Didn't want to put this post in the general suspension topic, since I would like feedback from other 10/11 YZ owners - I am curious about the quality of the OEM fork springs, more specific the accuracy of the 0.47kg stock spring rate and the tendency to lose some of the spring force after time. Seems my YZ worked great when new, and now it tends to feel like the front end is softer compared to when it was new. Not so much of a damping difference, but maybe more sag. Has anybone measured the stock spring rate after say 50+ hours? How about recommendations for aftermarket springs, any difference between quality of springs from Factory Connection, Race Tech, etc? Thanks for any input.
