Honda 400ex Full Throttle (VERY POWERFUL)

I take my 1999 Honda 400ex for a trail ride and then test compression. We need to figure out why it is smoking. #Honda, #400cc, #SmokeyGirl,

Almost guarantee it's valve seals!!the EX'S are one of the most balanced quads EVER I'm 6'4 and have no problems doing one handed wheelies down the whole street!!..they're a really reliable quad as well bro!!

[@jasonbell1698]

every 400ex i’ve owned or been around is very cold natured but that can be fixed! these machines along with many others were jetted very lean from the factory to pass emissions. if you bump the pilot jet up to a 42 it will start up 100x better.

[@clappedtater310]

I can't dig up their lawn, proceeds to slide the back end back and forth when he gets past the puddle

[@sheluv_jax9046]

😂😂 and the tires are so bald

[@2vintageDeamonFan]

I love the sound of this quad

[@wd-40everything65]

I think your on the right path with valve seals judging by compression and the plug didn't appear to be oil soaked. At first I figured it was worn piston and rings and scored cylinder due to the K&N filter (not a good filter for small particulates) and it was not serviced. Glad to see your diving in deeper and attempting to correct these issues! You get 5 squirts 💥💥💥💥💥 of WD-40 for the effort alone!

Omg yes !!! Right on .. short shifter !!!

[@jasonpetrich4141]

He short shifts cuz he is scared of the power band on 2 strokes, he rev bombs the 4 stroke cuz it has no power band, and he is used to that, not sure where he learned how to work on bikes but .. his skill needs work

[@milkbones8617]

Jason Petrich I remember when he got that 93’ kx125 and it was mint asf, just needed everything flushers because it sat for 6 years, when he started it up it was literally running perfect, best two stroke I’ve ever heard on his channel tbh, and what does he say “she’s running lean, might need to fix that” that’s why his shit always blows up, like wtf it was running perfect

[@just_in_time5518]

LOL i was going to say at one point have to hold that throttle in all the way when doing that compression test. 150psi is good! Adjust the valves and see where that gets ya. Great video keep up the hard work :)

[@aidensmith3591]

I had two xr400s same motor as the four wheelers awesome motor damn near indestructible. I think it would be a lot easier for you starting it if you just didn't touch the gas at all because they flood really easy. Mine always started right up without touching the gas

[@jasonpetrich4141]

Word of advice! also put some hard silicone on the plug side of that boot and on the coil side of the plug wire it will make it water tight to keep it running in the wet/water,if the coil gets wet it will shut off till it dry's out, I had a problem with my 01. Trx 300ex coil getting wet and shutting the bike off. Now I can put it in 3 foot of water with no problem, other than air

[@michaelatkins2154]

You should put the oem 400ex spark plug wire it is built differently and it won’t get close the the exhaust.

Well like i said in the first video when you picked up that quad. Valve seals check them before rings. I bet it is Valve seals:) Nice video👍

[@TheJessicarabbit09]

hands down my fav quad!!! really red line those gears, wont hurt her

[@RealSuburbanCowboy]

If you need help with the valve seals, I offer up my help for free. I am guessing you can do it no problem. BTW, when you do compression test, ideally you should be at Wide Open Throttle! 150 is totally fine. You might have piston rings that are not staggered. If I had to guess, I would say valve seals.

[@Ja-fh8io]

I picked up an 87 honda 350d smoked like a 2 stroker but after riding it everyday for a solid 6months didn't do any work and now she doesn't smoke at all sometimes all it needs is to be rode

[@greathornedowl3644]

👏Bravo, you adapt and overcome the stranded situation. 😂The secret is rocking it like a rocking horse. 🤦‍♂How many have rebuilt an engine, bored out the cylinders, but used original gaskets

Nice! Going to watch at lunch time👍

[@leonardobauchiero1347]

For it not starting try taking the gas cap off, sometimes the vacum builds in the tank

[@carterhayes2478]

I think its the valve seals. My ltz 250 did the same thing when I got it but I threw in new rings and it still smoked. I got the seals and that fixed it. So try valve seals.

[@leightonpolk1731]

I have the same quad! Mine smoked at first but an oil change did the trick

[@dakotamckay2504]

U think maybe do some stancy race upgrades ? Axle, a arms, headlocks, tires, big bore kit?

