Yeah man! Check the carrier bearings, swing arm bearings, and a-arm bearings. I promise you they’re shot: they all are. Have fun with it, though man, you got a great deal.
I love the MSR fuel tank setup. I'm going to set my 400ex up for cruising trails as well. My friends all have 4x4 quads and we are all middle aged lol.
This 400 is awesome!!! I'm nearly done with the same type of "restoration" on my 2000 and you've given me a bunch of new, great ideas that involve ingenuity~ not relying on dumping a ton of money into it but being practical. I wish I had stumbled across this video sooner. Thank you!
Mine is an 03. Had it for about 10 years now and purrs and pulls like a champ. Love all the mods you did in which I will be copying some of them goodies onto mine.
That’s a clean 400ex man I have the same year with a big bore 440 kit with a stage 2 cam and it runs lean and mean and now I’m trying to get it to look as good as you’d man
Great looking quad bro I love when people put time and effort into what they have, instead of just buying a brand new 450. I myself have a souped up 300ex that I absolutely love she still runs like a beast :) keep up the good work that thing is bad ass.
Sooo sick! I got a 03/04 400ex also that I got on a trade for an old gy6 Carter Talon 150cc kart that I got for $150. The kid that I made the trade with only cared that the kart ran. The quad does need a lot of TLC but I'm very handy and got it running no problem, just need the plastics to get it going on looking this good.
Damn brother.....speachless!!! nice build man!! Love it!!! Middle class man on a middle class budget! I'm a heavy equipment operator making just enough to get by and pay my mortgage,but always enough for toys...Raptor/Banshee build coming soon!!
@Probably wont die from coronavibrus, Funny that you would leave us a comment this mindless; give yourself a thumbs-up; then actually leave the misspelled and half-witted comment up as a testament to your complete lack of education and wit. In all seriousness, it demonstrates great self-awareness that you’ve changed your name from “shit diaper” to “probably wont die from coronavibrus”. You and your outbursts of misspelled rants are always welcomed on our page, sir, for the sake of a quick laugh at your expense, and perhaps a little of our own. 😉
Awesome 400 ex!! I still have 2 2000 models layed out with 460 stroker motors in them and ride with the 450s every weekend.We do some gncc vet C for fun too.great looking quad again..
81 caution have a look at my most recent video of this 400ex. As of today, I have almost $14000 into it. I’m building a second one too, but am keeping it under wraps till it’s completed.
@@swampgumpharpy7977 I found a 99 400EX at a garage sale in my neighborhood and got it for a hundred eighty dollars not running. I cleaned out and rebuilt carburetor and it started right up. Now just looking for ideas. Good luck thanks for sharing
That clear coat is probably "Clear Max 2k" it says 368 0061 in big numbers on the front and it has the plastic thing on the cap you put on the bottom of the can and smack down to break open the hardener chamber inside the can. I bought some at NAPA and its bad ass. Thats a nive 400ex man. I am leaning towards getting one as i see them cheap around here and i have an old honda CM450e twin streetbike sitting here lol it'd be a beast
Best investment on a TRX is the case saver around the lower sprocket. I bought an excellent condition 300ex and continued to ride it like a hooligan the first time out as all young males do and chain fell off because the rear sprocket was worn and chain blew out the lower case. Talk about flushing $2500 down the tube over a $15 ebay part
I love these quads, I've rode them and owned them. If you decide not to put skid pans across the whole quad out at least suggest putting one on your rear swing arm especially for when you go to the trails, you'll be bashing your Sprocket and your disc brake, and keep an eye on the bearing carrier as well, 👌 ;) she's a beautiful build man
So awesome. I just got one, totally dinged up and treated like the tank that it is, I'm looking forward to putting some work like you have into mine. Thanks for giving me hope😂👌🙌
Very nice built. I'm building a 2007 400ex and I'm wanting the red black beadlocks like that? What size is ur front and rear wheels/tires. I can only find rears. Also the blue wire cover from ur rear brake lines up where did u find that?
