Does anyone have any tips for removing stock riser (8mx1.25) cap screws without breaking them? I have a 2005 bike, and I trying to remove the top two to mount a tachometer bracket with longer screws. Also, is A2-70 stainless an acceptable material for those longer screws? I am worried that it isn't strong enough, and have been told by the bracket manufacturer that I should use "grade 8" or better. I think the A2-70 is a good bit less strong than standard "grade 8". Thanks for all help!
