SOURCE: suspension specs for a 2007 yz 125

hi lilsilence, thank you for using fixya. below is a line from dirtrider.com, answered the same question for a 2003 which is the intro for speed sensitive suspension.

Several ways to go here. Remove half of the fluid in each fork and addback a 10wt. This will approximate a 7.5wt. Going to a 10wt. willreduce bottoming but will give you some harshness. Depending on yourweight and riding style it is difficult to give you proper advice, justgeneralities.
I use ATF fluid. I'm valved for wood and light MX, stock springs, and Iweigh 155 lbs. ATF is cheap and is something simular to 7.5wt. I'm noexpert and my explanation might not hold water but it works for me.

Mobil1 Synthetic ATF is a very popular fluid that will probably be the weight you want.

Seems to me that I can make much more difference in the action bychanging the fluid levels. If you mix up riding between track andtrail, you may want to consider sub-tanks.

Draw out half of the fluid with a piece of tubing attached to a saryngeand put back an equal amount of 10wt. Adjust the level from there tosuit your comfort.
Sub-tanks give a greater amount of adjustability and plushness. Pricey but do the trick when properly set up.

http://www.dirtrider.net/forums3/showthread.php?t=159185

I have use close to the same method on my rm250 and have worked for me, i sure hope it will help you out in another way.

if you have other question, please let us know.

regards,

voodoo
