You will be shocked at how much your speed and control improves just from changing the stock fork springs and getting the oil height set correctly to control bottoming.
This is one thing that bugs me. I weigh less than 135-140 pounds, but one of the first things I did to my bike was get the right springs for me & my lack of ability (okay, so I only had to change the rear).
Spanky, this is not picking on you, it has been bugging me for ages. Everyone should set up the bike for themselves, not just those that weigh more. I'm running GVs, stock fork springs & a 4.4 rear, which works well for me, but is too soft for the guys. After we'd changed the shock spring, myself, my husband and a friend all took the bike for a ride - the conclusion was unanimous - different bike. It was balanced, it handles whoops well (I wouldn't know, I don't handle them well), it handles tree roots etc well too.
My previous bike was set up for a rider the same weight as me (but he had ability) and it was great. Getting on the KDX unbalanced was horrid.
Anyways, the reason for this post is: no matter your ability or weight, sort the suspension out, you will be happy, it really does make a difference.
