That sway bar delete looks interesting, and I could see this being quite beneficial as I’m more of a 4-Low type of driver and really enjoy having the wheeler planted on the trails when going through extreme obstacles. I may look into this for my Brute Force, thanks for sharing! Take Care!
Hey Andrew ! yeah if you ride like me or even slower (4WD Lo) then the swap bar delete would be a great option, I know I wont go back. Cheers buddy !
BRILLIANT VID, GREAT TO HAVE SUCH A KNOWLEDGEABLE FRIEND TO HELP LOOK AFTER YOUR QUAD, MICK FROM UK,
Hey thanks Mick ! yeah Evan is a great guy and smart too !
Just installed the EHS Tuner / AIS Delete on my 2019 and can tell a big difference in the Engine Temp.
Hey ! thanks man ! I cant wait to get the bike out for a good ride to test it out.
When I used to ride my Polaris Sportsman 400 I removed the rear sway bar and really enjoyed the extra articulation and traction. If I wanted to go fast and needed a sway bar, I sure wouldn't have bought a 4wd utility quad! Nice video of all the mods and looking forward to more riding/camping videos when you're ready to go! Take care! Pete - KI7LIL
Thanks buddy ! I cant wait to get out again !
Peter Kunka Right on. No one buys these things to rip around at 60 mph lol 😂
So glad you finally did a tuner. I also run the tip also on my exhaust so the engine can breath and not be restricted. It was to loud at first till I stuffed steel wool in the exhaust. My only intentions was for the motor to run cooler. Oh my did it make a huge difference. I have placed block of plates for the AIS on my street bikes but this is so simple. Pull the hose off. Put a rubber nipple on where the hose attaches, then slide the hose back on it. Done. Well mines under warranty so that's why I did it . Can't see it. I am curious to know the advantages to removing away bar. May be something I would like to try. Like I said huge difference.
Hey buddy ! yes those 708's run pretty hot, so I needed to cool it down, and so far my fan doesn't come on half as much and I find my throttle response is better, did you find that?
I tried my friends Grizzly in another video and his sway bar was removed and I really liked it, it lets your suspension work fully but just need to be mindful for the high speed stuff.
@@Maritimer Yes, my low gear goes much further, mid is much stronger but be mindful my exhaust has been altered. R2 Tip and packed muffler with steel wool. Mine is like another bike plus runs much cooler. Take care think I'll go for a ride. An unusual 63 today in N.C.
Sure is nice having a friend with a warm work area ! Hoping Christmas was kind to Ya's ! ATB T God Bless
Hey Terry ! yes it is for sure ! he's got a really nice spot ! thanks again and Merry Christmas !
great vid. ik im a kid but im really into this stuff
Hey man ! thats awesome to hear ! much better than spending all your time playing videos game ! thank you !
@@Maritimer im saving up for a grizzly
Thank you for posting this helpful video
Hey ! no problem, thank you for watching !
Interesting.
I'd love to try one of those tuners on my Honda, but I'm not a believer. From everything I've read on the Honda Forums, they don't do anything for the Honda's or if they do, it's so minimal that the cost of the tuner isn't worth it.
Thanx for sharin' bud!
edit: Oh, and I almost forgot . . . HAPPY NEW YEAR!!!!
Hey Q !! Yeah your honda probably rungs good anyways, mine has a Subaru 708cc motor, and its leaned right out so it will pass emission testing.... so the EHS Tuner will adjust the fuel/air ratio so it doesnt run to lean... in turn making the motor run cooler, and prolonging the life (Hopefully) haha Happy new Year !!!
@@Maritimer
What? The Grizzly has a Subaru engine in it? I had no idea. That's cool! Subaru makes indestructible engines.
Yeah !!! So Yamaha had the 686cc motor from 2008-2015 then it wouldn't pass new emission testing. so they contracted Subaru to make motors from 2016-2018 (3 years) they made the 708cc and the 2016's had some issues with burning oil very early into their life, even some 2017+18 do it too. Mine has been great. but it does run hot because it runs so Lean. So to make it run less lean (rich) and cool it down EHS tuner changes the fuel/air ratio and makes it run cooler. it's not for power or performance really.
