HI,
Has anyone changed springs, revalved or both. I want to talk to anyone who has.

I just bought a '00 WR400. Even after backing off all the compression setting to minimum it's still to stiff for an old guy like me. I'm looking for a plush ride through the rough rocks and whoops of SW Idaho.

If you have softened you suspension let me know what changes you made, how you ride and how you like the result of your work and expense.

Jerry,

Do a search using the user name "Bryan Bosch" or the post, "Where to get my forks/shock re-worked?"

You will get some recommendations for different suspension tuners in the US.

I'd skip Pro Action on the forks. Don't believe their advertisements. Follow Bill's advice.

the 98 & 99 models came with softer springs both front & rear. i wouldn't think you'll have any trouble getting them off the lads on this site if you want them.

Thanks Taffy!

Does anyone have OEM springs for 98 or 99 WR400FM that they want to sell?

If so do you know the spring rates for them?

Jerry, I too thought the fork was a little harsh for rocks/woods. I had MX-tech revalve them last month--can't say enogh about how this improved handling. The bike feels much lighter. Big hits don't deflect the front end anymore. I ride 75% Eastern trails, 25% light MX (no big jumps).

My advice is you choose to revalve is to choose a shop that does both MX and trail setups. The pure MX shops won't know what you need.

BTW, I did not require new springs on my '00. I'm 195 + gear+ mud buildup :)

If you're a suspension idiot like me, have them revalved. Otherwise search on posts by James Dean, he has modified his shim stack (similar to what a shop would do) to remove some mid-range harshness.

Good luck

Hi Jerry, I am also in the over 50s trail riding group and faced the same problem. My first fix was to change to Redline "Like Water" fork oil. This actually worked well. Over the Chrismas break -too hot to ride here- I took out the bottom shim stack and opened up the compression adjustment valve. didn't do what I wanted so I removed 5 of the 11 shims from the stacks. I also replaced the stopper washer with a small shim that had a smaller outside diameter, just enough to protect the alloy body- this allows a larger peak flow. The effect is to let the forks soak up the small hard hits that would ortherwise deflect them and jar our old bodies. I didn't touch the other stacks so bottoming isn't really a problem. The local Rece-tech guy does something similar for older riders. The Racetech valves will give enough adjustment to get close to my set-up but these youngsters really don't understand what soft damping means so be fussy if you get a shop to help. Regards from Harry
