I finally got around to it and locked my front differential yesterday. Had to play with the adjustment a bit and cut the sleeve that the shifter cable comes out to get all three positions. Cut a little too much off and now the cable hangs up a bit, put heatshrink tape on to smooth it up. Tried it out and it is awesome! The steering is OK in 4 wheel lock as long as you are not on hardpack. The shifter has to be in the right position to get 4 wheel limited slip. I marked the fender for the proper position so another rider doesn't screw up the diff. Hope Arctic Cat will listen to us and put locking diffs on all their bikes. They have a good bike in all size classes, with the locking front they would be great.
