So my buddy has an 03 YZ with some really stiff springs and way too hard for his little 165lb girly frame. Just too much for him. I have stock springs in my 05WR and they are way to spongy for my 250lb all man frame. Can we swap the springs from bike to bike? Additional info: The 03 YZ springs are from Race Tech and set up for the original owner, he weighed about 200lb's. I know that less than me, but can the springs still be swapped from YZ to WR and vise-versa?
