I had a "YFZ450 running Odd" video on my Youtube page for the longest time.. -What it was, I re installed the AB lid and it ran like CRAP!!! After some diag and asking around here it turned out to be that my quad wasn't jetted to run w/ the restrictive AB lid ON... (back in July last year or something)


Anyway... I got a comment on the vid:

"Junk that POS! You keep trying to jet that WooTin thing, or go EFI! I'll see you on the trails... Raptor 700 All the way!"

It was quite a bit more 'colorful' than that, that's all I could remember.. . I ended up deleting the vid because of people chiming in to tell me my stator went bad or some crap... I kept mentioning that the vid was VERY old and it was the AB lid...

Anyway.... I know some people can be very biased about their rides, but to post a comment like that on someone's page..... Wow... You're a big man, flaming someone on the internet... I don't even waste my time arguing...


Sorry.. that kind of ticked me off...

Carry on..

Ya, some people can be real wooters sometimes. They dont realize that quads are made for a specific public. I'm not an EFI fan just because its one more thing to fry when I wash it. Its amazing at how many people will post on something they do not even read even if it has already been fixed. There was a thread on here about a guys swingarm and he had already found the issue and some ppl kept posting it was his subframe, funny stuff.

some ppl are just like that. I love my EFI and wouldnt have it any other way. Its not gonna fry when washing though. Ive had too many wash jobs since it was new in 06. Diff strokes for different folks. Just ride safe and have fun.

next time give them a place a time and all that to race ....theyll all punk out internet tough guys....we all have are moments tho

I only own on EFI machine but i love it. Its a zr 600 and it doesnt matter if its 40 degrees or -40 it runs great and starts in three pulls (not even joking)

Personally I wish the YFZ450's were EFI ... I don't see where it's a bad thing at all anymore. I mean seriously, what's easier? Programming something with your computer or messing with a carb? I'll take the computer any day :)

^ yeas and no... I think the programing will be a little more expensive... Or when it comes to upgrading fuel injectors, MAP sensors (Or whatever they use), or O2 sensor replacements...

Jets are what, $20??? Cheap and easy first... easy to replace.. I'm haveing a REALLY hard time learning this tuning thing for my car, I wouldn't want to mess with the quad... Spark tables, injector flow rates, MAF/MAP settings, WB O2 sensors are like $430, tuning software is like $400+..... etc etc... That's just the basics... In order to get your spark tables EXACTLY right, you'd need a dyno, add * of timing untill you no longer make power and then back it off 2*.. THis is going to take a lot of reading to get to know..

Where do you get your jets?! Mains 3 bucks pilots 5!

My zr 600 carb starts on the first or 2nd pull. The way I was told by the dealer EFI should always start on the first pull. Even my race sled starts on 2nd pull.

don't you have a camaro?you tuning yourself?I am about to get efi live

^ LOL... I got my last GYTR kit thru Ebay for like $12 I think.... I just meant that they arer cheaper than a fuel injector..

i have the PCIII from dynojet and i can tune mine to the "T" to get maximum performance.. not just getting close.
I think the guys that have went with 797,804, 869 builds and such like getting a bigger injector but as far as i know anything less is fine without it. No O2 sensors on our unless you get that wideband kit. I think my buddy bought one for 230ish.
The pcIII is 256 shipped to the door from www.fuelmotousa.com
I guess the big advantage with efi and the programmable computer is that for every mod that i do i can tweak it to get max HP for that specific mod. You dont have to keep the same jet in and say "well it isnt gonna make that much of a difference... its alright".
I wouldnt mind having a YFZ to build and play around with.. but for the money i could get a kenz or rocket factory build on mine and have to pick on 30k dollar banshees or streetbikes.

Technically you wont get maximum performance with EFI. A properly tuned and jetted identical quad will out perform any EFI setup. The key is finding that golden setup (That is where EFI shines over carburation because its easier and faster to get closer to that magical setup).

I must say, the YFZ450 is by far one of the best sport quads out there and between the raptor 700r and the yfz450, I'd take the YFZ450 over a raptor 700 anyday just because for one, a yfz450 is wider and it handles better on on the track. and plus a yfz450 has good performance and also can have more power added and the yfz450 can be tuned for better handling to go with the power gain.

The raptor was actually rated higher for new riders due to the gearing (riders could navigate a track with less gear shifts than on a yfz). The YFZ was said to be more for a seasoned rider that knew more about the track and clutchwork. This analization was made in QUAD Magazine.

yea, but you can't believe what they say in those magazines. sometimes they don't tell the whole storey behind all of it. actually they don't tell the whole storey behind it all. But I wouldn't know about the raptor 700 cause i never rode one, alls i know is i like the 450's and nothing else, well besides the yamaha banshee, cause that's a legendary 2 stroke and wild machine, but other quads, i wouldn't want to even bother with cause to me, nothing else is better on a track than a 450 sport quad.

yfz is definatly better on the Mx track

A 700 does have taller gears and requires alot less shifting on more technical tracks. I'm not saying the yfz isnt a better race quad. You wont see a begining rider out on a mx track very often.

i agree with you for the most part.. but you contradict yourself because you say you have never ridden on a 700 and know nothing about it but then you say you like the 450 and nothing else.
And the yamaha banshee.. ur kidding right. id rather have my 700 with some mods.. lol. My dream would be to live somewhere with some dunes and have a 907 raptor. No banshee is gonna touch that. The raptor has been king of the hill out west for a little while now. Lots of them guys from www.kenzcycletech.com and www.teamrocketfactory.com have been busting ppls heads out there. Im a drag guy so i dont know alot about mxing other than the 450s are better on the Mx track. No way id take anything else over my raptor for what kind of riding i do and i have ridden the majority of the quads out there.

