2004 WR450 eval
Posted November 10, 2003 - 10:01 AM
*very* brief eval. All opinions are mine and mine alone.
If you don't agree, fine.
My previous ride (and I still have it) is an '01 YZ426F. It
will be referred to forthwith as the YZ. The 04 WR450F will
be referred to as the WR.
After trying to start it on Friday night with little luck,
I tried again on Saturday morning. After the all to familiar
pops and sputters, I realized that it likely had a fouled
plug. I attribute this to looky-loo right hands as the bike
sat on the showroom floor for about a week while the previous
potential owner decided if he wanted to buy or not. Anyway,
after installing a fresh plug, it fired up with the use of
the kickstarter. The bike has had the snorkel removed,
grey wire cut and throttle stop fixed.
Yesterday, I took both the WR and the YZ to the local MX
track. After the required breakin time, I took the WR
out to wring it out a little. I have a total of 16 miles
on the bike. Here's what I thought:
1) It's underpowered as is, compared to the YZ. This might
be a blessing for trail work. I think opening up the airbox
with some well placed 1" holes will help. Time will tell.
I don't expect bikes to perform at their optimum out of the
box. I always have the YZ cam option so I'm not worried.
2) It jumps as well as the YZ.
3) The tank/seat junction is FLAT! I jumped forward as far
as I could at one point to make a turn and pounded the boyz
into the gas cap.
4) It seemed to turn just as well as the YZ.
5) The bars seem a little weird to me. I have PT's on the
YZ and that's probably the difference.
6) Shifting and clutch work is a notch above the YZ.
7) The suspension seems to work really well. It's impossible
to tell with this few miles on the bike though. I've been
impressed with other WR's suspension though. I have high
hopes for the future, once it's broken in.
8) It doesn't start worth a crap when cold with the button.
9) The jetting seemed to be close. I don't even know what
jetting is in the bike. I was told it was still stock, but
am not 100% sure. If it is, I'm sure it can be improved
as I live at 6000 feet.
All in all, I think it's going to be a good race bike. I
have to get it dialed in for my riding style. Mods coming
include PT's, setup for my Scott's, handguards, and a
skid plate. Examining the underside of my YZ revealed that
a skid plate is needed.

I just picked my 04 WR450 up two weeks ago. The new manual shows the jetting has changed from the 03's.
We are running a richer jet needle and a larger main (165) in stock form. The pilot is a 45 like you stated.
I have removed the airbox inlet restrictor, throttle stop shortened, pipe butt plug and richened the low speed to 3 turns out from closed. The bike cold cranks right now if I follow a certain procedure. Just pull out the choke, blip the throttle two times, count to 10, then hit the magic button. It starts instantly. The jetting seems to be perfect on low end. I pulled the plug after a fast run and it's a tad on the lean side. I am thinking about lowering the needle clip down one notch and trying that. And possibly going to a larger main, like a 170.
I'm in Florida, close to sealevel. So our jetting should be close if our mods are the same, don't you think? I haven't unplugged the grey wire, for I do a lot of tight stuff and I feel that the powerband is perfect right now.
Just thought I'd say hi. I am new to this forum.

I took it out for a quick 45 miler a couple weeks ago. The
motor broke in a little and woke up somewhat, but it's still
a little tame. I still like the way it turns, handles, and
the suspension seems to be pretty good. I wouldn't/couldn't
stretch it out in the woods as I don't have any handguards
yet. Waiting on the PT's and it's amazing how much you use
the handguards to fend off stuff...
I'm gradually getting it dialed-in. Recieved the WB 1"
air intakes but haven't gotten them installed. The weather
was just too nice to work on bikes so I took the YZ MXing
To whoever suggested the JD kit... I'll probabl do that!
I met JD this year and he's a really nice guy. I've heard
nothing but good things about his kits too...

I did order some Works Connection frame guards. And right on the package it says they won't fit 2004 models. Geeezzz!
I guess I'll check them out and see if they can be modified to fit anyway. But if not I'll have some frame guards for sale!
I was looking at the manual last night on changing oil. Wow!
There's like 6 plugs you got to remove, top skid pan, hoses and screens, oh my! LOL! Sure seems like a lot of messing around just to extract a little over a quart of oil!

Cleaning the oil line screen every season makes sense.
And yes, oil is a explosive subject for sure! But like you, I believe in synthetic, and have for many years. My ole Chevy pickup has 300,000 miles on her to prove it! Never had the heads, valve covers, or pan removed.
Just need to make sure the additives won't harm the clutch plates.
I'll let you know why the guards don't fit an 04 later.

Just thought I'd pass this info. on for you and the other readers.