I want to add that the 400ex or 400x is absolutely the best ATV if you don't want the fastest quad but a fast quad that is super reliable and fun. Best option if you have three grand or less. I live in Michigan and when I go up to the dunes half of what you see you up there are Hondas like this some of them even have big bore kits and Run with the 450s no problem. Half the time it's hard to even tell the difference because they have extended rear axles and extended a arms. You have to look at the plastics and headlight to determine what model it is
Blake Mirsberger I call major bullshit on this one man. With every Honda I've ever owned or been around, if it'll turn over, it'll run! May have burnt valves, worn rings, or what have you, but by god it still runs!
Beautiful Quad man! I've been wanting to get into fixing up old Dirt Bikes and Quads and then Reselling them, All for fun and as side work from my regular 9-5 ya kno. Awsome work tho man!
do you have any pics of how you wired everything when you put the battery box on? Also, on the cmf air scoops. Doesn't that bolt hole go to the flare thats missing on your bike? I thought they just go right in without any modification. you have another hole you drilled through the flare to bolt the scoop on. just curious after watching this video i went and bought some but they don't look like they bolt straight on. did you have to do any shaving to get the top mount to screw on? Thanks and awesome build man!
Nice build, and bravo on completing it in the $3k range. I have two 400EX's and I'm contemplating a complete rebuild on one - parts are expensive! Can you please send me a link to the MSR fuel bottle holders, I can't seem to locate the correct 'topeak' holder. Thank you!
Parts are certainly expensive. I had to reel myself in a time or two. I can't provide a link, but I bought the bottle holders on Amazon. Search for Topeak Modula Java Bottle Cage. Mine have held up great!
I have to ask what is that plastic like material on the brake line going to the rear caliper?? And where I can get that from bc somthing little like that makes the quad look really nice. Thank you in advance
Hey man this is definitely one of the cleanest 400 builds on the youtubes do you have a before and after pic thread anywhere or some place you could post a few pics of the top of the air/battery box with the seat off. I'm in the process of a frame up 400 resto myself and am leaning towards that super clean look getting everything off the frame, but i can't seem to find any decent detail pics of the installed airbox. FANTASTIC WORK DUDE!!
I do happen to have a before and after. As for the inside of the box, no pics, and the 4wheeler is away for a complete top and bottom end rebuild. Those guys move slowly, but I'll take some shots when it gets back. Do you wanna shoot me your email?
Nice build man. I'm about to buy an 01' from my fathers hunting buddy for $1,300. The guy has owned it since new and has only rode it a few times a year since he bought it. It's like a brand new quad. Needs nothing. Sorry, didn't mean to make you jelly.
That sounds great! If it were me, I'd probably still replace all fuel lines, install an inline fuel filter, and flush the fuel tank. Sitting idle is hard on fuel lines.
So I'm a little late but I recently got a 400ex and the oil tank is so close to the exhaust that it already blew the pistons once, do you have a recommendation on what to do becasue I see you didnt move your?
Hey great build but a few questions one what size tires did you get and where did you get them. Third on the alba racing sight was thoes wheels under the Honda trx 400 ex section
Awesome build. I just picked up a 05 yesterday and your build is giving me great ideas. What's the blue covering I see on the swing arm and around the left side of the engine? Thanks
Dig it. So you stayed with original card, just had it rebuilt? Mine is 2009. I been wondering if i should buy new or rebuild. If money not an option would you still rebuild by your mechanic? Thx
This is a good question. As of today, this motor is at CT Racing in Cali for its first rebuild by them, but 5th rebuild overall in 4 years. I wouldn’t trust anybody but CT Racing moving forward (look at some of their videos and reviews). After everything I’ve spent just on pointless engine rebuilds by even highly reputable shops, I would look for new or just start with CT Racing. Clearly, so much more to say on this. Before you decide, watch the Teixeira/CT Racing video posted on TH-cam, and call the man at CT Racing to pick his brain. I will never again trust any “local” mechanic or even the most reputable local race quad builder with my builds.