The tunner is worth every penny it made my 2020 grizzly 700 run 10 or so degrees cooler and has more power it helped alot I was sceptical at first but it made a big difference on my machine
Hey Tim ! Thats awesome to hear man ! I didn't notice any power difference, maybe the throttle response got better but no real power gains. Maybe your 686 is just better than my 708 hahaha I find mine runs a lot cooler now too.
I was curious about how your atv feels off-camber/side hill without the sway bar. I like the idea of more rear suspension travel and more comfortable trail riding which i do, but i also hunt in the hills with no trails and to recover game.
Hey buddy, the bike feels basically normal ! I don't notice too much difference to be honest, I was out for a 70km ride money and it was super smooth but our trails right now are snow covered so... it makes it smoother..
I think it's a perfect mod for you than, it will let your suspension work how it's supposed to, just remember it's not there for those time you do go at a high speed...
Well, well,well... bought a brand new 2019 ATV and the first thing I did was talking off the warning ⚠️ stickers. lol 😂. Nothing like a good old man tune up 🚑
Hey !! haha yeah I don't know why I waited so long to remove them lol it looks much better !
Rhetorical question, how different in the highspeed corners did you find it without the sway bar?
Hey Don, yeah I get that question a lot, I don't notice it too much, it definitely leans more than it did, but I just lean into the turn and there's nothing to worry about.
Is there anyway on turning tick over down and stop it Erving so high on a trail ride . I’ve just got a new 2022 700 and I’m not liking how high it revs when riding trails
Hey man, I don't think thats a possibility with the newer machines being fuel injected, but you would look at different clutch weights, I know some people will do that. you'd have to do the research, I don't know much about it. sorry. Cheers !
Hey Maritimer, how did you affix the EHS tuner to the lid of your glove box?. Great video!!
Hey! Just used some velcro tape. I think it's made by 3M it's pretty good stuff ! thanks man !
Has the EHS tuner been working out ok? I haven't had any overheating issues with my Grizzly but as soon as I purchased it I added Royal Purple Ice to the coolant. I'm more annoyed by the popping and faring the exhaust makes when letting off the throttle or descending hills under engine braking.
Hey buddy ! Maybe I will give that Royal purple a try too. is it OK for the Winter or do I need to change it? Try the AIS delete mod for the popping (I know we talked about this in another comment on another video) but maybe someone will read this. haha
@@Maritimer Yes we did, oops! The Purple ice is ok for year round use. Where did you buy your EHS tuner? Is there a Canadian source?
How are you liking the no sway bar? Looks like you messured the lift after removing it. Do you have the before and after measurement?
Hey ! yeah I love it, I will never go back haha we did but with no weight on the bike it wasn't a true measurement. You could always disconnect yours, then zip tie it up out of the way, go for a trail ride to test it and see if you like it.
The New Jeep Gladiator has the ability to quick disconnect the front sway bar, and they are for off road, so it must help.
How did you guys do man work without having wobbly pop? Anyway another good video man, I'm interested to see how the tuner works.
Bahahahahahah it was about 10am when we filmed and Evan isn't much of a drinker at all haha thanks so much ! tuner has been good, my fan doesnt seem to come on half as much as it used too, and my throttle response has improved also.
Hey man great video! I ride a 2018 grizzly and am looking into doing a few of these mods as well. I was wondering where you purchased your EHS tuner, and if it was from the states what kind of shipping and duty fees did you pay? Wicked content!
Hey Mitch ! thanks a lot man ! Yes I ordered my tuner right from EHS, as far as I know it's the only place you can get the EHS tuner is directly from them (website)
I cant remember for the life of me how much it cost or anything. I doubt duty would be much b/c it's not very heavy.
Could you do a video out on the trails of the quad flexing ? Thanks
Hey, I sort of show that in the video, but I dont have any other video of the bike flexing that much, except for regular trail riding.
@@Maritimer gotcha thanks
What years has the exhaust hose connected to the fresh air intake. Is it on the 686, 700 2014 model?
Happy new year, Santa already gone so no Merry Christmas this time.
