Un-restricting my ninja 650r

Hey guys!
Just thought i would start a new post about my 2009 ninja 650rl, As i am not getting over the power of it and want to un-restrict it! I am told on the 2009 model it is just the simple removal of a small grub screw located above the throttle, I have found the screw but having trouble trying to undo it! all the star key set`s at home and at work do not fit! So im thinking it may be a one off size or something any help would be great! Cheers guys safe riding!
