I'm taking my 99 MXZ600 to the Bighorns in WY at 9000ft. The dealer says I have to change the springs as well as the weights. Im at 1800ft at home in MN and my Polaris I only needed to change the weights, which is pretty simple. I don't like the idea of having to pay the dealer every time I go to WY. Any idea's? Also, I just put in a 1.5 Camoplast track that rubs a little on the cooler in the tunnel. Dealer says thats ok. Is he right?
