hybrid 426 vs. YFZ

[Ryan8R]

I know a guy that has Dunks old 426 motor in a four wheeler...Its stroked to a 440 has 13:1 compression lightened flywheel and some other things. I rode it and its bad ***. Some people tell me that a YFZ, which i have never ridden one, will outrun that 426. I say thats a bunch of bull. How in the world is a modded 426 motor gonna loose to a YFZ stock. THe only reason im saying anything about this is because some people i was asking told me that it would and some people that i didnt ask told me that it would. So what do you guys think about that??

peopel think those 450's are the fasting things ever made... they are fast... but they dont "smoke" any otehr high performance quad by much.. .. line em up and tells us what happens.

[shamisc]

I raced 2 new YFZ's yesterday that were stock, and NO, they were not faster than mine or my buddy's 11:1 416 !! They were fast to be stock in my opinion! They did outrun piped Raptors in the 1/8 and the 1/4 ! 660 piped vs 450 (439) stock, and 660 loses? Go figure !:confused:

[BigAl]

I have both,a YFZ and a hybrid 426 that belongs to a buddy that we built.

In stock trim, after jetting and pipe , a YFZ will not outrun a stock 426 hybrid.

But a YFZ is MUCH easier to ride, and not much slower.

If you change the cam timing, and up the compression to the 13.?:1 that the hybrid runs, they would be about equal.

If you have not ridden a hybrid it is hard to describe how hard the power hit is. That is the main reason alot of riders went to the CRF motor over the YZ, because it has less power, and it is easier to control.

Now, before you kids get in an uproar because I dared to say the CRF has less power, I am talking about the BIKE motors of the last couple years.

Power isn't everything, unless your drag racing or internet bashing.

Well said!

Have you ever seen the videos on YFZCentral of a stock YFZ450 match racing against a 686 Raptor and the others against the 416EX, I have to admit the 416 put up a great battle but even with inproperly inflated rear tires and driving off the track the YFZ still motors by with ease.

I just like to see proof in all these forum struggles..... Videos people!!!

OK, i am getting tired of these ex guys saying "my 416 is faster than a YFZ" bring any ex out to Pismo that is running gas and is under 465cc and i will smoke it. Now i am not just talking out my *** either. i just have basic mods. I can beat a 440 with EVERYTHING on it by about 3-4 bikes. I am also right there with 465's. so if you are going to bash my post and think i am just talking, bring your bikes to Pismo, hell i'll give you my cell # if you want thats how bad i want to smoke some of you.:grr:

[KrazyKid300ex]

i think the hybrid would take it over top end but maybe a yfz in the beginning becasue the yzf motor has 4 gears right? wouldn't it be alittle sluggish vs. the 4 speed beefed up tranny for a quad yfz motor?

[BigAl]

no, there is nothing sluggish about a YZ, anywhere in the powerband.

but you are right about the 4 speed.

[RiPPiNiTuP7]

there is no way in hell a 416ex will beat any yfz unless one of the cams were removed or something, lmao.

[AlaskaSpeed]

It's fools like these that were singing the same song about Cannondales too. All hail the all powerful 416EX...LMFAO........:rolleyes:

LMFAO Looks like i dont have any challengers. lol they talk the talk but dont walk the walk.

Come on.... You know that 80% of the members here dont even have thier drivers licences yet. Maybe you'll have some takers if you offer them a ride there :p
The other 20% know the facts.

[RED121572]

Are we all talking about out accelerating or top end. If top end is the issue, Ill get the largest c/s sprocket made, rev box and Ill challenge anything out there to a high speed run. :D ;)

How about 460? I've got a 425 that would take the deal too...but its not a 4 stroke.:blah:

Lol i know that a 420 cc 2 stroke is out of my league. is it a shee? also i will race your 460 but i know i will lose. I am going to be out there today. and all this week. i send you a pm

[Chef]

No the 425 is an R. I sent you a PM back, as well.

Some input from a YFZ and a 416EX owner.

At the Ironman GNCC this year I had the opportunity to hit a field section side by side with a stock YFZ and me on my 416. I was shocked to see that we stayed together through the whole field. I was expecting to get left behind after racing a piped yfz at an earlier race. I thought that it was just the rider. That is until after I ran my stock YFZ wide open. I must say that on top end it accelerates no faster than my 416. After riding it in the woods so much I expected to be faster in the open areas than it was, especially since it revs so fast. I'm not saying the engine is not all it's made out to be, but that it is too restricted to run like it should on top end.

the dyno for a piped yfz vs a piped yz...the yfz had more ponies,


who cares tho, the difference in a yz and yfz isnt going to matter the yfz is just as competitive and more durable for atv use

anyone would be happy with either

something is wrong with your yfzs if a 416 out accelerates it, we drag raced, my 416, my nephews duncan /je 416, and the yfz smoked both of us with a heavier rider, had the cam mod and pea shooter removed

I just got back from Pismo and i raced a 440 with cams, high comp piston port and polish ect and in about 150 yards i beat him by about 5 bikes. I also raced a 465 stroker on alky and he got me on the top end by about 1-2 bikes. But i was a very close race. Later

Seena 2 piped YFZ's get smoked by a ported 250R about 3 hours ago. These kids have no clue.