Hey man ! 2008-2015 I dont believe have the AIS. 2016-2018 have the 708 and the AIS. 2019+ they went back to the 686 motor and i'm not sure if it has the AIS or not. Merry Christmas to you too !
@@Maritimer they do have it I just did it on my 700 2019
Hey I'm here in New Brunswick also , I have a 19 700 Kodiak , how are you liking the sway bar delete I'm thinking on doing it to mine!
Hey ! Yeah I love the sway bar removal, I really like how it lets your suspension work how it's supposed too, I'm not planning on going back.
Be sure to report back on the seat of your pants felling on the three mods you just did, curious of your findings! Thanks
Hey Rick, I will for sure man ! SO far; Tuner seems like my fan doesnt come on half as much and my throttle response seems to be better. AIS Delete; the backfire/popping sound is pretty much all gone. and he sway bar lets the suspension really travel in technical terrain.
What type of tuner did you use and what type of improvement would it do to my 2019 Kodiak?
@@kennethrobinson8442 Hey ken, it's an EHS Tuner (it's in the title) there is a link in the description to the EHS website.
I'm not sure what it would do for your Kodiak.... I believe we have the same motor so I'm guessing it would have all the same benefits. (motor runs less lean, cooler)
Great video guys, but I'm a bit confused about the EHS tuner? At the outset of the video, you say that it wasn't really installed to improve performance, but in your comments and replies here, you say that it alters fuel/air mixture, so doesn't that improve overall performance, as well as serving to cool it down? Thanks.
Hey man ! yeah it changes the air/fuel mixture which makes the motor not run so hot (less lean) so it's not really something to make it rev more or get more fuel or something like that.
Does the 686 run lean two
#PROLyFEtheLONGofIT HAHAHAHA! Quite a basement! 2XMRs, DRZ, X2, a sled, and a couple Grizzers.. Cool vid bud! I've personally always found that you gotta add just a touch of fuel to most programmers.. Be interesting to see if you go the same way with the EHS..
I know eh !!!! Im always jealous when I goto his place haha
I'm not understanding the AIS part. You took the hose off....What do you do with the rest of the hose? I get that you plug one end but, the vid doesn't show a stub on either end. Can you elaborate more on that. 2020 Grizz I just bought. EHS tuner came today with airbox filter mod. Thanks
Hey man ! thats awesome, congrats on the new machine ! So the AIS "delete" mod is just plugging that hose I showed in the video then putting it right back on where it was before.
AIS (Air induction System?) just pumped air into the exhaust to burn off unburnt fuel in the exhaust, which will cause popping/backfire sound. It's a way for Yamaha to get better emissions out of the motor, but the popping sound is annoying.
@@Maritimer So you're saying and in line plugging of the hose.
Have you done the air box mod yet? I noticed I had dust getting by so I put the new box on. So far so good. Only have 150 miles on the new box. I'm probably going to do the ais delete since you say it helps with the pop that I cant stand. I have a 19 and I've not done the EHS tuner yet but i love how you showed just how easy it is to do.
Hey Buddy ! NO I havent done that mod yet, I'd like to though ! But I also haven't seen any dust in my air filter either... I did the AIS and it helps but it still pops a bit.... which I also hate. the Tuner is great, the bike runs cooler, the fan comes on less and when it comes on it doesn't stay on for the whole ride haha I'm glad it helped ya man, it's really easy to do !
@@Maritimer if you dont follow anyone ever you should be ok I think. I checked mine after sealing it with grease and around 700 miles I noticed the dust in there. I have 150 with the new filter now and i should check it tomorrow.
What mod did you do anyway? Buy a new air box or mod you stock one?
@@Maritimer I bought the yamaha box with the updated filter setup that ehs sells but I kept the stock lid instead of buying their lid which is more of a racing one I think if I remember correct. You can buy just the parts from them and cut your own stock box to install them if you want, but I didnt want to screw it up.
thanks man, I may look into that !
Is there a EHS tuner for the 2017 kodiak 700
Yes I believe they do ! I put a link to the EHS site in the description.
So does the EHS tuner actually help make the bike run cooler?