[@playboihunty4431]

Putting on Air Shrouds and Heat wrapping your exhaust helps with 400ex overheating problem

[@jodyhakamaki5602]

Holding the throttle wide open gives you a false Reading... So it only has 110...

[@codystelzer5700]

Thank you. I was going to say, that doesn't seem right. Never seen some one do a compression test at wide opened...

[@daroncraig8602]

You should do a 3 wheeler. Maybe a yamaha Tri-Z 250 or a tecate or a 250R.

[@gabe10222]

He has done both

[@BUFFALOBILLS1991]

I have a 400ex four wheeler and the best way to start a 99 or newer 400ex four wheeler is to pick it up and let some of the old fuel out not all of it just some, and then put amsoil in it and run none oxy fuel in it

[@camc7187]

You should look for a big red 250 or a 85,86 ATC 250r, also use that back brake as you’ll be able to wheelie down the road instead of just popping the front end up

[@gabe10222]

He has done that and a tri z

[@brandonmckenzie584]

I’d love to see you race your dirt bike vs the ex I’ve been creous to see if A 250 2 stroke is faster then the ex

[@brianj123458]

A 250 2 stroke dirt bike is faster forsure

[@zackcalfee4844]

That cr250 or 125 would burn up a 400 ex with ease bud

[@zackcalfee4844]

Even that kdx 200 would burn it up leave it in the dust, it's power to weight ratio a bike is only powering 1 back wheel vs 2, not to mention the cr is a race bike and the ex is a like a trail sport utility quad

[@zackcalfee4844]

But I'm wondering why the handle bars look like their having a seizure while on smooth hard top roads

[@cadenwest1542]

Zack Calfee the 400ex is not a sport utility by any means 😂 the thing is purely made to compete on dirt tracks

[@BUFFALOBILLS1991]

Every few rides your suppose to change the oil drain some of the old gas out, change spark plugs and Bearings, Starter, Put good oil in it, Transmission fluid, new Oil filter new air filter, check the clutch make sure clutch and Shifter works and brakes, check the chain, put good gas in it not the cheap gas use 91 octane gas for any dirtbike or atv it'll run better and use amsoil oil and if you don't clean the carb it'll start bringing metal flakes into the motor and ruining the motor period

[@allanmorton9478]

I would get that thumb throttle off and fit a twist throttle I feel a whole lot more comfortable with twist throttle

[@xRamRacing]

The reason atvs don't have them is because when you're cornering hard you're almost completely hanging off the side of the bike so keeping your wrist twisted is harder. It's also because atvs front ends are way heavier so when you hit a big bump you absorb most of it through the handle bar

[@SomeonewithaCar]

I have a 400ex and it looks almost the same I love it

[@rodneymoreland7950]

Shaking the thing wont make it run.

[@muntecummings7650]

u blew her up my boi😂

[@GoodlookinMug]

Excess oil is being burned in the cylinder bc of worn rings(oil & or compression). A cylinder caked with oil could make more compression than normal btw...

[@Eugenia_Farms]

i like that it wobbles really bad on the road riding, ill take it.

that thing is about to fuckin blow that thing smokin like a 2 stroke

[@rudyross5394]

I believe it’s the rings

[@connerjones7902]

If it was the rings it would probably have low compression though

[@jacknothnagel5011]

You can have a bad oil ring and still have good compression it’s not a two stroke it has multiple rings if the oil ring is bad but the others are not it will smoke like crazy but still have good compression, fix it don’t just sell it broke like everything else you buy

Also teach him to not keep riding a 4 stroke when it's smoking like a 2 stroke.

[@Builditathome-Restoration]

Joe do a electric bike build that would be awesome!

[@uslocks7186]

My 400ex is absolutely quick and loud

[@williamr8516]

Could still be rings, if oil is leaking past the oil rings it can seem like it has good power and compression, if your gonna open the engine up might as well get a fresh top end they are decently cheap

[@Hanky_Bannist8r]

If it was the valve seals it would allow oil to drip on the piston while sitting and once started it would burn off and go away. It could be a stuck ring or just blow by. Honda's will smoke forever before they need a rebuild.
