[Michigan_Rider]

Working on revalving my RMZ 450. I have the base valve apart and this is what I have.

15-.3 x4

30-2.0

22-.1

23-.1 x 2

24-.1

24-.1 x 2

28-.1

29-.1 x 2

26-.1

29-.1 x 2

20-.1

30-.1 x 6

30-.4

I ride mostly MX, weigh 190 and ride pretty aggressive. Last summer The bike felt ok, but I would like it to ride a little higher in the stroke and soak up choppy terrains.

your base is soft than stock.have you respring your bike?

[karlace]

STD base looks to soft on lsc to hard on hsc.

[cardinale199]

i think 30.4 is not a shim on his valving

[Michigan_Rider]

I had to grind the peen off to remove the nut. I don't think its been revalved or resprung. I got this bike is Aug, the previous owner said he had MCR adjust the clickers and that was all.

[cardinale199]

the mid is stock,the base is mod.the std valving work good work intermediate rider but i think a little spring on fork work much better.i like a 0.48-49 on fork for first,whit your stack ,without a 22x0.1 .pull out that

[Michigan_Rider]

The 30 .4 shim is under the piston. Maybe that will make more sense. Here is the mid valve.

that s the difference from your then stock

your stack is soft then stock

you need 0.49 spring and start with stock valving

make a ride and give a feedback .that s my think

[Michigan_Rider]

I am going to leave the springs alone. My weight changes too much, by spring I will weigh less and by the the middle of summer I will be around 175. I would like to get a stack for riding MX and for an aggressive rider. I tend to land hard on the front and have blown the fork seals on every bike I have ever had. I like the front to feel light and the back to stick to the ground.

Thanks
