing!! As a medical person, PLEASE open the garage door BEFORE you run those ATV's. What state are you in?
Don't remember when i came across your videos but i enjoy them. I bought an 2005 Bruin 350 from a friend and had it little over a year now. It's been pretty reliable and helped out quite in April and May this year after a tornado and pretty sure there was in May
Great find for your fix. Had the same thing on a 2 stroke atv I fixed 12 years ago. I had to zip tie a rag between the carb and filter. Weird it needed more resistance for the carb to work correctly.
I had a similar issue on an old Kawasaki street bike with CV carbs. I replaced the air box with Uni Air Pods, and the air flow was too great. I blocked about 75% of the Air Pod with aluminium flashing, and it ran perfect.
I just joined this week and am a DIY polaris fan. Really appreciate and enjoy your videos. Thanks again for your great videos. There are a lot of people that would learn from your video quality and paying attention to detail 👍👏👌💯😃
You sir are a saint . You have a new subscriber for this video alone . I’ve just wasted a day trying to get a proper answer online about this and exactly where it’s located. And at last I come across your fantastic video . I’m positive after tomorrow all will be fine again in my motoring world, thank you so much 🙏🏼👍
Cant blame him for picking that muffler haha. Unless its a Honda i find older atv exhausts are either hard to find or they're so expensive its not even worth buying.
The way I found your channel was a video you did on a Magnum 425 right after I bought one. Very good timing for another 425 because I can't get mine to run currently. This was a nice refresher on some of the things to check and how to fix them. Thanks for the video
One thing I noticed is before you took the plug out, you should have blown out the hole. When they are in there stuff falls in but you already know this. She’s a runner.
My first quad was a 330 magnum. What cold blooded pig that was! But low range on it was an absolute beast when i had to pull anything. Never again will i go back to a straight axel utility quad though, my back couldn't take it on the trails. Love your content from the UP of Michigan!
I worked for a Polaris Dealer back when these were new. They have had carburetor issues from the start. If your filter holder repair don't hold you can get that and the belt cover after market from Amazon. Back then Polaris did not sell oil they called for full syn after the cams started wearing out and atf fluid in the front hubs. You don't even need Motorcycle oil because there are no clutches in the engine and oil weight depends on where you live 10w30 is fine most of the time.
So Polaris engines are not that picky about the oil type? I have a Polaris Magnum 425 6X6 but since i've always heard that it always should be used Polaris oil in Polaris 4 stroke engines i haven't used any other oil. Is it the same for transmission oil or the oil in the front hubs for Polaris ATV's and UTV's too that you can use other oil types without any problem?
@@BSS22193 Polaris Atv's are not picky about there oil as long you run synthetic oil. Transmission runs the same oil as the engine, The newer UTV's are picky about the oil weight if they call for a 5W20 use 5W20.
@@Proudpapaify Thanks a lot i understand! I have been thinking about this a lot of times when it comes to service my ATV. But can you use the same oil in the front hubs as you can use in the transmission on these older Polaris ATV's or do they need any other type of oil?

Rubber (resistant to fuels) is normally attached to metals or nonmetals surfaces by the ad of painting the metal parts in areas where you can see it shall be attached. Let it dry. Apply the rubber part to the painted metal area and supply some pressure but mainly heat will do the cure. The paint is a special dedicated glue to ad/cure the contact areas
Hey Joe, I just found myself quite a few projects at my neighbors farm. Inside a shed they havent opened in years was a polaris magnum 325 and Indy lite 340 and a phazer 500 so hopefully i can get em running.
i have had the same issue on my quadrunner 250 and it was my carb bowl gasket was not sealing properly anymore as soon as i changed it it ran like a charm
Inherited the same quad as a basket. Had to find a carb and throttle. Finally started but wouldn't run faster than an idle. I read this was indicative of a cam with a worn exhaust lobe. Pulled the cam and sure enough it was worn to almost nothing (how is that possible? Did the previous owner just idle the engine endlessly?). Anyway I replaced the cam and it ran fantasticly.
