Hey, I just bought my first atv, (2000 arctic cat 300 4x4) I got it from an old farmer and it's in pretty rough shape. Iv done a few easy things such as - new battery, oil change, added new fuel etc. It runs, idles, and sounds alright. One of the problems I'm having is it won't drive in either high or super low gear, it will only move in low gear anyone else heard of this issue? Thanks.
