First Trail Day on the New WR450F.....
Posted February 07, 2009 - 04:48 PM
the trails. After removing the AIS and rejetting the bike,
I hit the trails today. The power was much more containable
then I expected. In fact, probably so much that my
concerns for opening up the intake and exhaust are much
less. Not sure Im going to do it quite yet, but Im not
real worried about it now either.
The bikes power was very consistent across the rpm range.
I didnt experience any "hard hits" in power that would
catch me off guard. Suspension needs a bit of dialing in,
but not too bad. Especially coming off the WRR. Im still
not real clear on all the posting about chaning the shock
spring. Last night, in preperation for today, I checked the
sag numbers, and everything seemed inline. I made a "very"
small adjustment in spring tension, but otherwise my sag
numbers were consistent with what would be expected.
Rider Sag was 108
Free Sag was 44
I know the free sag isnt quite as close to the "middle" as I
would have like to see, but still within "tolorances" so to speak.
Anybody else want to chime in on this?

I now have 20mm static to 100 race.
Much better IMO.
That and some rebound, high speed compression adjustment has eliminated my rear end kick. Super plush on the rocks and roots.
ln the forks I went up a rate from 0.46 to 0.48 and raised the oil level. Much improved
I weigh somewhere in the 190+ range naked and race Senior A in hare scrambles. Our HS's are quite tight and gnarly mind you so in a faster riding arena- desert- might be different.
I do ride the MX track ocassionally and don't have any problems with bottoming though I'm not hitting the big doubles and triples

Did you replace it?
ABSOLUTELY.....I didnt buy a bike to only get 1/3 to 1/2 throttle.

is there a throttle stop on a 2008 wr450???
Yep, unfortunatley there is.

The GYTR kit takes care those problems for a pretty cheap price though.
Not too bad of a price.
One thing I hadnt noticed though, is that even the instructions
tell you to remove the pea shooter from the exhaust, and open
the air intake up.
So for those of you that said I wouldnt make it a full season
before opening that up.....Well, you were right.

I did the GYTR kit and WOW! what a beast. All free mods and that's it. No exhaust, no performance mods ecept for the adjustable fuel mixture screw.
Then I got the 08 and never even rode it till I had all the free mods and GYTR kit installed.
Still to this day, both my WR's have the same mods and no aftermarket exhaust at all. It's true "A Beast Can Be Tammed" Lowered the forks so they corner better on slower more technical rides. High speed desert not for me. The faster you ride the more it hurts when you get off.
I will say this, never did the suspension on either bike..... and they need it badly!. Too spongy, front end bottoms out right now.
