Bought from a buddy for $1300 Sept. 2011, sat in garage since 2000, he supposedly put new pistons in it and then couldn't get it started. I went through it all and found it was a bad connection from the stator, had low compression on mag side, turned out to be a stuck ring, freed it up and now have 110 and 100psi mag. I think buddy might have honed off the nikasil? Still seams to run good though.
1997 Arctic Cat ZR 580 (Green)
Made a custom 11" tunnel extension out of pieces I cut from powder extreme donor, rivited them on and re in forced it all, as well as fabbed in some runner extension. Polished top of extension, want to make some tie down brackets too. Also fibreglasses the back of the hood where a crack was starting.
Put skid and track from a 1996 powder extreme under it, 136" X 1.6" Had to make drop brackets and drill new holes to mount from of skid, lots of effort.
