Hey guys i am trying to post my pics and it say that they are too large. How do i make then smaller??? I am not very good with this damn crap.

 

Ha ha, I was trying to figure out how to that the other day too....good luck!!

 

Install some photo shop software on your computer, then you can resize them.

 

I would like to share my experience with the 700r vs. yfz450 saga.
My friend and I both bought brand new Quads at the same time, My buddy bought a 05 YFZ 450 (he likes yellow) and I purchased a white 700 Raptor. Right off the bat, He installed a Athena 480 kit with a HMF pipe, Cam mod, and jet kit after 10min of run time. So I followed with a HMF full system, Powercommander 3usb, and a Trinity intake kit. We went to the Glamis dunes and gave them a run. Both our experince levels are comperable, He Rides dirt bikes (owns a KTM450) and I used to but it has been a while. Racing up Oldsmobile hill, it was a even exchange, whomever got through the whoops first usually won. If he beat me through the whoops, I could pull him ever so slightly but not enough to even make up a bike length. I was running Skat Trak haulers 20x10x10 9 paddle haulers and he was running ITP sand stars. When he tried a set of Haulers, he would pull away from me in third gear. Needless to say, he now runs Haulers and says the back end does not dance around anymore through the whoops. I tried shifting into 4th gear and the bike pulled it. I felt stupid never trying it before, it just did not sound like the engine would pull it, but it did. Now, even with the Skat Traks on the 450 I could still pull him sightly. Not enough to win if he beat me though the whoops though. I leave the line in third gear, go through the whoops and shift to 4th. Both of us are experienced tuners and both bikes are very close in tune. Glamis is a good test of a bikes suspension, and horsepower. 200 ft of whoops at 40mph followed by another couple hundred yards of uphill sand is a blast. Both bikes do 42 to 43mph up Oldsmobile hill using a garmin GPS track function. The 450 "IS" the bike to beat and the suspension is better on the 450. The Raptor 700 front Harly style junker shocks work better than they look. I think Yamaha is looking for a $7000 price point on their bikes and the money for the fuel injection had to come from somewhere.

This is where things get interesting, I purchased a set of ELKA front shocks dune edition (compression and rebound, dual rate) and this my friends is the best money you can spend. My buddy purchased a set too, he could not believe it, our third trip to the dunes was all smiles. cornering was the largest improvement, on both bikes, we just starting hitting stuff (angular) that would normally try to through you off the side on purpose now. I now have a rear shock on order because I could feel the rear end pack after about 4 whoops. the front is now better than the rear and the raptor rear shock is pretty good. Now I know why you never see anyone winning races using stock shocks. what a difference, why pay for a doubble adjustable shock if you are just going to take it off anyway right?

Now comes Trinity 734 kit with a ported head. No contest, hands down Raptor 734 wins. Piped, jetted, big bore, intake 450 to piped, jetted, big bore, intake, Raptor700 no contest. I went from 43MPH up Oldsmobile hill to 52mph AND THE BIKE IS STLL RICH. The clutch started slipping when I started pulling fuel out of the powercommander after a few plug runs. Remember, the raptor and the YFZ 450 use the same clutch, how many 450's do you hear of the clutch slipping? New clutch on the way, and I purchased a second Raptor 700 for my wife.

I had the chance to ride and tune both bike before making my decision on my second bike. I was thinking if the 450 is faster, I will by a 450 and my wife can have the 700. She does not ride as hard as I do, and she does not care. I bought the Raptor 700 not for what it is when you buy it, but what it can be. Nobody that wants to go fast leaves anything stock so the stock number mean nothing to me. The 734 kit is the best bang for the buck $540 just do it. If you think a pipe,jetting and intake is a big difference, this lit is about twice that. I used the 10.75 to 1 pistion, I did not want to mess with the race gas, so I probably left 3 hp on the table, no biggie.

I hope this helps some people, you can't go wrong with either bike, But the Raptor is going to be one hell of a open class desert racer and king of the hill where I ride. Just wait till some aftermarket cams come out, this engine is just begging for a little more RPM capability.

PS. I measured the valves, 20 degree valve angle with 2 (1.5inch intake,) and 2 (1.25 inch exhaust), This is a lot of valve area. The number of valves does not matter, it is valve area and angle that counts.

Yamaha is making some very nice machines.

Have fun, ride safe.

 

AWESOME WRITEUP!!! That is what I have been wanting to see! Good job! I dont doubt for a minute that the build potential on the 700 is far better than the 450! Thats pretty impressive results! The lady is riding our 700, and I am looking at the 06 450, just cause I want a nice lite weight, agile machine that is pretty dang fast for the buck. Seems to me you pay a lot more to make a 700 faster than a yfz. But I new it could be done! To me, the extra power on a bulit machine doesnt compare to the handling and track worthiness of the yfz. That is why I am going that route. Plus, a big reason the 700 or the 734 are SO awesome in the sand is because of the MASSIVE TORQUE! Put them in dirt and the 700/734 wont shine AS much IMO compared to the yfz.
Thats awesome though.....good read!

 

I agree,

You will spend more on the Raptor no doubt.

If you pipe, intake, and jet both machines, the Raptor will cost you an additional $260 for the Powercommander where the 450 cost $20 to jet. Shocks are a big expense, the 450 handles great with the factory hardware, A little stiff for me (I don't jump the machine 10 ft in the air, so I like a softer ride). My Raptor felt a little skittish with the skat trak mohawk fronts on it when pushing hard through corners. I thought it might be the tires untill I added the ELKA shocks up front, they completely eliminated the oversteer or erattic feel when the bike was loaded at speed in a corner. I think the new shocks keep the tires on the sand or dirt much better unstead of bouncing from one top to the next.

The YFZ450 out of the box never gave me this feeling and was very well ballenced once the sand stars were removed. I think the angled paddle tires have a tendency to "screw" themselves into the sand when both tire are not in contact with the ground causing the rear to move side to side under power. We thought the rebound was too stiff at first untill we changed tires. I had to work harder to do the same thing riding the Raptor with the stock shocks. The 450 takes less work to ride hard, and seems to be able to put power to the ground coming out of corners without blowing the tires off for some reason.


I might get the new rear shock before this weekend. If I get it, I am going back to glamis and try it out. I try to test at least on item or change everytime I go riding. Improvement is allways fun.

Ride safe.

 

Bump

 

here is my 2007 SE edition, it has a Nmotion pipe dyno jet programmer, pro intake, and lid, labor day weekend at little sahara one of the guys in our group has a new 2007 450 with pipe and filter, not once in four days did he win a race up the hill.