I seen in a few other comments that you that are in Northwest Arkansas. I live in Northwest Arkansas. I got a 04 400ex, we should hit the trails sometime. I'd love to see your 400ex in person, it's a very nice 4wheeler.
So I’m doing a similar build on my kfx400 and I currently have it stripped down to the frame. when you painted your plastics, (not the bed liner part) did you just sand it down, prime it with the self etching primer, spray a couple of coats of the Rust-Oleum paint on it, then put the usc spray max 2k clear coat over it? I’m painting the plastics on it and I just want to make sure I get everything right that way like you said the gas won’t damage the paint if you spill some on it. Thanks
It’s going to be difficult to find the CARC without going through an industrial coatings rep. A typical paint store won’t have it, and won’t know what it is. I used the etching primer as a base coat against the bare steel of the frame. If I were you I would forego the CARC and use a gloss polysiloxane (like PSX 700 from PPG) over my etching primer. For real, that is a paint that will take an absolute beating. Keep in mind that it’s bloody expensive, and it doesn’t come in anything smaller than a gallon. Don’t use the self-etching primer on your plastics; use a primer that is specifically for plastic. The self etching primer is a two-part epoxy, and it will dry brittle, and crack off your plastics when they flex. Sand the plastics, prime with plastic specific primer, paint with rustoleum enamel, then the clear.
Tank Man sorry for all the questions lol. But did you use the Rustoleum high performance enamel spray paint for this. I just want to make sure I used the same paints, primers and clears you did, on my quad plastics because it seemed to work and hold up for you. Thanks
Hey I wanted to know the name of the “air cals” you talked about. They are the plates and have “RPO powersports HMF” on both sides right underneath the front fenders
Looks great, besides the tank & sides, are you going to re do it? That's gotta be kiln u inside knowing that the quad is 98% finished. Thanks for posting 👍
Tommy 1 C. Are you talking about the plastics? Nah, it doesn’t get to me. The larger point of the build was to keep cost reigned in, so working with the existing plastics was an obvious choice.
Did you have to drill a hole through the rear frame to mount the CFM air box? I just bought one and it says no mods required... But that doesn't seem true
Impressive. I just bought a clean TRX 400ex and the PowerCore muffler is so loud I cant ride it near people. Im trying to find out what I can do to quiet it so I can ride it more places. Any Ideas? Thanks!
KC Troyer Mine’s pretty loud... like, you can hear it around the block at an idle, but it’s deep, smooth, and satisfying. That muffler on yours isn’t cheap, so I bet you’re not wanting to swap it out. If it has a few years on the muffler, I’d try a new packing kit (like $10-$20). Did you already check to make sure the headers are seated properly? No leaks?
Thank you I will repack it. I dont mind replacing it with a stock muffler. I would be happy to do an equal swap for it. It is in great shape and I have not tested for leaks. I could look on youtube for how to do that.
Wow, your attention to detail is very impressive. Beautiful looking machine. Do you live near the Twin Cities in Minnesota? If so, I would like to be your understudy!
CFM Performance claims a 5-degree decrease in temps evident in their test results. The oil cooler shows a decrease in operating temperature of around 20 degrees. I believe that, with the use of the shrouds, oversize oil cooler, and wrapping the headers, I'm probably running around 30 degrees cooler. This estimation is based entirely off of somebody else's test results, and not my own. Thanks for having a look and commenting.
Awesome ride man. Two questions... where did you find those shock covers and where do you find that high temp tape covering the header. Thanks man, love the build!
Hey man! Thanks! I found the shock covers on eBay, and the tape can be purchased at any auto parts store. Most of the major chain parts stores keep this tape in stock. The ebay seller is jorpi-bike. These socks are far superior in quality to any others I've used.
I used my phone without an auxiliary mic. To answer your question below, the Hercules liner has held up flawlessly. One concern I had was that it would add too much weight to the fenders, and cause them to break off; however, that hasn't been the case.
hey man nice quad keep it save , I wanna ask you about dyno jet for ex400 what do u think about it if it gd or not ? and what the dyno jet will do for ex400 ?
