400ex vs. other bikes

[trailbossman08]

Can anyone tell me the advantages of getting a 400ex over a different bike?

Like is it easy to get parts for?
Easy to work on?

The 400ex is a quad, not a bike:p

Parts for the 400ex are very easy to find...

[TYayo420]

i call it a bike too alot of ppl do around here, either way get a 400ex, im not going to sit and debate and compare them over any other bike, its a plain all around, good, fast, powerful, fun, reliable, awesome machine. I always wanted a 400ex month or 2 ago i got one finally. awesome machine get one and stop questioning it when you could be out on one

[exridr400]

i agree. I have one. it is fast powerful awsome at wheeles, and riliable. I never had a problem with it. I no a couple of people with them and they have beat on them pretty good and they still run good.

I love mine to death, i rode a Suzuki 400 and 450R (both cost more) and I like the feel of mine the best. :D

[Kaleigh]

easy to ride..
very forgiving if you dont take care of it..
lots and lots of mods for great prices..
really easy to work on.. the 400ex is my very first quad and I have never ever brought it to a shop.. not even for the first 20 hour tune up.. oh yea.. and you dont have a big mess of a rad..

I was riding in the sand one day.. didnt notice while I was riding that my airfilter(open air) can undone and was dangling there.. rode about 2 hours straight before i noticed it.. the piston looked kinda crappy but the bike still ran with no problems what so ever..

the 400ex is like the tank of all quads.. beat the crap out of it and it still wants more..

[cc_z400]

look you got your ford guys you got your dodge guys what ever it may be z ex kfx all are a blast just get one of them and your not going to be unhappy

of course.. but one thing you have to understand..
one is gona be a little easier to work on..
one will have more mods of a better price..
there are advantages to anything you buy..


but the best thing i would have to say about the 400ex.. there are so many of them that you can pick a used one up for real cheap..

:macho

[miller821]

Depends what your gonna do... Racing = 450. Normal riding = 400. Though the 400 can be a race quad I would go with a 450.

[TYayo420]

if your going to go with a used kfx 400 or a z400, go with a z cuz suzuki made the kfx too, why buy a suzuki quad with a kawi name on it when you can just buy the suzuki one itself which looks better anyways? id still say 400ex tho

[Ruby Soho]

400ex is a fun quad. and the #1 thing about it is its reliability. its bulletproof.

[Flyin400]

Ya i would say so!

[hondaracer_34]

i agree...ive had mine for 3 years, bought it brand new, and the only thing gone wrong with it is the bearing carrier which went out last weekend..i love my 400ex

[XXXRACER165]

Ya they are really a good quad to start on, and you can keep adding-on to them as well. My dad bought a '06 450R w/ a HRC kit installed, he likes it but prefers the handling of the EX. Of coarse mine is far from stock:D

[trx400EXtreme]

like others are saying, VERY easy to mod because its been around so long. reliable. mines an 02 and its never broken down. fast, its a honda:D :blah: ..... tons of other reasons.

[gncc025]

GREAT quad period. i have put mine through everything possible in stock form and it has held up great. although i have gotten a complete frame replacement. but that was due to big air with stock suspension multiple times lol:o

[Batavia's450r]

ive owned several ex's from stock trail riders to built to the tilt race bikes... still own one and its alright i dont think i could pick up any more aftermarkets for it!! but when it comes down to winning races i saddle up My 450r and ripp but its not for the faint of heart if you want to put gas in it and ride go with the ex if you want to win championships go with the R youl regret it when you come to the track with the under powered ex... its amazing on trails just doesnt cut it on the track and the R is all around amazing to me ive owned mine for a while and even for the first few weeks of it being stock i loved it!!!!

as for the suzuki and the kawi they deff have nice features the ex lacks for the trail rider.. reverse, LIQUID COOLED... etc.. and id go green cause i like the color haha

RIDE RED THOU you usually dont regret it

[j450rking]

when you ask in a honda section people are going to say honda when you are in a Suzuki section people are going to say Suzuki.

but when you do some searching you will find that there has been more problums with the z kfx and dvx (all the same quad) then there has been with the ex so there you go

[450rJam]

great handleing
good power
great aftermarket
great dependability
easy to ride
good e starter

easier to tell you the bad points
air cooled

haha i did fine against a couple of yfz450's and a z400, with my stock but pipe ex my first race, alot is rider, but a ex is a great machine, obviously if you want speed get the r

Not down here, they almost want7K for a 400Z, when i paid 5400 for my 400ex

[Anvil]

Howdy people I'm new to the forum.

