This is just awesome. As a 16 year old boy who has a o4 400ex I would never dare to go near the engine. This has given me a lot of confidence to learn a little more about the engine and think about small power mods. Thanks I love your content.

Your skits are funny man! I'm loving this 400ex series, can't wait till the next video drops on this quad, watching the oldies come back to life is what I live for. There's not too many people doing it in the quad space either, besides maybe 2vintage.
Love how you're putting yourself in the shoes of someone with a budget really gives people ideas out there of what they can do with very little money! Love the video man cant wait to see how it turns out! Great content as always.
Poverty budget builds are the only builds I do. Much respect for you doing this series man. Its alot more realistic and reaches out to a much wider audience because not all of us can afford a several thousand dollar build.
I have a 400ex with a 416 bore and an 11 to 1 piston. It’s also got an hmf slip on and a stage 2 hotcam and an aluminum air box. The thing rips! I ride with my buddies on there sport quads and it keeps up just fine! Can’t wait to see this thing once it’s built!
I LOVE your channel and I love everything sport atv's. I first came across your channel when I was working on my banshee and then I picked up a 400ex and mostly like it more than the banshee. I've been waiting for a 400ex build for a long time. Words can't describe how excited I am, lol. Keep it up, man!
One of these days I think it’d be cool if you went on Facebook marketplace or something like that, found a cheap beat up looking quad and fixed it up the best you can on a budget. It’d be more of like a tips and tricks series and will provide a worse case scenario tutorial for viewers who may have to deal with something like that one day. Plus, you gotta love a good before and after pic.
This build series is gonna hit different cause we just sold a 400ex just like this in mint condition that we’ve had since I was born, so many memories 😢
@@TheHONDAKID48 what's sad is the way Mike handled the situation. He should be ashamed he let down the sport quad community and all the top quad fans. After everything JST did for Mike to turn your back on Justin like that was a lowlife scumbag move.
Micheal I have used rtv to seal the majority of my 400s engine and it’s held up for 9 years plus the time it sat when my dad stopped riding and it ran like a champ and still hasn’t blown
After your budget build. Go for a 440 big bore sleeve with +1mm kibblewhite valves, new seats and porting. Such a great air pump. My 2001 would beat tons of 450s. With the stock header and WB slip on(hugh stack of plates) Total sleeper ! I would deal with Powroll back in the day. Great people. Love the project Mike, keep it up buddy ! And... Maybe I'll bring my mobile ATV dyno over to your town someday.
quick tip. I had alot of ticking in my 1999 400ex and my problem was the auto decompression lobe on the camshaft. even if that's not the problem with yours, i still recommend taking it off. All you need is a shop press and it will slide right off. You can go look on you tube for a video. Awesome Quad!!!!
God I miss my 400ex. I had an 04 same color. With nerf bars, supposedly previous owner installed high compression pistons, rejetted the carb, exhaust, little things here and there. Thing was fast back in the day.
Its true sometimes you just don't have the cash to do major mods you have to work with what you have there's nothing wrong with that!! Love that your keeping with the $1000 budget. Keep up with the videos i watch all of them🤪👍👍👍👍
That brand of battery you purchased is actually pretty good, I run them in all of my bikes and have had no problems, if you keep them on a trickle charger when not in use for a long period of time they actually stay and hold charges for quite a while.
Your videos are my favorite on TH-cam man. I don’t miss a single one! If you want an aluminum air box/ battery relocation box for the 400 let me know!! I’ll send it to you!
Very realistic. I just bought a 520 Rubicon brand new I wanted a sportbike but couldn't find one in my state at any dealer I called. So I'm going to look for a 400EX in the spring
Should go down to the frame and clean up all that rust and give her a nice rattle can paint job!! Definitely would make it look like a completely different machine