Don't they make a programmer? It seems like I remember that they make a few performance parts, and I had looked into their programmer. I can't remember what made me lose interest, but I never got one. What are you hoping to achieve with it?
Aqeel Khalaf I jetted my 2013 400x, put a k&n intake and power lid on, and added a slip on fmf powercore4. I had serious doubts of true performance changes. Maintaining objectiveness when I ride my unmodded new 2014 400x I absolutely prefer the 2013. It has smoothed out so much and all that feeling of restrictedness is gone. The response is night and day. 49 bucks for the kit, 111 for the kid, 59 for the filter. And 150ish I believe for the slip on, and an hour maintenance at the shop for tuning. Frickin worth it. I'll post a side by side soon.
Aqeel Khalaf I have never modded a power sport engine, just Gm crate motors. With that as my baseline experience I will say you really have to have a solid future goal in mind. If you're just trying to beat your neighbor and get bragging rights I highly suggest not touching the internals. Honda hasn't in years for good reason, these high rev motors just last so long and are that reliable. Now, if you feel you're just not getting the little bit of umph you need to tackle your favorite hills and dunes you might try modifying your air flow first like I stated above. If you're still not there, change your sprocket out and gain some torque. Rarely we need to go 45-50 on these anyway with such a spongey suspension. If, you still need more get a hot cam and port the heads, and get stronger head bolts for the increased compression and a high performance head gasket. After that I'm out of my element and don't want to make recommendations past that. But give the easy stuff a try first. You might be highly satisfied. And if you're a bigger guy like me, widen your wheels. It will make a difference as well. Unless you really doin right trail riding then disregard. Hope that helps
Chris Huber I painted the engine with caliper paint from Rustoleum, then I used those Dremel abrasive buffs to polish the edges of the cylinder head fins.
I know I’m 3 years late ,but I have a 2001 400EX what would you recommend upgrading on it first it’s stock ,besides the brand exhaust,and what suspension would you recommend,I’m 6,1 and about 132lbf
ClashOfDragons have a look at my updated video on this EX. Just posted last week. My first upgrade would be new wiring harness. If it has any original wires, or looks like anybody has messed with wiring, have an all new harness installed. This is the best upgrade you can do on an old quad.
That is probably one of the best looking 400ex's I've ever seen I hope you do more videos man 👍👌

That's blue, plastic conduit. I took mine off because, although it looks good in pictures, it looks a little cheap in person. That's just my opinion.
Dig it. So you stayed with original card, just had it rebuilt? Mine is 2009. I been wondering if i should buy new or rebuild. If money not an option would you still rebuild by your mechanic? Thx
This is a good question. As of today, this motor is at CT Racing in Cali for its first rebuild by them, but 5th rebuild overall in 4 years. I wouldn’t trust anybody but CT Racing moving forward (look at some of their videos and reviews). After everything I’ve spent just on pointless engine rebuilds by even highly reputable shops, I would look for new or just start with CT Racing. Clearly, so much more to say on this. Before you decide, watch the Teixeira/CT Racing video posted on TH-cam, and call the man at CT Racing to pick his brain. I will never again trust any “local” mechanic or even the most reputable local race quad builder with my builds.
Did you get rid of the white brothers exhaust? Would you mind giving it to me perhaps.
I seen in a few other comments that you that are in Northwest Arkansas. I live in Northwest Arkansas. I got a 04 400ex, we should hit the trails sometime. I'd love to see your 400ex in person, it's a very nice 4wheeler.