Had a Suzuki quad that wouldn't run at all if the air box wasn't completely sealed. Got it for 250$ quadrunner 230 I think.still you got a heck of a deal .
I had the exact same problem did all the same things you did to try and fix it though it was my air box Turned out to be the intake boot o ring was sucking in just a bit of air . Runs perfectly now maybe give that a try
Thise tractor mufflers work quite well on atvs surprisingly. I have one on my wolverine with the combination of a mower one at the back of the atv. Its so quiet you can hear the air being sucked into the carburetor.
I saw his one with the bike on the back of the truck I hoped you’d work on it today . I’ve had one for a year trying to get it right . Would die backing up wasn’t cutting out in reverse fan great idling around but full throttle or against a hill it would cut out I totally went threw it new valves cleaned carb new cam everything was good new fuel pump coils stator still ran crappy got a used regulator CDI and Rev limiter still crappy . Found a 180 main jet in it and got a 140 and it ran great then . What a pain it was and it is now back after a couple months with no spark . I was really hopeful you’d need to do more to that one . Wish I could come over and say help !!!! Also that’s one of the fastest ATVs I’ve rode .
2:23 "Have no fear!! UNNNNDERDOG is here!!" I think I just dated myself... I had this EXACT issue with my golf cart. Turned out that mud dobbers had build a solid mud damn blocking the air passage tube after the filter. I couldn't see it because it was on the bend.
The few times I've pulled the carb off my of my 500 Scrambler that polaris carb mount as aggravated me, thankfully this one is a bit easier than the scrambler
Man for how young you are you know tons about how these machines work, I know you look Alot of stuff up but for doing this on your own for so long you always get it right 👍 you inspire me to start my own business doing this stuff but in the area I'm in it's very unlikely. I always enjoy your videos and learn from them your the best man I very appreciate you and what you do,, and congratulations to finally having a family bro not many you're age get to have a wife and child. You are the best 💯👌👍👍 keep wrenching my friend.💯
Check your intake manifold. The rubber comes loose from the aluminum and creates an air leak if any pressure is applied to the carburetor that would open the gap.
Another great deal. That has to be the best $200 You've ever spent. Ya it's gonna need some tires and that clutch cover. But, regardless what a good buy. Excellent work Joe💪😎
It's lean, by adding the tape over the pipe your choking it thus the carb pulls more fuel less air. Raise the needle if its a clip type or go to a slightly larger jet/mixture.
fantastic !!!.. it can also be simple Joe.. Vinny was very excited.. still honest sellers who don't rip you off .. the only thing I would replace is the silencer.. top Joe.. you deserve it really..ps..how is the ATV right outside your garage? engine...I'm really curious about...greetings
I think with that diaphragm being loose, ya'll can drill a tiny hole in the connecting pins and put tiny screws in it for a firm fit. With that air box with the broken supports I think if ya'll scratch it up with sandpaper then spray it with brake cleaner ya'll can use that hot wax, but it is really plastic you can put a good weld on with plastic sticks in hot wax.
Recently came across your channel and i must say im highly impressed with your mechanical skills and i absolutely love watching your videos they are definitely entertaining and informative.
You shouldn't have to tape the intake to make it run better you know that. You're too good to be doing that! Taping intake means the carb needs to be richened up ,but first find a new intake box ,then richen the carb. It's not like you to half ass something, you always do it right.
If you remove the slide there are two security screws to remove the main jet housing in the carb. There are two o-rings on it that rot and cause this issue.
Hey Joe , i have the same machine, its very sensitive to airbox and air filter and even the intake manafold, and mine did the same with bogging until i found a small bent part of the intake manafold, once i fixed that it was fine, the only thing i cant figure out is front right hub wont go into 4wd.
Kinda makes sense if the air box is leaking your losing vacuum. The slide works on vacuum. I never had one with that type of carb. $200 quad that runs. Would love it to putt around my yard.
Double check fuel pump. Seemed weak from the clip. If that's weak, will give the same symptoms. Had same issue on my 500ho. New aftermarket pump is cheap from Dennis kirk
That wheeler being that fussy on the air in, you wanna bet that teactor muffler is too restrictive also? Also I'd coat the whole outside of air box with thin layer of silicone where the cracks are, or entirely. Great find!
