Well I knew it would happen. After 2 months of riding I want to modify my sled. The riding we do here is strictly deep powder mountain riding. My 96 EXT 580 needs help in the4 floatation dept. Currently it has the cat 1.4 track. I know I need a 2 inch - I am wondering what else I can do (besides sell it) to enhance its deep powder capabilities. What are the benefits of aftermarket tunnels? If I added a 3 inch drop kit to the back would I have to move the front down an equal amount? what about a roller secondary? Has anyone piped the 580 efi and had success? Thanks!