I really like my 400ex, had a good ride on a 400z and it was felt more refined and had more go, but has way more mechanicals to bust up. I like the fact that the ex is uncomplicated with well established mechanicals, but each to his or her own.

[JimmyHoffa]

Ex's are much cheaper than z400's on the used market for sure. I wanted either one, but went with the 400ex partly because ltz400's were hecka expensive. New, the 400ex is 100 bucks more. (assuming the best deal.) This is just FYI, depending if you are thinking about buying new or used.

lol, i am sure you did fine against the Z, but the yfz...lol ok :o it takes more than a pipe to run against a 450 of any make. or the guy on the 450 completely sucked and was an inexperienced rider.

This is totally possible with a experienced rider. I think TYayo420 is a good rider so it's deff possible.

so the yfz finished behind you TYayo420?

XXX have you seen him ride or you just online "friends" with him?

if you will notice in my post i said that the person on the yfz could be beat with an inexperienced rider on it.

but anyway what are you running?

No I've never met him but I can usually tell if there is a fast rider or not, and I'm running this

LOL you can tell by their posts if they are fast or not? LMAO!!!!!!!!!1 :devil:


and i meant, what kind of races are you running. looks like XC

[TYayo420]

you wanna hear some funny ****? the first week of the summer series, a guy on a polaris scrambler 500, won in his class against 2 raptor 660's and a 400 ex, anythings possible man i figured the polaris woulda got smoked.

idk why you think i didnt beat a yfz or anyone cant on a 400ex its alot more rider skill then speed man, think about it, who can handle their quad better into and out of a turn has more speed=going faster, better lap times then a guy on a yfz who cant go through a turn on a fast quad then someone else

people with yfz's are under the understanding that there quad makes them better than 400s automatically. its still 90 %rider 10% machine. sorry you spent so much money.

[IRONMIKE113]

i go with that my just got at thunder on sands in jersey he was in first on his R then got hawked down by a 400ex

i think that a 400ex can beat a yfz, but NOT with equal riders. like i said before he might have been unexperienced. i dunno, i wasnt there.

i HAD a 2001 400ex. it had a thing or two done to it. the 450 is better for me, i am glad you think your 400ex is fast, thats great.

but anyway didnt spend that much money, by the time i parted my 416 out, i figured it up and would have had more money getting more power out of the 400 to get it to the performance level of any 450. it is just a better platform to get power out of compared to a 400. and i spent 4-5 years on my 400 bud. after a couple seasons of racing small stuff was starting to break. just normal. it was a good quad, so far i have gotten good service out of the 450 and it hasnt left me stranded.

yes it is 90 rider 10 machine, but if we are equal riders, and one machine is faster than the other, who will win? :confused:

i think the faster machine will? maybe im wrong though. maybe you can fill me in on that?

he must have sucked, i have not came close to loosing to a 400 of anykind. a 460 stroker ran with me. that is about it though. and my motor internals are stock beside advancing the timing.

I can eat a YFZ450 with advanced timing

at a drag race, or what?

[XXXRACER165]

yes at a drag race and it also had a Ron Woods intake with a
Dr. Dubach full exhaust.

[Dill]

I'd like to see that sometime, and I live nearby too. I know the YFZ and 400ex engine real well and find it hard to believe a good running YFZ would have any trouble with a 440ex.