I have the same wheeler with the same air intake issue I took a foam filter and put it over the intake inlet were you put the tape and it helped. I was hoping you would do some troubleshooting on the radiator fan. Mine is not working haven’t had time to troubleshoot it yet.
Dude, your fleet has outgrown your shelter capacity. You need a pole barn in that area next to your yard! Would make for some cool content and give you much needed space
Most ATVs need to have the belt cover on for it to run properly and the belt needs to be in good shape to get proper rpms the cover has a breather and it's meant to cool it properly as well
Another great video. Maybe you should experiment with some plumbing pipe and develop an airflow reducer to sell to Polaris owners as a plug and play fix
The problem that you have with it is that tractor muffler is causing restrictions with the airbox off it's allowing the fuel mixture to change so it's running better but your problem is the muffler
On my 99 400 EX whenever the intake boot (between the carb and the air filter) comes loose from the carb it doesn't want to start, It just coughs and spits. Basically the carb would get too much air and not enough fuel. It was a mystery what was going on at first because everybody was telling me to take off the air box lid to let more air in to make the quad go faster, with no concern for installing the proper jet afterwards. I have dumb friends & sometimes we have to learn the hard way 😁
Random observation... If everything checks out, as appears to be the case, then I'd start looking at what's changed or are there aftermarket parts in play. In this case, the only thing non-OEM that appears to be on it is that janky tractor exhaust. Wonder if that thing is too restrictive or something similar and is the source of the issue? You've proved that it's an airflow issue with the work you've done. My next step would be to look at the exhaust.

Where exactly cuz I bought in that was beat up gettin it fixed up so i don’t think I have it either
Polaris got rid of that foam due to it crumbling and clogging carbs causing more harm than good.

Man for how young you are you know tons about how these machines work, I know you look Alot of stuff up but for doing this on your own for so long you always get it right 👍 you inspire me to start my own business doing this stuff but in the area I'm in it's very unlikely. I always enjoy your videos and learn from them your the best man I very appreciate you and what you do,, and congratulations to finally having a family bro not many you're age get to have a wife and child. You are the best 💯👌👍👍 keep wrenching my friend.💯
Got a great deal. I would still look into a new airbox. Thanks for sharing.
Check your intake manifold. The rubber comes loose from the aluminum and creates an air leak if any pressure is applied to the carburetor that would open the gap.

Any idea on this one?
This could become a good backup utility machine when you do landscaping, gardening, ice fishing, etc.
My grandfather has that quad. It’s a pretty nice machine.
Another great deal. That has to be the best $200 You've ever spent. Ya it's gonna need some tires and that clutch cover. But, regardless what a good buy. Excellent work Joe💪😎
thanks Joe for the help. I have 425 magnum 6x6 i had hard time tuning it this video really help thanks again!!!!
Another successful fix, good job Joe!
It's lean, by adding the tape over the pipe your choking it thus the carb pulls more fuel less air. Raise the needle if its a clip type or go to a slightly larger jet/mixture.
fantastic !!!.. it can also be simple Joe.. Vinny was very excited.. still honest sellers who don't rip you off .. the only thing I would replace is the silencer.. top Joe.. you deserve it really..ps..how is the ATV right outside your garage? engine...I'm really curious about...greetings
I think with that diaphragm being loose, ya'll can drill a tiny hole in the connecting pins and put tiny screws in it for a firm fit. With that air box with the broken supports I think if ya'll scratch it up with sandpaper then spray it with brake cleaner ya'll can use that hot wax, but it is really plastic you can put a good weld on with plastic sticks in hot wax.
Recently came across your channel and i must say im highly impressed with your mechanical skills and i absolutely love watching your videos they are definitely entertaining and informative.
nice find you cant get much for $200 now a days -- great video like always ---
Solar panel electric fence will work great for your garden 👍
You shouldn't have to tape the intake to make it run better you know that. You're too good to be doing that! Taping intake means the carb needs to be richened up ,but first find a new intake box ,then richen the carb. It's not like you to half ass something, you always do it right.