You should do a full motor teardown once youre done with the whole 1000$ challenge.. I have a 400ex with a broken shift shaft and I have no idea how to repair it and I dont wanna take it to a shop at all
When cash is tight you do what you have to. Rather spend the $9 gasket kit than reuse. Great video and show casing the budget build. Definitely do a 416 kit with 12:1 piston with stage 2 cam, after
Hey mike on reusing those gaskets. Clean then with some rubbing alcohol Then get a can of permatex copper coat and you will be good to go it stays a bit tacky if you have never used it before just make sure your hands are clean before you touch it during installation it’s best to hang it coat both sides let it hand overnight and install then send it I love these original bikes.
I dropped a tooth on the front sprocket and changed to an aftermarket ignition box at the same time and that was the most noticeable performance change I ever did to my 01 400ex. It is currently an 11:1 426 with a stage 2 cam and sparks exhaust. I lost second gear so its a pending project just like my 250r and kfx450r.
Lightened flywheel is one of the best engine mods you can do on a 400ex. The big bore kits wake them up but a lightened flywheel makes them a lot snappier and they rev a lot quicker. After having one, a normal 400ex feels really sluggish, I’ll never go back to the stock flywheel.
I still can’t believe that was $900. I’m always looking for a deal like that. After the challenge, put some OEM graphics on it. Look forward to seeing more videos of it.
DO THE WHITE BROTHER EXAUST. i have an e series and they are so fun and tunable! apparently the e series was one of the best pipes for that bike when it came out
Dremmel out the welds inside the exhaust headers, take off the air box lid, rejet. This engine is in the same family of the XR250R and XR400R, so there i plenty "free mods" to do.
Awesome man! That's exactly what I did when I got my Banshee last year, I was trying to keep it cheap and low, but as a Banshee; it's a sickness and you always wanna go faster and faster 🤦🏻♂️🤷🏻♂️ so I'm really thinking about the 400ex man! You are doing good man! 👍🏻👍🏻👍🏻
I have also had great luck with the cheap batteries. I agree that a lot of the mods you mentioned should be considered free like trading pipes, used tires etc. Should run a non o ring chain on that thing anyways. Frees up 1-2HP.
Lol had a friend I told specifically not to take my trx 90 in the river. Guess where it ended up? Ended up having to drain the air box of all the water lol. Had to clean the carburetor and the air filter to get it right. Thankfully the engine held together.
For performance the absolute best thing you can do for quick power would be an exhaust. I ran a fmf on a stock engine with a 150 main and 40 pilot and it was super fast. That quad is now built to hell though
Do it up man; beware though, these are super cheap parts I ordered; if you have a bigger budget, I would maybe get better parts. It is possible they will be fine though.
Thats a cool cheap project its nice check the swing arm axl carer bearing see if its dry from water n mud. That also puts a drag on rolling. And thay r $10.00 . stiil in budget. Good job.
@@MichaelSabo ya I run the amazon cheap fat bars, jfg chain slider, $20 rotors, $14.99 brake pads. I think that’s it right now but I will say I did order some cheap grips too ones that’s were pro taper look alike and ended up not using them after installing one cause they were both the same size not one for throttle one of bars and they were really short like noticeably shorter like only fit my hand and it was touching both ends of the grips lol. So let us know how those ones work out
Check out the 440 big bore kit with a 12.5:1 piston, hot cam and bottom end kit (after this series of course). I think the run around 700. Also, check out the auxiliary oil cooler mods ppl have done. There’s vids of that on TH-cam
The new starts are fucking awesome u got me lmfao good stuff🤙 cant wait to see what u do to the 400, I've been wanting to go to a 426 just been procrastinating on my own stuff ur gonna inspire me to go ahead finally do it, as always love the videos
Great video. Only thing i would have done is spent the remaining $10 or so on getting better quality brake pads and gaskets. Looking forward to the next episode.

