I went to a .48 front 7.5wt. oil, 5.8 rear. The front is a Factory Connection, the rear is a Race Tech, it works ok for me and my riding area/skills/age and weight 215 without gear! -- some people re-valve -- some people put yz forks on -- the list goes on depending on the money you want to spend and your needs/riding type etc. Check out the suspension forum:ride:

HOW HARD IS IT TO CHANGE THE FORK SPRINGS ON 08 WR 450. DO I HAVE TO TAKE THE FORKS OFF DO I HAVE EMPTY ALL THE FLUID OR DO I JUST UNSCREW THE CAPS AND PULL THEM OUT OR WHAT. ALSO DO I NEED A SPECIAL TOOL FOR THE FORK CAPS
Check your Owners manual, it explains it all.
In essence, I think no, you should be able to collapse the forks in the bike enough to extract the springs without pulling them apart or draining the oil. Do it slowly so you don't bring too much oil out with the spring.
(Also, just be careful the bike doesn't drop in a big hurry and damage something! think about it before you start.)
All you'll need is a socket for the fork cap itself ( i think 22mm from memory) and an open ended spanner (I think 19mm) to hold the nut on the damper rod. Plus of course a 12mm socket to loosen the upper triple clamp bolts to reduce the pressure on the top of the fork tube as you undo the cap.
The hard part might be checking the oil level after the springs are out. It's better if the forks are perfectly vertical when checking this.

If you still have the stock oil in them, change that ASAP! Getting rid of the stock "fish oil" made a big difference in my forks.
X2-You'll be happy you did.

Out of curiosity, can you see the valving/piston with the springs and fork oil removed?
No you have to remove the bottom cartridge.

No, I think there is a better description of the substance Yamaha sees fit to put in their WR450F forks....
It's not exactly an oil, I'd describe it as a tacky chain lube for the forks!
It's all stringy, just like bloody chain lube! What the ??
