2001 XR400R here , freshened up top end, Hot Cams stage 1, opened up exhaust, pumper carb.... I tightened up the valves a tiny bit more than Hot Cams wanted. I put them between the stock setting and the stage one settings. Makes way less noise. Its a fun bike. Makes quite a difference on mid/top end. I tend to run it a little in the rich side too. Not much, but a little on the safe side. Cant wait for warmer weather!
The 426"88mm' piston with Stage 2 Hot Cam is a blast to ride in the mountains. Has lots of low end and go power delivery at high speed. That's what I have. The Powerbomb header also on it and it really makes it a great woods machine. Really enjoy your videos! Keep up the good work!
A tip for removing the small 8mm bolts with less breakage: Take a hammer and punch, give the bolts a few good hard sharp hits, square on the head of the bolt. Before you begin, spray all the heads with penetrating oil. It won't get down to the threads, but it will work between the bolt head and rocker cover. Just try it. It works.
I have had two 416 builds A 10:8 comp piston from JE with a stage two hot cam it was just an animal of a machine dropped a valve and slightly bent the rod (I didn’t notice it) flushed bottom end of chunks checked everything over all looked acceptable to just be a top end rebuild so I rebuilt it. Put a 11:1 Wiseco 416 piston and jug new head new valves new valve cover everything installed by the manual road it maybe 3-5 times after breaking it in went out riding with my buddies one weekend and it snapped/broke the rod and sent it through the cases blowing the starter off never seen anything like it with the 400ex. It makes me happy to see another 416 living
I installed a few of these HotCams... Without the proper piston and jetting they are hardly noticeable... WebCams got a little more hit to them. The lobes let in more gas and you can hear the chop like if it was a high powered race car !
It's called duration. That's where the lope comes from at idle and higher duration equals more top end power. This cam is obviously a pure mid range cam. Nothing wild!
With all the upgrades, especially the front suspension because everyone knows that's the weak link on 400ex's. It's probably comparable to a trx450r or very close anyways, but way less fatiguing to ride. Good job Joe! Added comment...you now have property to build a legal top speed run test site. Make it happen when everything else is built.
Just a tip, when wheeling pop the clutch so your not redlining to get it up and coast in that balance point and work on your break control in case you go too far back
My 2001 trx 416ex has the old stage2 hotcan. Now known as stage 3. That and my Ross 416 piston made that ex a rear ripper. I widened mine out to 49 inches wide front and rear. Im running stabdard length shocks front and rear with chrome aarms as well as chrome axle. This think handles like its on rails. I also have a 2004 trx450r with hrc cam and widened out to 50 inches front and rear. The 450s power is unmatchable by the 400ex motor. But in my opinion the 416ex outhandles the 400.
Use of a true assembly luke such as gel lube or a moly paste on the new cam lobes would have been a better choice than the thin oil used for this install. Cam lobe wear and rocker wear on initial start up can be severe with improper lubrication.
Really love the vids and this is the first video where ive seen you actually put a peformance part on something instead of restoring. Keep up the good work!
Now this was a really good video informative- riding- and great all around up grade you should do more videos like this ... I hope you can get a ltr450 soon cause I think alot of people will want to see that and also I think you will love the way they handle also.do more ride reviews of what you like and dislike after each project I think that would be a great end to each of your videos
IDC what anyone says man that valve train noise is not normal, don't use hotcams specs. I have a hotcam & wiseco 416 with la sleeve & ported head. I use to use stock specs with mine & it sounded like the factory level of valvetrain noise but you can play with the clearances a little & get it really quiet. You can not hear the valve train over the exhaust on mine at all. Iirc I think the specs I'm using now are .03 tight & .03 loose, & this thing is an animal.
This was awesome buddy...I love this channel and the content...this was a great video for people that don't know a lot...you really went into great detail on this one...awesome job brother...keep the videos coming...
I put one of these cams in my 400EX. I like it. Some people say they have seen them wear out like the metal is soft. I sent mine out to have it cryohardend before I installed it.