That skit was funny, too bad people acually have friends like that though. 🤣
Ik the way he just started running 🤣
Someone I know he had someone crash it Off the side of the mountain
Please more of this quad. And I miss when you used to put the heavy metal in the background haha
Oh man, I do love metal; I might try to incorporate that in some more!
@@MichaelSabo you soooo should

FANTASTIC! Love the cheap stuff!
Gotta love having the friends who race and are constanly changing their tires. haven't ran a new set in years
Fr tires can be expensive

Ah man... it's always sad when a machine goes that's been in the family for a while :(
Dude I can't believe you ended Top quad with Justin thats so fucked up bro
Sadly I'm gone too I ride with my friends or I don't ride at all simple as that. You can sense the jealously in this man

The 400ex is my all-time favorite sport quad! I like mine better than my YFZR!
Please build this up like the 250R in the future!!!
....and then sell it to me :)
Micheal I have used rtv to seal the majority of my 400s engine and it’s held up for 9 years plus the time it sat when my dad stopped riding and it ran like a champ and still hasn’t blown
Damn mike , satisfying to watch you work on quads/small engines your a natural mechanic! You got me wanting to hunt down a cheap budget quad!
Thanks so much for the compliment Chad!
First 25 seconds im already laughing while by myself out loud thats how you know its going to be a good video.... great content:)
Haha, thank you so much, I'm glad you like the skits!
This Honda for 900$ is like a gold found in the garage :)
I agree man!
Mann...Mike Sabo is building something that I can "just about" afford...Definitely ...im in.
Dude I just got a 2003 yz125, and now Sabo is doing a build on a yz125! Let's gooo!!!
What's up with the beef with Justin, he just posted on his page. Y'all gotta work together on this you both are why I'm here.
I like sabos content, but if jst bent over backwards for sabo and got treated like dirt in return its best he stays away
@@GBDunknRollCD I get it, I just don't get people sometimes, especially so called friends that do you dirty.
Yeah sabo is just in it for himself.. this dude needs to grow up

I'm leaving sabo channel not cool roids rage

If ur gonna do a 416 kit you might as well do a 440 kit but just a recommendation.keep up the good work💯💯
I've had one of these for the past 4 years and they are TANKS. I'm selling it soon to get a trx250r though! thanks for the inspiration on that one.
100% man! Good luck with your 250 when you get it!
Do you already know where you’ll get the 250r from or you gotta find one?

When he started running I choked on my coke and nearly died 🤣😂
It was the laugh at the end of the skit that got me.
Just the way he came back dirty sxs an truck they gotta be low on gas
I really wish I could find a quad like that
Cant wait for the finishing product it’s gonna be sick!!!🙌🏼🔥💪🏽
That brand of battery you purchased is actually pretty good, I run them in all of my bikes and have had no problems, if you keep them on a trickle charger when not in use for a long period of time they actually stay and hold charges for quite a while.

Full Curtis pipe would be SICK!
DO THE WHITE BROTHER EXAUST. i have an e series and they are so fun and tunable! apparently the e series was one of the best pipes for that bike when it came out
Loved mine for my old 300ex
I doubt they are the best anymore
I love how he took the inspiration from demo ranch on the hilarious intros these are easily both my favorite you tubers

nice find. picked one up for 1800$ really nice shape!
I have also had great luck with the cheap batteries. I agree that a lot of the mods you mentioned should be considered free like trading pipes, used tires etc. Should run a non o ring chain on that thing anyways. Frees up 1-2HP.