Hey man ! Yes I find my fan doesn't turn on half as much, the tuner changes the air/fuel ratio making it run less lean or richer, which in turn makes the motor cooler.
What was the reason for taking the back sway bar off.
I answered it a few times in pervious comments but short answer is it allows the suspension to travel to it's fullest without having a wheel come off the ground.
Hey James, great vid, just wondering the reason for removing the sway bar? Happy New Year buddy!
Pa Mil better off trail riding smoothness and control. Especially climbing hills keeping all tires on ground and not being as tippy in flexing situations
even explained it pretty good buddy, it's nice for the trail rides for sure. keeps more tires on the ground.
So it's not bad for trail riding ?
hello did you find a difference to delete ais ?
Yup, it has seemed to stop pretty much all backfire/popping on deceleration. which used to drive me crazy.
What exactly do the AIS delete do? Like my header tends to glow, would it help that?
Hey Chris ! the AIS Delete wont help the glowing header, the EHS tuner would be better for that.
The AIS is just a thing that puts cleaner air into the exhaust to help it pass emission tests. but it's always causes the popping on deceleration, by blocking it off it cuts back on the popping.
Maritimer thanks for the info!
hello have you change your muffler and clutch or just de EHS tuner
100% stock.
@@Maritimer thank you and love your video
I have the exact same machine (except in Green) and installed the EHS Tuner and an R2 Tip on the exhaust immediately. Only left them on for a couple of weeks and then removed both. A bit loud with the tip and I lost about 30 kms in fuel range. Now at almost 4000 kms, and bike has run great with no popping on decel and does not seem to run hot. This is just what I found, others may be different. Be curious to know if you find if your fuel economy goes out the window with the tuner installed. Stock I get approx 160-170 kms per tank.
Hey man ! you got 160-170km to a tank of fuel? that sounds a bit high... the most I've ever tried with my bike was 130km and it was pretty much empty, I've never heard of anyone getting 160-170km range thats awesome.
i'll keep ya posted !
It’s easy to figure out. You don’t have to run it dry . Begin with a full tank and go riding. Then divide the number of Kms you rode by the number of litres it took to refill the tank. That will give you the kms per litre. Then multiply that by 18.2 , the fuel capacity. I consistently get 160-170 kms and so do many other people . Read the forums. Like I said that is what I get you can get whatever you get. It was the same on my 2014.
@@Maritimer we have gotten over 150km on a tank on our 18 and 19 Grizzlies . The guage will sometimes say empty (no bars left) but when we fuel them up at a gas station they only take like 13 or 14 liters so there is still a good 4 liters left in the take even when the guage reads empty. I had a guy tell me he has went nearly 200 km on a tank. Logically it depends on how your riding it of course aswell. When we are on a long ride my wife and and always ride relatively easy you could say so to conserve gas basically . Great video btw
Did you order you ehs directly from ehs racing?. Just wonder how long it took to show up. Mines been stuck in customs for five days now.
Hey Scott ! Yes I ordered direct from EHS and mine came pretty quick if I remember correct, but there wasn't COVID going on either haha that sucks yours is stuck in customs.
@@Maritimer how much did you get dinged with duty...lol
@@scottbrake9129 Oh I cant remember now... i have terrible memory lol
Has your grizz ever stalled on you on a cold run with half frozen puddles ? Mine seemed like it wasn't getting fuel that well and then stalled started again but was up and down while on the gas ?I also put that same tuner in and ais block seems to work better definitely less back fire
Hey man ! no my grizzly hasn't ever stalled on me, that sounds weird, maybe an electrical thing if it happened in water... Yeah the backfire has pretty much all gone now, it's great.
Somtimes if water splashes on the motor. Steam will rise and get sucked into the air intake and stall the motor
@@steevesevan thanks good to know it was icy and cold so maybe that was all it was
@@ivanfitch9158 have you rerouted your vent hose that comes off the gas tank right under the seat? That hose runs straight down and vents right above the skid plate. When it gets under water, it can make it stall. Most are rerouting the vent up under the front rack with the other vents.
@Gatorman10 I have not tried that but I will now thanks for the tip 👍
How does the tuner allow you to run cooler without fan turning on as much? What’s the process?