As much as I don't care for 4-wheelers (I've seen too many serious accidents with them by ameteur riders and one death) I have to admit that the engine sounds absolutely strong. I put a White Bros all-around cam in an XR200 years ago + a big bore kit and experienced the same power increase(to a lesser degree with smaller engine)........seems like a VERY good combo for waking up the Hondas. It has run strong for nearly 25 years now with absolutely no complaints. I'd like to see this combo in an XR400. P.S. Same "rattling" with my cam change.......must have aggressive ramps on lobes. For the life of me I do not understand why Honda did not market "Staged cams" that would allow you to dial in more power and still have the factory "blessing". I very much enjoy your uploads, primarily because you do a good step-by-step analysis and then a fix. Also, if your Tacoma gets stuck you can pull it out with the 416ex - LOL. Keep the Faith, Tom
Joe, That Fourtrax is an animal. I'd love to try it out, you ought to get one of your other ATV's and have your brother race you with this monster. I'd bet this is close to a 500 with the big bore kit and the new cam. Bear Claw tires for the rear tires or the old Wooly Booger tires.
Ide like to see some new front and rear wheels. Maybe some bead locks since you'll be riding in the trails. Grip/hand guards for the trail riding. You'll be just about good to go
wow Joe that is a monster, just add two new rear tyres and keep it. Thanks for the awesome content, keep it up. Regards Dave from Port Elizabeth, South Africa
I was curious if you were going to lease the land out to the farmer until the year you were ready to build on the property? If so he may harvest and reseed with another crop right away.
Lower the clip on your needle 1 noch and take your main jet back to a 155. It’s running to rich on the 158 and you can tell just by the way it sounds. I have the 426 high compression piston stage 2 cam and a ported head and it keeps up with a stock 450 with a slip on.
Just bought one of these for 1200 bucks and i love it it has some issues but i think i made out it has a long travel kit new exhaust fox shocks and after watching ur video possibly already a cam so all thats the issue is shes got cosmetic damage
Measuring the overall height of the lobe means nothing without knowing if the base circle of the cam is the same. Valve lift is only part of the equation of cam performance. Lobe separation, lobe center line and duration all factors in as well as other factors.
Cool. It starts up right away, idles perfectly, and revs up to full power with no misfiring. And sounds awesome 👍 PS - Just make sure not to run over the farmer's beans :-)
You should have Bought an 85/86 ATC250R. Now THAT has REAL power. Plus every 4 stroke rider secretly wish they had a TWO STROKE. I still ride my 85 250R monthly.
I rebuild these things constantly for people, my only hope is it has new valves in the head. I have never rebuilt one that the valves didnt have a lip and on the verge of sucking up then dropping. Im editing this now that im further along in the video. When i rebuild these i do new kibblewhite valves and springs, rocker arms and timing chain with the stage 2. never have i had one that sounds like that. But they are fun and hella more power when the new cam is installed
Bro I have a small youtube channel and I built a 426ex with a stage 2 hot cam and I didn't use hot cams recommendations for valve lash and it makes no noise what so ever in the head it's even more quiet than a stock 400ex
I have a 2004 but I didn't go with the Jr I went with wiseco stock piston with jug stage 2 cam stage 2 CDI and a Jr lightens flywheel stage two coil she rips about 90 mile an hour
The way your “measuring” the lobes on the cam is wrong. The aftermarket cam just has different shaped lobes, not usually bigger or measurably longer. aftermarket cams or hot cams work by keeping the valves open for a longer duration, a machine shop can actually grind your stock cams and modify them to have the same lift duration as a stage 2 or 3 cam
Those valve clearances look a little loose. Did you make sure that you couldn't get the next size up in there on the feeler gauge? If not I recommend doing it next time. You should feel a light to moderate drag on the feeler gauge. I couldn't really tell in the video but it almost looked like no drag if not very little.
ltz 400 is another good quad all around and a little faster than a 400ex stock vs stock. The ltz 400 engine is super reliable bomb proof if you keep it stock with no engine work. I had a dvx 400 which is the same as a ltz 400. Never had any problems with it. I also had a lot of 450 atvs and they are not reliable at all if you ride the crap out of them like me. I still have a LTR 450 that is known to be the best handling 450 it rides on rails through the turns. I have went through 4 engines on the LTR 450 lol. All the way from stock to fully built 516 big bore stroker engine. I love 450 quads but they are money pits, id stick with an ltz 400. Built 450 quads can be faster than a stockish 450 dirt bike, which is hard to do as bikes are a lot lighter and less rotating mass.
sweet! personally if you are getting new tires, I would go through the trails and spin tires everywhere.....this will make the trails easier to use. burn them up dude! BTW, check out the latest vid. from grind hard! OMG crazy fast banchie with a honda 600 engine!