Yeah.. I've got a 2000 Z28... I WANT to learn to tune, but it's VERY overwhelming and I'm TERRIBLE with numbers!!! I figure I could save a lot of money doing it myself, not having to wait and/or drive 100+ miles to get it done..

I'd also like to add that the 450 is balanced better... It wheelies on command, but stays planted when you want it to.. The way I see it with the 700; if you lean forward to keep the FT end on the ground you'll loose traction, but if you lean back to get traction, the FT end will come up.. Too much power, IMO, for an MX track..

I MX occasionally, but mostly I'm a do0ner..

Well yea, I did contradict myself, but hey, everyone has their own taste for the type of quad they'd ride. I mean I'm a mx and sx type rider, so I like the 450 because it's best for the tracks, quick, fast, light weight, and i also like the looks. A raptor 700 I'd use for trail riding if i had to choose a quad for trails, but since i like the 450's so much i'm going to ride 450's on the track and on trails, and maybe when i get a banshee someday, i'll probably try racing that sometimes in a mx race and mostly i'll ride it on trails. but someday I plan to have 2 450's, one for mx and one for sx and the banshee will be for trails.

If you want to Mx race, the 450 is without a doubt a better machine

If you want to trail ride or dune, the 70 is an awesome machine as well.

For less money a 700 will go faster in a straight line than a 450, and theres lots more potential for the 700 to make some serious horsepower.

But for the money, a 450 is much better for track built purposes. They are the same width, but the yfz is lower and lighter, much easier to toss around.

The 700 is actually very controllable compared to a Yfz, the yfz has a hard hitting top end that totally kicks ass, but the 700 is very docile and very easy to control. On the 660 Craptors they would come up on you, but it's not like that with the 700, very easy to control due to the head redesign and Efi set up.

I've built many more 450's than Raptors that's for sure. But the only reason I went with a 700 as my next quad, was because of the seating arrangement. The handle bars, to pegs just feel better to me at my height than the 450 does. I'm sure if I was shorter I would have gotten the 450, because they perform excellent.

I'm pretty tired of these kind of threads honestly, people need to have an open mine. There's a reason why the Yfz and Raptor are holding the top 2 spots in overall marketing sales, it's because they both kick ass.

^ I didn't mean for this to come off as Rappy bashing.... It was just that close minded comment left on my video that got to me..

I'll try my buddy's 700 one of these days.. Sure it's not like the 660..

Sorry, didn't mean to come across as a dick. I know you didn't start this thread for comparison, you tube is nothing but bashing, that's why if I do post a video I disable the comments. It actually seems like quad videos are the worse, it's always "Your w00ter sucks dick, you should get one of these cause I have one" and no one can appreciate other peoples tase.

I have a Raptor 700 and love the 450.

I wish I could have both :(

yea, and I'm not bashing on the raptor 700, sorry if I came accross it that way to any of you, but I'm not. Like we all would say, everyone has their own taste for the type of quad they would ride. Some preffer Mx/SX, and others preffer trails, some preffer cross country, and some preffer Flat Track, and other like freestyle. But no matter what quad you choose, it's not going to make you a better person than everyone else, just because you have a fast quad, doesn't mean you can ride it.

Sorry but I totally agree, I just laugh my ass off when people start to try to show how "intelligent" they are on the net. Especially on this site. OMG like a lot of people just got in a huge wOOting argument over that depression topic. All i got say is find somethin better to do than argue with people and bash them over the net. sorry thats my 2.

And to add to the 450/Rappy thing. . . I have the 450, I dont have the intention to race my quad. . due to the fact when i feel like getting my ass kicked, ill head over to the track on my bike lol. . . I love my quad, dont get me wrong. However, I rode a 700 last time i went to the dunes and i gotta say . . WOW! it was nice, I think you cant go wrong with either for duning, but for the simple fact of $ vs. $ and mod for mod. The Rappy kicks. but still thats a stock 250 cc head start outta the gate. . the real competition is getting your 450 to beat a 700 in straight line up a hill. Thats the true underdog story. . . and the only reason i say this is because my buddy has 700 with PWC, Dynatek CDI, Intake, Exhaust, and Cams. . and the only 450 Quad that came close was a big bore stroker, but it all depends on the rider and your holeshot and gearing and jetting and. . and . . . bottom line is my buddies 700 is FAAAST . .(in a straight line) lol. I can still jump higher than him though
