400ex vs raptor

[slamdak8782]

lol question iknow im going to get yelled at for this one anybody ever build 400ex to beat 686 raptor with porting and e series full exhaust. no turbo400exs either:rolleyes:

[EPDP99]

i raced a 686 on nitrous and beat it. but i know his bike wasnt running right. motor might have been fine but his nitrous setup was way wrong. i was maybe a bike length or more ahead of him and then he hit nitrous and a big white cloud came out of his exhaust and would make a pop and slow down.

[slamdak8782]

thats good stuff im working on my 400 right now and my buddys building 686raptor. If my 440 doesnt do the trick my gusseted 250r frame with extras will after the cr500 breathes in it

[tater_kamik]

tom, i am going to whoop that a** get a real quad!

[tater_kamik]

if i remember right, my warrior whooped your 400 tom...

[slamdak8782]

your high compression 350 with who knows what wlse kept up and my top end would have got you and my axle was bent you never beat me :mad:

[tater_kamik]

well, we always were even, but if you lost a few lbs you might actually beat me you fat a**:blah:

[tater_kamik]

I FOUND THIS PIC OF TOM RIDING A QUAD!!! ENJOY!!!

[400exredrider]

correctly built 416exs beat up raptors 426s built right and so do some 440s that are built right,,, this is going to take a high comp piston, cam, carb, pipe, filter

[tater_kamik]

here is what he is comparing his 440 to: 686 with 12:1 compression, fully ported with valve job, stage two hot cam, hinson clutch basket, gytr clutches. works shocks all around, +2 swingarm, larger oil cooler, pwr radiator. no matter if he beats me or not (i dont think he will) i could care less other than it is fun to talk sh** because we are going to have a great time riding. how do you think the 440 will do against it?

[400exredrider]

doubt his 440 would take that,,, it would take a 465 or 505 to do that

[tater_kamik]

how about toms 440 against an stock, or piped and jetted yfz?

[400exredrider]

nah
yfzs are fast

[DaleJrFan]

yall load up your quads and bring them to little sahara and run them straight up and we will see what can win. i enjoy sitting at the drag strip and watching some good racing.

[tater_kamik]

i dont know... i have watched quite a few raptor vs yfz and they are always close to even. yfz has a strong second gear though. i havent finished my raptor yet. its a work in progress! im always down for some riding though, just find a spot!

[DEAL]

I have a stock carbed 416 and can beat raptors off the line pretty badly but most of them will catch up on top end.

[slamdak8782]

I definetly want to try the desert thing. Me and Tatertot ride a lot and i think we are definetly going to try and hit up little sahara sometime this summer I gaurantee well have a blast riding there no matter who wins. I would be stoked just to keep up with a 686raptor but who knows. One of us misses shift that could be the race or if the carb isnt set up right. Its going to be alot of fun. Im going to start a post on the build up after the 440 gets done. :cool:

think maybe the rider had alittle do to do with that bro. my friend has a 04' 400ex piped, jetted, and k&n filter and the 400 doesnt' have the power to beat me or his bro's pred. on the line or top end. Raptor's have a lot of torque.

[400exredrider]

if a 440 is built up correctly it should do good,,, but for that id run a 12:1 or 13:1 on alky have a Sparks x6 full on it, FCR 39 or 40mm Hotcam stage 2, full port and polish, full valve and valve spring setup, ect ect. 400exs really get doggy in the dunes no matter what,,, they are air cooled

[tater_kamik]

tom is right, we are definately going to have a blast! i wouldnt do alky just because when you run out, you have to find a place that has it. how much would that suck being in a place you dont know without fuel while everyone else is riding? the rider has a lot to do with it definately. cant wait though :D it would be awesome if i could drop some weight of that fat quad, maybe i will just remove the radiator:eek:

[400exdave]

I raced a raptor today, actually my friend, at our mx track in town. He's got a jet kit/gyt-r full pipe system and i raced him with my 400ex (mods in sig). Well, Lets just say that It was a very good race..... for me. I took him in almost every spot on the track really. He will probably read this, which ill get a reaction outa him when I see him next, but it was fun beatin' up on that raptor! :devil:

[akraptor]

ok i'm the friend with the raptor. i stalled at the line. and he had me on the rhythm woops, one right hand turn that i almost overshot and one big table top. the rest was even or me gaining on him. and to my defence, he has riddin his quad alot more than i have mine. i've been out from riding hard for about month and a half because of shattered left clavical and surgery trying to clear the rhythm woops. He did beat me i'm not denying but it wasn't as bad as he is implying. lol. oh and i went over the handle bars again on some stupid little 2 foot woops the stupid track people put in at the end of a straight stretch. was kinda funny my head was stuck under my A-arms for 30secs before i could lift it off lol. but now my ankle is swollen and my left shoulder is pretty swore right now. So looks like i'll be doing 4x4 for this week. oh and he has the better suspension. look at his mods.

[slamdak8782]

see how it is when we beat them. proof that having less displacement and winning is a lot more fun:D

[400exdave]

haha, exactly. him stalling at the line is all part of racing. but yeah. 398cc vs 660cc.:D

[akraptor]

had nothing to do with displacement. straight out drag is all about torque. on a track is alot to do with the riders experience. and dave has alot more experience on that track than i do. but he didnt' beat me as bad as he first said.