Ok, quick question for anyone. My son and I are installing one of these. For those newbies like us, mentioning the existence or lack there of, of the decompression pin and spring would be helpful. My son removed the old cam while I wasn’t around (not knocking his enthusiasm) I’m now not 100% sure there was or wasn’t a decompression pin. Without seeing it for myself. How do I know after the fact there wasn’t a pin and it’s now floating in the bottom of the block somewhere? One, the cam that came out of ours appears to be stock. Two, without modifying the stock came, would the bike even run without the decompression pin? I’m attempting to decide if I need to pull the clutch side case and look.
next port and polish and mill the head for more compression...or just a higher compression piston...or both...def notice a change....ps that slight difference in cam size aint that much of an increase...some yes...but it aint no thumper cam or rv cam haha jk

Sea Foam Deep Creep!!
If there are any bow hunters next door they are going to love you come October. Quad seems solid that would be a keeper.
Deer won’t care… they’ll get used to it.
This quad is actually for sale on market place as we speak lol. If you are in Wisconsin that is.
Who cares what they love it’s his property 🤷
Man fuck them bow hunters they always have something to say about us riding

Really liked the elevated, rear angle hole shot footage you got with the drone. Was the right height for the shot.
Just a tip, when wheeling pop the clutch so your not redlining to get it up and coast in that balance point and work on your break control in case you go too far back

I generally like to open my engine up so I can drop dirt in it as I disassemble all the stuff I didn't clean up first 🤣
0:19 four wheeler
That just goes to show you you don’t have to be anal about everything and it still runs fine afterwards!
Really love the vids and this is the first video where ive seen you actually put a peformance part on something instead of restoring. Keep up the good work!
Now this was a really good video informative- riding- and great all around up grade you should do more videos like this ...

Once again an outstanding video. Keep up having fun with all you do.

I had a 440ex with stage 2 hotcams and it was so fun. You could sit forward on it and just take off and wheelie through all the gears.
I say next you get a bigger carb you could even make this quad like a series of power upgrades and seeing how much more power you can make it get
That's awesome. You took my advice. Great job on the build🔥🔥🔥
Big red!! Ow she runs well now Joe.. Well done sir 👏
As much as I don't care for 4-wheelers (I've seen too many serious accidents with them by ameteur riders and one death) I have to admit that the engine sounds absolutely strong.

Joe, That Fourtrax is an animal. I'd love to try it out, you ought to get one of your other ATV's and have your brother race you with this monster. I'd bet this is close to a 500 with the big bore kit and the new cam. Bear Claw tires for the rear tires or the old Wooly Booger tires.
Congratulations, exciting ride . looking forward to more .
something doesnt sound right when you started it the first time and revved it, when you let go of throttle there is a rattle noise
Ide like to see some new front and rear wheels. Maybe some bead locks since you'll be riding in the trails. Grip/hand guards for the trail riding. You'll be just about good to go
Best running beast I have seen yet on your channel. She will hurt ya if your not careful, that's what makes it soo much fun🤘
Coward
These are all things you are
I bet your own family looks down on you in shame
wow Joe that is a monster, just add two new rear tyres and keep it. Thanks for the awesome content, keep it up. Regards Dave from Port Elizabeth, South Africa
No wayy. Im watching from jeffreys bay
Great video,you must be so happy to be able to test as well as ride on your own property,, tks for taking us along for the ride
Go with a Curtis Sparks 39 or 41 mm FCR Carb set up for the 400EX. You'll love it! Huge Power!
