axle nut help

I bought a lonestar racing axle nut and the thing just wont stay on. I put locktight on it and it still wont stay tight. I want to know what you guys think is the best locknut and if any one has any experience with the duncan racing locknut. I would also like to know if any one makes a antifade for a yamaha because I only sea them for hondas and cannondales. Thanks any help is appreciated.

c'mon on guys any other