Let's do that! My email is ngray@ tankspek . com
So I’m doing a similar build on my kfx400 and I currently have it stripped down to the frame. when you painted your plastics, (not the bed liner part) did you just sand it down, prime it with the self etching primer, spray a couple of coats of the Rust-Oleum paint on it, then put the usc spray max 2k clear coat over it? I’m painting the plastics on it and I just want to make sure I get everything right that way like you said the gas won’t damage the paint if you spill some on it. Thanks
It’s going to be difficult to find the CARC without going through an industrial coatings rep. A typical paint store won’t have it, and won’t know what it is. I used the etching primer as a base coat against the bare steel of the frame. If I were you I would forego the CARC and use a gloss polysiloxane (like PSX 700 from PPG) over my etching primer. For real, that is a paint that will take an absolute beating. Keep in mind that it’s bloody expensive, and it doesn’t come in anything smaller than a gallon. Don’t use the self-etching primer on your plastics; use a primer that is specifically for plastic. The self etching primer is a two-part epoxy, and it will dry brittle, and crack off your plastics when they flex. Sand the plastics, prime with plastic specific primer, paint with rustoleum enamel, then the clear.
Thanks for the reply. And just making sure, you used the USC Spraymax 2k high gloss clear on the shiny part of the plastics correct?
Tank Man sorry for all the questions lol. But did you use the Rustoleum high performance enamel spray paint for this. I just want to make sure I used the same paints, primers and clears you did, on my quad plastics because it seemed to work and hold up for you. Thanks
nice build man
Good job 🔥🔥🔥
Hey I wanted to know the name of the “air cals” you talked about. They are the plates and have “RPO powersports HMF” on both sides right underneath the front fenders
Maybe I missed it but how and what did you use to paint the motor and what did you use to keep the engine from chipping the paint or making it faded?
I have a new video coming out in a couple of weeks. I'll discuss painting the engine in that video.
great build
Hey man what bolt pattern did u go with on the wheels? Also tires size and choice I like the look of these!
yeah it's kinda difficult my 400ex looks amazing. lol nice quad man
Nice 👍 good job 👍 get in the motor now😬
On that, Hoss. Look at new vids for updates. 😄
Were to buy the "air/wind callers"?
Looks great, besides the tank & sides, are you going to re do it? That's gotta be kiln u inside knowing that the quad is 98% finished. Thanks for posting 👍
Tommy 1 C. Are you talking about the plastics? Nah, it doesn’t get to me. The larger point of the build was to keep cost reigned in, so working with the existing plastics was an obvious choice.
Did you have to drill a hole through the rear frame to mount the CFM air box? I just bought one and it says no mods required... But that doesn't seem true
Jonathan Presseller, Mine fit without any modifications or drilling.
Impressive. I just bought a clean TRX 400ex and the PowerCore muffler is so loud I cant ride it near people. Im trying to find out what I can do to quiet it so I can ride it more places. Any Ideas? Thanks!
KC Troyer Mine’s pretty loud... like, you can hear it around the block at an idle, but it’s deep, smooth, and satisfying. That muffler on yours isn’t cheap, so I bet you’re not wanting to swap it out. If it has a few years on the muffler, I’d try a new packing kit (like $10-$20). Did you already check to make sure the headers are seated properly? No leaks?
Thank you I will repack it. I dont mind replacing it with a stock muffler. I would be happy to do an equal swap for it. It is in great shape and I have not tested for leaks. I could look on youtube for how to do that.
KC Troyer You might check to see if you can find a quiet core for the FMF muffler that’s on it now. I’ve heard tell they make those.
Cool. I will check. Thank you
Where would you recommend getting atv’s like the 400ex from ?
Craigslist, Facebook Market Place
beautiful 400ex!
I got a 400ex from my uncle for 100$ but I need to fully rebuild it so thanks for an idea on how I could do it
Wow, your attention to detail is very impressive. Beautiful looking machine. Do you live near the Twin Cities in Minnesota? If so, I would like to be your understudy!
Arkansas, actually. And thanks!
Really nice build. Great job. I have an '07 that I am thinking of doing some mods to. How much cooler does that air shroud keep the bike?
CFM Performance claims a 5-degree decrease in temps evident in their test results. The oil cooler shows a decrease in operating temperature of around 20 degrees. I believe that, with the use of the shrouds, oversize oil cooler, and wrapping the headers, I'm probably running around 30 degrees cooler. This estimation is based entirely off of somebody else's test results, and not my own. Thanks for having a look and commenting.
