I have an MXZ 500 2001 and it has the HPG Racing shocks on it, I adjusted them way down last winter for more ski pressure but i didn't like it. well the other day i was adjusting them back to the top when one side is stuck at the 2.5 mark and the other is stuck at the 2 mark and either of them won't budge up or down fro anything! I tried lifting the sled and having someone turn on it, let it sit in my warm garage and try it, jb-80, groovy, and nothing works! am i just that weak? i need these adjusted before the big snowstorm tomorrow, please help! thanx!
