2009 crf450 fork valve stack help
Posted 25 July 2011 - 03:42 PM
I decided to take on the task of revalving my own suspension. I have a 2009 CRF450R. I have already upgraded to 0.48 fork springs but still bottom out on hard landings and feels very harsh over braking and acceleration bumps. I am 5' 10", 180lbs, B/intermediate class rider in Canada. The shock feels fine and the stock shock spring is ok for my weight so I am just servicing the rear. Anyone have any advice on how I should modify my fork valve stacks?

What is your low speed adjuster on?

First step to fixing your forks is run a stack close to this for shock
keep rebound the same
after doing the shock run the fork base valve like this and keep mid valve stock
remove 1 of the largest shims, I can't remember the size off hand
also start at 340cc of oil and add more if necessary after riding.
Again, this setup for the forks will only work if you do the shock, with the stock shock stack you will be bottoming a lot on the forks with this setup. Also I would try with and without the rear link, I don't feel the link is needed once the valving is done.

No Cross over?
What was the stock stack?