ROTGLMFGDAO!!!! you think just a ported 250 is going to beat a piped YFZ? lol Dude i keep up with built 350's built by ESR. And all i have is pipe, cam mod, intake, and jets. I will absoutly smoke a ported 250r. lol you have no clue:o Kids these days.:grr:

[C41Xracer]

my 265 eats piped YFZ all the time

[member]

who cares whos is faster?? i mean it's like some of you have a life long goal to prove you are better in one way or another then someone else is....:rolleyes:

Yeah, I think I'll ship my bike out there and get the old lady to book us some flights so I can out run your __________?:rolleyes: You never even stated what you ride! The post is about a hybrid 426 out running a YFZ and I was just saying that the YFZ can't outrun mine and I can't outrun a hybrid, so I think the hybrid would be faster! So...... isn't it past your bedtime teeny bopper? I think your mommy just called bedtime!:rolleyes: No internet after dinner!!:blah:

Every 416 is not the same ! Compression, portjob, head flow, etc, all play different roles on every individual bike! But, like I said, My buddy's 416 DID outrun a STOCK YFZ period.:macho

shamisc dont be a dick. I will beat any 416 you put infront of me. Oh btw i didnt ask for you to ship your quad down here i didnt even refer the statement to you. Oh i also ride a YFZ. So you can go to bed now you old fart.
:devil:

you guys are great, let me get some more popcorn, brb.

Dude, dont even talk anymore, you just said you keep up with 350rs built by ESR, thats bogus. A 350r would crush a piped 350 banshee, and a bet a piped banshee would beat your yfz. I would also like to see you "smoke" a ported 250r. Sorry for flamin but you talked alot of bs in this one. Whats funny is theres a girl whos dad bought her a yfz450 and it wouldnt come close to a piped banshee... hmm.. I guess that cam mod,intake, pipe, and jets must do miracles.:eek2:


Just to tell any yfz owners out there, not flaming them, i think they are awesome machines and would love to have one. No flames intended.

they do miracles for sure that pipe is very restrictive, thats not the first time i heard of a yfz beating or coming near to beating 310-350rs

I donno man. thats like saying a xr250 fourstroke is going to come close to my cr250 2 stroke.. I cant really say too much of the Rs becuz i have no experience with one..

Yo Mama thinks I do good for my old age!:rolleyes: Man, you're really dumber than I thought. Anyway, have a good one, learn a few things from the people on this site, or go to your Yamaha site! :macho I'm done here!

Dude thats not cool. my mom is well.....:( :( You shouldnt talk about other peoples home lives like that. Your ****ed up.

Here is a video of a YFZ beating I belive to be a 370r.
http://www.ljsoftware.com/Videos/yfz.wmv

You call that a race? The guy didnt even have the throttle open, in fact, it sounded like he was warmin it up and revvin it up. Turn the volume up once then you will see, if he was crackin on it, shlt would have hit the fan:devil: Throw me on a 370r, ill race you, you wont even come close:o

Well, a 370r is very fast and once i get some more mods done i think i will be able to take a 370. :macho

excuses excuses:o

[gibson400ex]

that might have been a 265r or a 310r maybe:rolleyes: but seriously do you really think a 370r with extensive and thousands of dollars into the motor alone could beat a pipe yfz wiht a cam mod and jetted and stuff........NO way it couldnt........so get over it

[gibson400ex]

Bobby88 is on the money it mgiht happen but to me i doubt but it couldn happen but a 370r could hit close to 80 with extensive motor work.....a piped yfz and jetted and a cam could hit maybe 54-58hp i dno

[gibson400ex]

and when i am in Va Beach for the Va extreme weekened for drag racing and mx racing i will see if a 250r will beat a piped yfz and stuff.......and i will let you guys know........even though the Va thign isnt for a couple of Months

[raptor_02]

lmao, i have read some really funny post on here. A 416ex beating a stock yfz, hahahahha. NO WAY that's going to happen. The only way a 416ex could beat a bone stock YFZ would be a 416 national kit that cost well over 2 grand. And I don't think any of the 416's mentioned has that kind of setup. But then all you would have to do is throw you a GYTR slip on, 172 main jet, and remove the airbox lid on the YFZ and you would take a 416 national ex by 5 bike lenghts or more. No EX is competitive with a YFZ. If they are, it's because you wasted several thousand dollars making it that way. Bottom line, a YFZ with just 500 bucks in power accesories is by far quicker than any atv out there. I'd put my YFZ up against anything that's 250 class legal in GNC rules and probaly win 9 times out of 10 in the power department. But for those of you who think a 416 will run with a YFZ, stop kidding yourself, THEY WON"T!!!!!!!

[member]

haha ill take on any stock yfz at the track with my 400ex:p

[raptor_02]

lol, just think if your smoking YFZ's at the track now on your 400ex, just think how bad you would smoke them if you were on a YFZ!!! or a 450R!!

[member]

yea but if i had a yfz id probably be fixin something on it, and the only reason its faster is cuz of them stupid stickers, take the stickers off and see who wins:o

[member]

o and i only got the 400ex as a starter bike anyways, ill do a few minor engine mods then after a year or so i will probably look for a 450r motor, and if it dont fit i will make it fit:)
