That best place to start would be to perform the procedure that Andy mentions in his video about checking the front main spring. Do you remember from the video? This will take two people to accomplish. You need to see how much the front spring is being compressed. That is the best place to start.

Ok yea I'll get those numbers for you tonight. Thanks!

front

eye to eye with frame @ 8.5" = 15"
eye to eye with frame @ 1.5" = 11.375

main spring with me on it = 7"
main spring completely unloaded and off the shock = 8"

notes: with the front end hanging with the preload adjuster unscrewed there is still preload on the main spring. i have no idea if this is correct or not but i would guess its not. otherwise whats the point of the tender spring?

REAR

eye to eye with frame @ 8.5" = 14.3125
eye to eye with frame @ 1.5" = 11.4375

Hey Dem, since you are running an XC setup, you need to measure the eye to eye @ 12" off the ground instead of 8.5". The 8.5" measurement is for TT and flat track.
As far as your front spring measurement, I think you need to call Drew Cox @ Maul tech and ask him how much the front main spring should compress for an XC bike. My conversations with Andy were based on mx setup, so I'm not sure if the compressed dimension of the main spring would be the same or not. I'm sure he should be able to tell you, then you'll know whether it is the correct lb main spring or not.
As far as the symptoms that you mentioned having with your front shocks, they could be caused by any of the following/or a combination:
1. Rebound set too fast
2. main spring too heavy
3. Crossover height incorrect
4. Shock valving incorrect

Hope this helps.