Those hotcams are sweet, but Remember regardless it’s not stock so if you race especially replace that timing chain more often!
450r carb with those mods makes it a complete beast give it a shot its amazing
That cam maybe a honda xr400 cam. Many run those in race bikes.
Nice upgrade!
Should also do a gear swap, rev box, jet the carb, port and polish the heads and air box that ex will come alive big time
Joe to make that cam really work to its full potential port the cylinder head that will flow good
Crazy, always a new video lol. Keep up the grind man
I was curious if you were going to lease the land out to the farmer until the year you were ready to build on the property? If so he may harvest and reseed with another crop right away.
Just imagine how good it will pull with new rubber on the rear.
Cam should be scribed on end or back side of sprocket tab. I have a white brother cam marked stage 2 that way
Cool! Love the upgrade videos as well! The 400ex specialist right here :D
Lower the clip on your needle 1 noch and take your main jet back to a 155. It’s running to rich on the 158 and you can tell just by the way it sounds. I have the 426 high compression piston stage 2 cam and a ported head and it keeps up with a stock 450 with a slip on.
I ran this same setup but 440 big bore just a tip
Check into a cdi box. Especially the xr400 power is there way higher rev limit
Just bought one of these for 1200 bucks and i love it it has some issues but i think i made out it has a long travel kit new exhaust fox shocks and after watching ur video possibly already a cam so all thats the issue is shes got cosmetic damage
Clutch is slipping when load is applied 3rd and 4th gear Gunna need some new clutch plates
Good job just watch the more engine mods you do heat becomes excessive. Buddy of mind chud a 426 years ago and had heating issues
That is a nice 400ex looks pretty clean
Nice ATV! But it needs a built CR500 2 stroke and a slightly extended swing arm! 🤯
Major vibration issues and would likely vibrate half the machine apart. That is half the fun though!
@@27Zangle yup! But you can get rubber engine mounts and vibration dampener handle bars. It would be the coolest 400ex ever though!
Cracking quad joe you've done a great job on it defo a flyer sounds great too take care mate 🔧🔧🔧🔧👍👌

Interesting video really liked this one and that 400 rips pretty good nothing but fun👍🏼👍🏼
New rear tires and she’ll be one heck of a ripper
You should make
A video practicing head porting on the 400ex, I’d use a niche head to practice tho
should customise your own 2vintage graphics kit for it that would be sick you should keep this quad
i love your videos and your progress, keep it up!
You should have Bought an 85/86 ATC250R. Now THAT has REAL power. Plus every 4 stroke rider secretly wish they had a TWO STROKE. I still ride my 85 250R monthly.
Keep it. I Won’t have anything to do with telegram.
I rebuild these things constantly for people, my only hope is it has new valves in the head. I have never rebuilt one that the valves didnt have a lip and on the verge of sucking up then dropping. Im editing this now that im further along in the video. When i rebuild these i do new kibblewhite valves and springs, rocker arms and timing chain with the stage 2. never have i had one that sounds like that. But they are fun and hella more power when the new cam is installed
I just put a cam and big bore on what should the valve clearance be and is ticking normal with the hot cams
shes a beast, those cams are worth the price sometimes
idk why im getting a scam attempt :/, these telegram scammers can get annoying smtimes
thnx for hearting my comment tho!
When I see that joe uploaded I get happy
Nice job brother. Sweet ride before, even sweeter now. Be safe :)
WEEE see Joe go round and round like a ten year old!!!
Nice work, I put a stage 1 in my ltr 450
I saw this on face book after I watched the other video and I live like to towns away for you in shawano
that valve noice🥶
You should try to find a front plastic with the fenders still on it it does look weird with them cut off I also don’t understand why ppl do that
I’d probably go 160 main if airbox lid is on with a 40-42 pilot with those mods.
I gotta be hard reselling a hot Boi. I sounds like it's eating itself
I appreciate the video.
Yeah definitely lean,and some porting will make that cam work better trust me
i'm dying to see the top speed! 🤔🙌🙌
Looks like a lot of fun.
I had a 98 300ex with a dg slip on and it sounded almost identical. Yours is a tad throatier. Those engine most share identical architecture.