Can’t beat the 400s u got a steal !! I say the same thing when my gas is out and someone barrows my truck 😂😂keep up the awesome work !!
You have the best "bike life" content on TH-cam bro love the videos keep it up👍💯
Bro, thank you so much for saying that!
@@MichaelSabo yeah man I mean that you post the best stuff
Very cool you gotta keep it man! I love the bike don't sell it man that's a mean clean 400ex
I swear the skits are the best part of the videos lol.
Lol! Thank you bro! 🤘
love these little cheap builds like this . not everything has to be a full blown race bike to have fun with
Loving the skits, you are a natural.
Edit: I do not think anyone would hold it against you to have the frame sandblasted and painted.
Haha, thank you man! Yea the frame is definitely due to be redone; no doubt.
I have the same one. I paid more. You lucky...,,... but they are kick-ass 😎
I'm "that guy".
Back in my 400ex days. I'd buy the cheapest ebay parts. Everything seems to work fine.
Took a screenshot at 1:35... it is now my wallpaper
You need to do above and beyond billed for that 400ex
When you do the big bore kit don't cheap out on the head studs and head gasket. Header wrap isnt a bad idea either on these bikes.
Cant wait to see the Top Quad series.
I love those funny skits mike!! Order up some jets if you get that pipe also. It WILL need it for the extra power
Hell yeah Mike! Im gonna buy all the parts you bought, for my quad
Do it up man; beware though, these are super cheap parts I ordered; if you have a bigger budget, I would maybe get better parts. It is possible they will be fine though.
Notifications ✅
Can’t wait to see the video !! 😁
I bet it will be great as always! 🤟🤟👊
Jake Harris thank you for watching! 🤘
Love your videos Mike. I'm always looking fwd to see each new video. Keep them coming brother.
Brother, your skits are hilarious. I was laughing when your twin was running away after abusing your truck and leaving you on Empty....lol
Intro was great. Thanks for that.
The skits are funny af!😂
Lol, thank you Dave
@@MichaelSabo 🤘
sicknesss looking good so far. but on the next upgrade stage ill say again. DIFFERENT FOOT PEGS lol
I agree man; maybe some pro peg nerfs!
Thats a cool cheap project its nice check the swing arm axl carer bearing see if its dry from water n mud. That also puts a drag on rolling. And thay r $10.00 . stiil in budget. Good job.
Good call man; its wild how cheap parts are for this thing!
Them 400ex ‘s are scary reliable
Best Intro yet. I can relate.
"dude this is probably one of the strongest chains in the world"
best part of the video lol
The ultimate cheap build, this is great content!!
Love the intro skit. Very funny. Keep it up.
Thank you Danny Armstrong!
I think I wanna come buy it when you’re done with it
Dave Moore is working on my trx 250r motor right now
Dude I tell you what I am a missionary on a budget and I buy a ton of cheap parts on Amazon and eBay and have had no issues what so ever with them yet
This makes me happy honestly lol; it's amazing how some of these super cheap parts can actually be good.
@@MichaelSabo ya I run the amazon cheap fat bars, jfg chain slider, $20 rotors, $14.99 brake pads. I think that’s it right now but I will say I did order some cheap grips too ones that’s were pro taper look alike and ended up not using them after installing one cause they were both the same size not one for throttle one of bars and they were really short like noticeably shorter like only fit my hand and it was touching both ends of the grips lol. So let us know how those ones work out
Check out the 440 big bore kit with a 12.5:1 piston, hot cam and bottom end kit (after this series of course). I think the run around 700. Also, check out the auxiliary oil cooler mods ppl have done. There’s vids of that on TH-cam
Don't forget to remove the air box lid and rejet the carb when you're done, and don't forget the cost of the jets.
Those factory tires on the rear of the 400ex are great tires I’d keep them on it they get great grip but break loose on slides and turns
Sabo you the mother in man .keep up the good work
Please do an oem build on the 400 with mild bolt on upgrades exhaust intake and jet kit
Bro whatever you do be super careful with them headstuds going back in. The valve cover bolts strip so
Easy
Thank you for the heads up man!
@@MichaelSabo no problem if you need valve seals or some gaskets let me know
I’m new but went back I watched most your videos. Love the cheap budget build. Do you think you could do a full build on a 400ex next?
Love the 400 ex I always wanted a nice 400 ex
The new starts are fucking awesome u got me lmfao good stuff🤙 cant wait to see what u do to the 400, I've been wanting to go to a 426 just been procrastinating on my own stuff ur gonna inspire me to go ahead finally do it, as always love the videos
Haha, thank you bro! Yea dude the 416 and 426 are great in my opinion, you should do it up!
Matt from demolition ranch does these kinds skits hilarious.....
YES! Dude Matt inspired me; love his skits!
I wanna see this thing cleaned up with some SC1 shine on it. I guarantee it would look like it came off the showroom.
Great video. Only thing i would have done is spent the remaining $10 or so on getting better quality brake pads and gaskets. Looking forward to the next episode.