[oldskoolex400]

oh yea, and XXXracer nice 400 man, any chance you have a mods list on it. looks like a pretty clean quad.

thank you very much, yes I do infact lol go to the pro armor quad of the month and look for my name on the forum.

ok, i dont care. mine is full pipe and pro flow intake w/ adv timing. i havent lost to a 440 426 416 yet, the 460 stroker was pretty fast, we were side by side til he topped.
i havent seen a yfz locally that is running correctly that lost to one, but if it has been ragged on i can see it happening, esp if the rider was inexperienced.

you're much more politically correct than me. I agree with you! :D

[XXXRACER165]

Dill Check your PM

[oldskoolex400]

here is an older pic of my 400, bout 6 months before it was parted, had a few things that still werent on it, got new nerfs, bars, houser steering stem, i cant remember if the LSR axle was on there or not, looks like it was idk.

[oldskoolex400]

1 more, got the old works on it then, and no beadlocks.

[Got Boost]

42 hp who did your porting? and you must have a well built motor, and a stroker motor at that, KBR built one that had the biggest stroker,cam,port, best of everything and hit 40 hp, there is no way a 400 or ex can stomp on a yfz, when you pipe a yfz you are @ roughly 40 hp, that is with a decent pipe, and an intake adds a little, but cmon, that bike must not be running a full potential, the two have totally different torque and power curves

[sdbrown12388]

i have both a 400ex and a yfz and my 400ex has only a slip on but even with a whole lot of mods i dont believe it will ever come close to my yfz

[XXXRACER165]

Well, if you know NHRA pro-stock bike tuner Rick Ward he is the one who did the port work for my machine. He has won multiple championships with the porting that comes from his shop & only builds maximum performance engines. It was a special favor my dad did for him, so in return he ported the head for me. So I don't think he would do it again. But anyways, I was at the Little Sahara dunes in Oklahoma and was with a friend that had his YFZ450 there. He did the timing advance, a Ron Woods intake system and a Dr. Dubach Step full exhaust. He also had paddles on, I had Holeshots on. When we raced in a straight line he couldn't pull away from me, his machine is jetted perfect. I really wish I had a pic of that to show you guys his face when I stuck like glue right to the side of his machine.

that was one yfz, who cares? you havent raced anymore man lol, my 416 ran against 4 stock 04 05 450rs, but u i ran a piped one before i got rid of it and it killed me man. right before it was taken apart i took my yfz out and a friend took the 400 out, he was about 60 lbs lighter than me, and the whole time down the road i had to slow down, we stopped a few times and still the same outcome, i could have easily passed my 400. i just dont know about that 42hp, did u ever get your dyno sheets to prove it?


here is a stock yfz450 gt thunder dyno

[oldskoolex400]

heres your slip on cam mod lid removed and jetted

[oldskoolex400]

In this graph I have the cam mod done as well as no airbox lid, 170 main jet, #5 clip position on the needle and the stock pilot jet. The one run is with the stock silencer and the other run is with the new HMF full system exhaust. Yes I had to beg and many other things to get to test this and no I did not get to keep it but it sure looks good to me.--gt thunder

[oldskoolex400]

here is one more with the spark arrestor simply removed. no carb changes or anything.

[oldskoolex400]

that is all, i could ramble on about stuff, the numbers are on the table for all to see, there is no arguing now, a 450 with anything done is putting more power down.

[XXXRACER165]

Rick said with all the mods done to my stock 27hp motor it would gain a MINIMUM of 56% more power. He has been building motors for years. That % wouldn't come out of thin air or be made up, I can't (well now I can) believe you need a friggin' dyno chart to believe that.

lol lmao, well when i put the green powerband with my other mods in my stock 40hp motor it has a MINIMUM of 76% increase.

i can throw numbers around just as easily as anyone else. that is why we need a dyno chart to believe you. and since you cannot provide one your horsepower is unaccurate. so in that case we, i think i can speak for most of the members of this site dont believe power output until we see a dyno chart.

also you said you dont think he would do it again, so it sounds like this is the first 400ex motor he has built, so how can he know what kind of power increase it will have?



:confused:

[XXXRACER165]

It was in my fire case, so here you go.........................dyno's don't lie!

[oldskoolex400]

ok, i believe you about the 42 horsepower, thats about it though.....

did you dyno that in MN?

where is this place? I wouldn't mind dynoing my YFZ. Is it a dynojet or superflo dyno?

Dynojet and I'll have to get back to you for more info, to much chit going on at home pops is building a new garage! later!
