I have an 02 mxz 600 trail. I am thinking of studding, but was told it is a real pain. I was wondering if I should attempt this myself or take it in and get it done. If I doo it myself i am told i need a special drillbit? Also what about tunnel protectors, what size studs, what kind are best, stud pattern, 96, 144, down the middle, some outside. I know alot of questions, but i am really in the dark on this one. Any help is appreciated, thanks.