That thing fukin rips llo
Sometime in the future you should really soup up a dirt bike or atv.
He must be happy with that cam, alot of Woo-hoo in there 😅
if top end is noisy then its most likely valve bounce and weak valve springs after a cam upgrade
Bro I have a small youtube channel and I built a 426ex with a stage 2 hot cam and I didn't use hot cams recommendations for valve lash and it makes no noise what so ever in the head it's even more quiet than a stock 400ex
I have a 2004 but I didn't go with the Jr I went with wiseco stock piston with jug stage 2 cam stage 2 CDI and a Jr lightens flywheel stage two coil she rips about 90 mile an hour

The aftermarket cam just has different shaped lobes, not usually bigger or measurably longer. aftermarket cams or hot cams work by keeping the valves open for a longer duration, a machine shop can actually grind your stock cams and modify them to have the same lift duration as a stage 2 or 3 cam
Those valve clearances look a little loose. Did you make sure that you couldn't get the next size up in there on the feeler gauge? If not I recommend doing it next time. You should feel a light to moderate drag on the feeler gauge. I couldn't really tell in the video but it almost looked like no drag if not very little.
My papas put a hot cam on his dritbike and he loves it
They stamp the name on the cam there so when you pull the cover you don't have to remove the cam to find the name you can see it through the gear
what do you do for a living to have all those toys
Sparking plug is tan, that is ideal for a 4 stroke!!
Did honda ever put the cr500 engine in a quad ?
Hey I have a question what would you recommend for a sport quad for a $2000 dollar budget
Honda 400ex haha
400ex is a good choice. Alternatively a Yamaha Blaster with some minor upgrades will run with the 400ex.
@@kernelbadness I have a Yamaha blaster with a big bore kit in it but I’m to big for it
@@king_doodle-yt1254 cool. What kit do you have?
ltz 400 is another good quad all around and a little faster than a 400ex stock vs stock. The ltz 400 engine is super reliable bomb proof if you keep it stock with no engine work. I had a dvx 400 which is the same as a ltz 400. Never had any problems with it. I also had a lot of 450 atvs and they are not reliable at all if you ride the crap out of them like me. I still have a LTR 450 that is known to be the best handling 450 it rides on rails through the turns. I have went through 4 engines on the LTR 450 lol. All the way from stock to fully built 516 big bore stroker engine. I love 450 quads but they are money pits, id stick with an ltz 400. Built 450 quads can be faster than a stockish 450 dirt bike, which is hard to do as bikes are a lot lighter and less rotating mass.
sweet! personally if you are getting new tires, I would go through the trails and spin tires everywhere.....this will make the trails easier to use. burn them up dude! BTW, check out the latest vid. from grind hard! OMG crazy fast banchie with a honda 600 engine!
If that’s what hotcams make a 400ex engine sound like, I don’t want one😅
He's got the valve lash WAYYYY too loose!!
Bro how r these quads and bikes so cheap in ny someone thinks a 2007 crf150r is 6k and it’s clapped out bro
seeing s the xr 400 is basically the same engine i might do these mods to mine when she blows up thats when because its a xr bombproof
don't forget to read the plug and confirm new jetting
Ok, quick question for anyone. My son and I are installing one of these. For those newbies like us, mentioning the existence or lack there of, of the decompression pin and spring would be helpful. My son removed the old cam while I wasn’t around (not knocking his enthusiasm) I’m now not 100% sure there was or wasn’t a decompression pin. Without seeing it for myself. How do I know after the fact there wasn’t a pin and it’s now floating in the bottom of the block somewhere? One, the cam that came out of ours appears to be stock. Two, without modifying the stock came, would the bike even run without the decompression pin? I’m attempting to decide if I need to pull the clutch side case and look.
Wow awesome video! 🎉
Also has a 450r timing chain
Absolute beast !
416 plus the stage 2 hot cam will keep up with the 450s
next port and polish and mill the head for more compression...or just a higher compression piston...or both...def notice a change....ps that slight difference in cam size aint that much of an increase...some yes...but it aint no thumper cam or rv cam haha jk