Hey Kyle ! the Tuner will adjust your fuel/air ratio among other things, Which makes it not run so LEAN, which makes the engine itself run cooler. If your motor runs very lean (usually b/c its high performance OR in my case, they want it to pass government emission testing, it will run Hot, Have you ever ridden with sport bikes like a Raptor or 450R at night? their header pipes will glow red b/c they are running hot (they are higher performance motors).
I hope I explained that good enough, if not a quick Google search might be able to explain it better.
Maritimer I ride my kodiak 450 and my buddy has his grizz 700.. both new. Both correct fuel ratios from manufacturer. Yeah we ride at night. Got a 708 and 686 both never hot...it’s all good man. Just can’t relate
So You don't find the fan comes on, on your 708 more than your 686?
Maritimer I can’t really say, I’ve never driven them the same way for same amount of time to compare. But the fan seems to work well when on.
Hey buddy, how are you liking the sway bar removal now that you've got some seat time without it?
Hey Todd ! To be honest I don't notice it on regular riding.... especially in the winter, the trails are pretty smooth. I'm guessing this summer I will notice it.
Can't remove those warning stickers! That's like pulling the tags off a mattress, LOL!! Your quad looks so sweet in camo, nice and clean under those panels too. I shared your cleaning video last year with my son, hoping he see's the light and keeps his Brute Force clean after his rides. Hope you had a Merry Christmas.
hahahaha oh man I don't know why I waited so long to take them off, looks so much better. lol Oh we'll I hope he does too !! gotta keep the Rads on the brutes clean or they will have an over heating issue, just something to keep an eye on. Merry Christmas and happy riding with your Son !
Does the grizzly seem to run cooler now. Great video.
Hey ! yes it does for sure ! the fan doesnt come on as much and when it does it doesn't stay on for so long. Tuner was worth the money. thanks !
@@Maritimer where did you get the tuner from? Thanks in TX
@@masonxtentacion9093 Direct order rom EHS website. I think I put a link in the description but I cant remember.
👍📽
thanks Wayne !
What was the reasoning for taking the rear away bar out ?
Hey Chris ! removing it allows your suspension to travel further. for my style of riding (slower pace, trail rides) it's perfect, keeps more rubber on the ground.
if you do mostly fast pace, fire roads, ripping around corners then you might want to keep it on, keeping it on will stop body roll around corners, so less chance of roll over. BUT if you're an experienced rider, you know how to lean into the turns and you probably wont have an issue even at high speed cornering.
What is the AIS and what's the point of deleting it?
Air Injection System - it pumps air into the exhaust to help burn off excess fuel, which is the popping/backfire noise. they do it to help the motor pass emission testing.
What are the benefits of the ais delete?
Hey Nate, I think I mentioned it in the video but the AIS delete will stop a lot of the popping or backfire sound on deceleration. it blocks off the airway that sends fresh air into the exhaust which is used to burn off any unburned fuel..... which is the popping/backfire sound you'll hear on the 708 motors.
@@Maritimer yea, I'm kinda a fan of the backfires so I think I'll hold off. I was justing wondering if it was increased cooling or maybe a lil power.
What the big advantage to plugging that hose ? You going racing or something !!
haha stops the backfire/popping on deceleration on the 708 grizzlies.
Can you do a video discussing tires? Why you run Big Horns and what other tires you see people run often or what you would recommend. Thanks John
I run duro powergrip v2 as I mostly trail run and they are a good radial tire for the terrain I run on 90 percent of the time if you mud more often than a radial mud tire might be more what you want . New big Horn 3.0 look pretty sweet they have a directional front tire and more of the zig zag pattern for the back, I do find having the zig zag pattern in front it slips a bit more in the snow
I run kenda bear claw k299 cant beat them they seem to last forever ive got over 3000miles on a set an thats rock crawling asphault mudding u name it they excell in all conditions
Bighorns are a really good all around tire. There not great at any one type of riding. You have to pick a tire that matches you type of riding.
Thanks for the replies. I've been thinking about the htr bear claws but open to other options.
