I picked up a nice kartboy shift knob about 4 months ago to go with my kartboy short shifter. It seems as if all the threads inside the knob are totaly worn off. I put the stock shift knob back on tonight without any issues and I inspected the threads on the ss and I didnt see any damage. I must have stripped it by overtightening it, but I didnt think I put it on that hard. I did a search and didnt find any people with the same problem. Was I supposed to use some sort of locktight? Maybe I got shipped the wrong shift knob? Help me out here!
