I have a stripped out fork cover bolt on a 08 yz250f and i found on rocky mountain a tusk thread repair kit and they have a couple sizes to choose from and I'm not sure what it is. The choices are: M5) 5mm x .8mm thread pitch M6) 6mm x 1.0mm thread pitch M8) 8mm x 1.25 thread pitch Its a 8mm bolt but im not sure the thread pitch since i dont have a thread gauge which i was assuming was the length in between the threads, but not sure! So does anyone know what size i would need in the kit or explain what the different sizes in the choices represent.? the kit gives you a drill bit to drill damaged threads out and a tap to make new ones to thread in a heli coil for the original bolt. -Any help appreciated Thanks!