A guy I work with has those they are a very good tire and last a long time
Why do you remove the sway bar? As a mod
Hey man, I thought i mentioned in the video but removing the sway bar will allow the suspension to travel more, which keeps more rubber on the trail when you're riding technical trails.
the only real reason the sway bar is there was for high speed cornering.... people were flipping their machines b/c they weren't leaning there weight Into the turn.... all the weight would naturally goto the outside and the bike would roll over.
The new Toyota Tacoma and Jeep Gladiator trucks have quick disconnect on the sway bars to help with off road driving. I';ll never go back, I found it much smoother.
And how did you like it all or not ?
Yes Sir ! I like it so far. EHS Tuner seemed to improve the throttle response and my fan doesnt turn on too much, so it must have made the motor run less lean. the AIS delete has pretty much stopped all backfire/popping on deceleration. and the sway bar removal really lets the suspension work, and reach further, keeping the tires on the ground.
Maritimer my dyno tune on the power commander 5 improved the throttle response greatly as well, worth it for me . And the sway bar delete is a lot better I find as well. Glad your enjoying it
thanks man !
3:59 I think that connector is the intake air temperature sensor.
yes I believe you're right !
It's actually the injector, your plugging in a piggy back tunner, into your injector, which tells it to add more fuel
Why remove the sway bars? Just wondering
Same reason to do it on a car, better wheel articulation for a smoother ride and better traction offroad.
(At the cost of worse stability when taking corners at speed)
is exactly that, I did it on my 2010 and I am very happy with it, despite everything the stability remains good.
I think these guys pretty much explained it, if you look at the new Jeep Gladiator trucks, they have the ability to disconnect the front sway bar quickly for trail rides. it lets your suspension reach further while keeping wheels on the ground (traction) just need to be mindful of the body lean when riding fast.
Thank you I had no idea that actually pretty cool
maybe a dumb question but why delete sway bar?
Hey buddy ! I thought I mentioned in the video.. but removing the sway bar will allow the suspension to extend more, and it will keep more tire on the trail while the bike is articulating over different obstacles. The sway bar is really just there to not allow the suspension to "lean" while cornering at high speeds. (makes the bike more stable at high speed cornering)
But if you aren't a novice rider, you know to lean your body weight into the turn while at high speeds.... some people don't know that, and thats why they put the sway bar on. I'm really glad I removed it.
Oh okay gotcha, thanks for the reply
Check out MrCuervo racing videos on here, he will sell you a block off plate to totally eliminate the AIS, did my 2017 Kodiak, eliminated the solenoid and hose all the way to the airbox. Was pretty easy.
Hey ! thanks man !! I might check him out if my AIS block doesn't work, seems to be good for now though.
Looks like a premeditated insurance claim . ( the basement)
hahahahaha !!!! Maybe.... lol Doubtful though, he likes his bikes more than anyone I know haha
Now maybe just throw some Elkas on there.
Hey Buddy ! I'd love to have some Elka's but I cant spend that kinda money on it, especially b/c I'll probably end up getting a SXS in the future..... I wish I could have both.
@@Maritimer Roger that. Damn that reality stuff.
Why you removed the bar
Hey man, I thought I explained din the video but I could be wrong. I removed the sway bar to let the suspension be able to travel fully. It makes a great improvement on trail rides and slow technical trails. the only reason they put sway bars on is so when guys are riding fast around turns (and don't know enough to lean Into the turn) the sway bar doesn't allow the machines suspension to roll to the outside, along with the riders weight, which will cause a roll over. if you are experienced, and know to lean into the turns you'll have no problem.
@@Maritimer thank you
No Problem !! thanks for watching !
@@Maritimer cool I'm actually picking up a 2020 grizzly 700 eps se trading my Raptor 700r se
Nice !! I love the Raptors ! they are a surprisingly good trail machine, they have decent ground clearance for being a race bike (comparing to the LTR's and 450R ondas and stuff) My buddies had them when we were growing up, My friend still has his 770 Raptor (bored out) with a stroker kit in it, it's a wild machine haha
I think you'll like the smooth-ness of the Grizzly on a full day of riding over the Raptor haha