[tater_kamik]

track riding definately has to do with skill. gotta love talking some s**t though! where do you guys go riding at?

[dunes_rider]

Can i beat YFZ ??

[tater_kamik]

what do you have? a lot of it depends on your riding. for example: drag racing, though it requires skill, will unltimately require a faster bike, but motocross will demand a good rider with good timing, etc. a lot of it has nothing to do with the bike!!! be a good rider on a crappy bike, then be a great rider on a good bike!!

we ride at a mx track in anchorage, alaska. more set up for bikes. narrow and not much places to pass. if not at the track, there are sand flats 30miles out of town. but that can be more fun with a 4x4 than a sport quad.

[tater_kamik]

i have always enjoyes a sport more than an utility, though you cannot beat an 4x4 in the mud for sure. the track i go to here is probably very similar, it is very small and definately made for bikes and not quads. though it does give you good practice

[prepracing]

426ex or 440ex with a rev box will beat a YFZ anytime, as for the raptor it would depend on what distance you race him

[akraptor]

yeah i noticed with my raptor it tops out real fast. raced my friends 04' pred and beat him by about half a quad length at about 1/4 mile. but he was catching up with me in 5th gear.

[dunes_rider]

prepracing: 426ex or 440ex with a rev box will beat a YFZ anytime


YFZ STOCK?

YFZ soo fast!!! How i can beat it??

and i have 400ex stock, after 1 month i will buy curtispark and AIR filter.:ermm:

[tater_kamik]

yfz's are fast, how do you beat them? high comp piston and oversized sleeve. not very expensive and very easy to do actually. just a little bit of work and you CAN beat a yfz straight line

[dunes_rider]

Thnx man , now i cant put any things on my EX , cuz i have exams now:( ,after the exams i will start ;) .

[prepracing]

the 426 I just bought has a white bros. rev box, stage 1 hotcam, hmf full system, K&N, aluminum air box, ported&polished head and a 168 main. I have raced both hon. & yam. 450's that are piped, jetted with K&N's. I beat both of them by about 3 bike lengths. One YFZ had a pipe, cam, high comp. piston and he had that deporting headwork ( where you make the ports smaller ) and I beat him by about 6 bike lenghts. I'm not to sure on that deport stuff yet, its not shown me anything.

[tater_kamik]

not understanding how a fully built velocity ported yfz would get whipped by an lower displacement quad that weighs more... you can build anything to beat a yfz, but it will be hard to beat one that is similarly built. after exams, hook it up (get with tom, he did all of the work including cutting the valve guides, porting, etc himself and knows a lot about that quad)

[prepracing]

I agree, or could have just been the rider. But that was just straight up drag racing so the gearing probably had alot to do with it.

[tater_kamik]

i suppose, im thinking something may have been wrong with his bike. i like to think anyone with that much work would atleast be able todo a straight line drag. or maybe the guy was a new rider and bought it as it was??

[MR.BIG]

A 426 will not beat yfz or a 450r. I can beat 440ex with my 450r and they have a lot more power than a 426!

actually most of the 416 426s that i ahve seen are faster than 440s. 440s dont revv as quick, but they do have gobs of torque

[tater_kamik]

i would like to see an dyno on all of the different levels of 400's tuned: 416, 426, 400, etc.

[MR.BIG]

That is true that they rev quicker but they don't have as much torque. I don't know all I can tell you is that I went riding today and the 450r is a rocket it's amazing the amount of power the thing puts out. If it was stock I think a 426 or whatever displacement you have might be able to beat it. Put a pipe and the hrc kit on the 450r and it ain't gonna happen unless maybe its a pure race bike and that's all it's good for. Honda rules no matter what!

[dunes_rider]

OK MR.BIG


i know 450r is more power than 426


Can u try with a YFZ ??;)

[tater_kamik]

i cant help but think more displacement means more power... but there are a lot of factors out there. i feel that no matter how much power it may make, it still depends on the rider. that is just me though

[khen]

My buddies got a YFZ with the ESR intake kit, full NMotion exhaust, Dyna CDI and the cam mod. He's a light weight at 140lbs and I've only seen him get beat by one other YFZ drag racing and one 450R and both of them had engine work. Anyway, we were at some sand drags a couple of months back and there was a 426EX that was giving him fits. I'm sure he lost to this 426 more than he won. I don't know what other mods he had on his 426, but my buddy asked if he was running NOS or alcohol and the kid said no, he was running the stock carb. :eek2:

My buddy is very practiced at drag racing, but so was this kid. On the same 500' drag strip I lose to my buddy by about 3-4 quad lengths on my 416EX. I also weigh about 60lbs more than him so that's part of it. He gains about 1.5-2 lengths on me through the gears and the rest on top end. I recently went back up from a 14t front sprocket to a 15t to see if that would get me closer, but I haven't had the chance to drag race him again.

[blue416ex]

threads like this make me appreciate my ex and show me that the ex still has enough nutz to hold its own against these 450's:macho :devil:

[dunes_rider]

ok guys now as u know my 400ex is stock but do u meant if i had a pipe, high compression piston and an oversized sleeze will it do the work in kickin a stock yfz ?

and if yes then would there be any problems ? i mean when im riding i dont usually race my quad i just ride for about 3 or 4 hours a day in the summer and sometimes the temp in UAE gets 36 or 39 so will there be any hard effect
on the motor after the mods ?