He half asses shit all the time
That spark plug tester is cool as heck
I think Vinny was a little more interested in playing on that beautiful day 👍
I need another 400 but mine was two stroke I do still have a 250 trailboss live that beast
Sometimes I think vin is the real star , and you are the comedic side kick😅
If you remove the slide there are two security screws to remove the main jet housing in the carb. There are two o-rings on it that rot and cause this issue.
Hey Joe , i have the same machine, its very sensitive to airbox and air filter and even the intake manafold, and mine did the same with bogging until i found a small bent part of the intake manafold, once i fixed that it was fine, the only thing i cant figure out is front right hub wont go into 4wd.
On mine the neck for the air box would flatten out cutting off the air flow. I threw it away and bam fixed.
Kinda makes sense if the air box is leaking your losing vacuum. The slide works on vacuum. I never had one with that type of carb. $200 quad that runs. Would love it to putt around my yard.
Never seen that tool for welding plastic back together. Hope you have a link for this tool, if not can you add it please. Thanks, Mark
Double check fuel pump. Seemed weak from the clip. If that's weak, will give the same symptoms. Had same issue on my 500ho. New aftermarket pump is cheap from Dennis kirk
That wheeler being that fussy on the air in,
you wanna bet that teactor muffler is too restrictive also?
Also I'd coat the whole outside of air box with thin layer of silicone where the cracks are, or entirely.
Great find!
Two hundred bucks of fun....nice work youngster
Vinny shook his head no right from the start. Vinny always knows.
Did a top end on one of those Magnums for my brother in law, was a big pain in butt.
Vinnie with the big jump off the trailer.....cool pup
I have the same wheeler with the same air intake issue I took a foam filter and put it over the intake inlet were you put the tape and it helped. I was hoping you would do some troubleshooting on the radiator fan. Mine is not working haven’t had time to troubleshoot it yet.
Dude, your fleet has outgrown your shelter capacity. You need a pole barn in that area next to your yard! Would make for some cool content and give you much needed space
Verify power at the junction before buying lamps. It could be the switch or fuse since all lights are out.
Carb problem. It’s using the air resistance to pull more fuel out the float bowl or to pull slide up
Most ATVs need to have the belt cover on for it to run properly and the belt needs to be in good shape to get proper rpms the cover has a breather and it's meant to cool it properly as well
Another great video. Maybe you should experiment with some plumbing pipe and develop an airflow reducer to sell to Polaris owners as a plug and play fix
If you don't want to replace the seat cover, you can use a air mattress patch on it.
Make a little test track with obstacles on your land. That would be fun to see.
The problem that you have with it is that tractor muffler is causing restrictions with the airbox off it's allowing the fuel mixture to change so it's running better but your problem is the muffler
On my 99 400 EX whenever the intake boot (between the carb and the air filter) comes loose from the carb it doesn't want to start, It just coughs and spits. Basically the carb would get too much air and not enough fuel. It was a mystery what was going on at first because everybody was telling me to take off the air box lid to let more air in to make the quad go faster, with no concern for installing the proper jet afterwards. I have dumb friends & sometimes we have to learn the hard way 😁
Maybe try a different carb jet, if you had to choked down the air, could be jetting issues
anyone else hoping they are not the next person to take off that oil filter? lol.. wow, joe. cranked that thing on..
the 425 from factory are jetted wrong, I find that sometimes if i take the rubber part off the airbox it runs perfect.
When in good shape those AMS Swampfox tires are excellent atv tires
Random observation... If everything checks out, as appears to be the case, then I'd start looking at what's changed or are there aftermarket parts in play. In this case, the only thing non-OEM that appears to be on it is that janky tractor exhaust. Wonder if that thing is too restrictive or something similar and is the source of the issue? You've proved that it's an airflow issue with the work you've done. My next step would be to look at the exhaust.
Maybe part of the airbox is missing at intake is there suppose to be a top of some kind that does the same as your tape trick
