'99 WR400 - Suspension Help

I had my suspension (99) done by MX-Tech. The valving and springs are for a 225lb, mid pack "C" mx'er, who does ride rocky trails also. They revalved the bike front and rear, added the later year bottoming cones and went to a heavier rear spring.
The suspension works great and the compression stroke of the forks is much more linear and plush.
Have someone revalve the front and see if that is enough. Before spending on the rear.
99 WR400f, YZ timed, MX-Tech suspension, Scotts steering damper, White Bros E-Series (12 discs), tapered header and a/f. Kouba T-handle for the fuel screw. Works Connection billet throttle tube and frame guards. Cycra Pro-Bend, triple clamp mount handguards. Thumper Racing rad guards, Renthal Jimmy Button highs, YZ Tank and IMS seat, YZ number plate, odo removed, de-octopussed (Thanks Clark) EKP #4, 50PJ, 175MJ, 100PAJ and 65 SJ at 500-1000' Thanks James Dean!

Oh, wait, I AM an American,,, hehe . No really guys listen to what he is saying, her rides on rocky trails. I can see if he is 200 lbs and wants to MX it up, then go stiff. He is saying the bike is bouncing him around, He needs to set the stock suspension soft, not revalve his aftermarket stiff springs.
BTW, my bike is a 99 WR 400. All the free mods (go figure) and stock except for bark busters and a remote hot start .

The Doctor grounded me yesterday afternoon during my annual physical. He didn't like something he saw during the stress test, now Ive got to see a Cardiologist next week for a possible blockage.....I guess I got to close to David.....Anyway gives me time to do some additional maintenance and an upgrade or two....

I agree with you about people just throwing money at the problem and hoping it goes away. My bike is probably one of most stock bikes you'll find performance wise. Only thing I've done is installed a Thumper Racing Quiet core in place of the factory pea shooter. I have spent money on the IMS tank/seat combo because I need every bit of help I can get - and besides, I needed taller/more comfortable seat foam anyways.
I have tried to find a sweet spot within the parameters of the factory valving and I have not been able to. Granted, I have not messed with oil wts or height - primarily because of everybody elses failed attempts on the '99 forks. I'll probably end up buying the parts and doing the work myself with the help of a friend who has done a couple of Gold Valve installs - haven't decided on what to do yet though.
Jason - what is your EXACT fork set-up? Since you seem to think its great maybe I could try it. I'm all for saving the money I'd spend on a revalve.

You better make sure you're healthy. If I have to give you mouth to mouth..... you're gonna die.
What are you pulling the head for? I have a couple spare cylinders. Wanna do a 420 motor?

I to am doing front suspension revalve. I have purchased Race Tech's Delta Valves, instead of the Gold valves... I have one question though... the instructions call for removing some items from the Mid Valve. this apparently is attached to the damping rod assembley. Any ideas on how to hold the rod so I can loosen the nut on the Mid Valve stack.. or does the rod come out of the assembley and if it does how does it get removed... screws out or what... Or can I skip the Mid Valve step and just install the Delta Valves... My goal is to get more compliance and sensitivity over rocks and roots as I am getting bounced off and deflected off with the stock suspension.. I am currently running Race tech springs .43'
s with one preload washer.. 2.5 wt oil at 135 mm height and compression at soft.. still getting deflection on my enduros... any advice would be appreciated.

I would also recommend skipping the Delta valve and try the Gold valves instead.

When (or *if*) you get the Gold Valves (get Type One GV's), e-mail me and I'll recommend a valve stack. RT's stacks are virtually always too stiff on the high speed stack and sometimes too soft on the low speed stack.

Thanks for the heads up on the Delta Valves. Strange, but when I got my Delta Kit, I disassembled the forks, less seals of course. and low and behold, the Mid Valve parts in the kit were missing.. I called Race Tech, this was a mistake... they either did not believe I bought the product or were to lazy to secure a kit to tell me what I needed.. anyway... installation is on hold. My dealer has ordered me a new kit. but with the information you indicate.. I will go with the Gold Valves... Im currently running the Gold Valve in my Rear Shock... Works great... just need to balance the bike and get the front end working..
MX.. I live in Gadsden, AL and ride in the Vet C Class.... I will let you know when my GV kit arrives... and check back with you on the stack configuration... and thanks..

Can the Mid Valve be disabled and still be used with the base valve with good results?? If so.. what is the steps needed to disable...
thanks for the help..

This requires the cartridge being disassembled fully to expose the rebound piston.