Nice quad. Where u get that air/battery box? 👍
I’ve seen them on eBay before, I think they were around $100, but check eBay man! Good luck!
Awesome ride man. Two questions... where did you find those shock covers and where do you find that high temp tape covering the header. Thanks man, love the build!
Hey man! Thanks! I found the shock covers on eBay, and the tape can be purchased at any auto parts store. Most of the major chain parts stores keep this tape in stock.
The ebay seller is jorpi-bike. These socks are far superior in quality to any others I've used.
so sick im gonna do something like this to my 400ex
nice job. looks really good.
Nice bike man. Would you happen to have the dimensions for that air box? I want to fab one. Just can't bring myself to pay $120 for it.
watch camera and settings did you use for this? And did use a mic? I'm not like some of the videos ive made with gopro and rode mic
I used my phone without an auxiliary mic. To answer your question below, the Hercules liner has held up flawlessly. One concern I had was that it would add too much weight to the fenders, and cause them to break off; however, that hasn't been the case.
Thanks for the fast response. I have 2 red ones, i want to break up the red a bit.
hey man nice quad keep it save , I wanna ask you about dyno jet for ex400 what do u think about it if it gd or not ? and what the dyno jet will do for ex400 ?
Don't they make a programmer? It seems like I remember that they make a few performance parts, and I had looked into their programmer. I can't remember what made me lose interest, but I never got one. What are you hoping to achieve with it?
Aqeel Khalaf I jetted my 2013 400x, put a k&n intake and power lid on, and added a slip on fmf powercore4. I had serious doubts of true performance changes. Maintaining objectiveness when I ride my unmodded new 2014 400x I absolutely prefer the 2013. It has smoothed out so much and all that feeling of restrictedness is gone. The response is night and day. 49 bucks for the kit, 111 for the kid, 59 for the filter. And 150ish I believe for the slip on, and an hour maintenance at the shop for tuning. Frickin worth it. I'll post a side by side soon.
Thank u so much , what do u think about to upgrade the ingine ? Whats ur advice for engine what to put ?
Aqeel Khalaf I have never modded a power sport engine, just Gm crate motors. With that as my baseline experience I will say you really have to have a solid future goal in mind. If you're just trying to beat your neighbor and get bragging rights I highly suggest not touching the internals. Honda hasn't in years for good reason, these high rev motors just last so long and are that reliable. Now, if you feel you're just not getting the little bit of umph you need to tackle your favorite hills and dunes you might try modifying your air flow first like I stated above. If you're still not there, change your sprocket out and gain some torque. Rarely we need to go 45-50 on these anyway with such a spongey suspension. If, you still need more get a hot cam and port the heads, and get stronger head bolts for the increased compression and a high performance head gasket. After that I'm out of my element and don't want to make recommendations past that. But give the easy stuff a try first. You might be highly satisfied. And if you're a bigger guy like me, widen your wheels. It will make a difference as well. Unless you really doin right trail riding then disregard. Hope that helps
Looks great!! Did you paint the cylinder housing/top end black or did it come like that? If so what paint did you use the CARC or the Rustoleum?
Chris Huber I painted the engine with caliper paint from Rustoleum, then I used those Dremel abrasive buffs to polish the edges of the cylinder head fins.
@Swamp Gump Harpy what a great idea on the engine paint. How is the caliper paint on the engine and the Hercules coating on the plastics holding up?
Wow that wiggling is trippy
Chris VFX It is. In my defense, I was experimenting, and had no clue that this silly video would get more than fifteen or twenty views.
@@swampgumpharpy7977 haha anyways it was a good video!
That look so sick
I know I’m 3 years late ,but I have a 2001 400EX what would you recommend upgrading on it first it’s stock ,besides the brand exhaust,and what suspension would you recommend,I’m 6,1 and about 132lbf
ClashOfDragons have a look at my updated video on this EX. Just posted last week. My first upgrade would be new wiring harness. If it has any original wires, or looks like anybody has messed with wiring, have an all new harness installed. This is the best upgrade you can do on an old quad.
