I am serious. I was having problems with my hands hurting. I just "felt", somehow, that the grips were too close to me. I took the risers off, noticed the bolts were nasty, and ordered a KB service kit from Murph. I then took the risers off, to see if that made a difference, and it fricken cured my problems! No hand pain! Not even from 600 miles in 36 hours! So... as soon as my "stock" bolts come in from the website I ordered them from, I will clean and package the risers and sell them off. I'm currently using the bolts, even though they are too long. The bolts are the only thing I've used out of the KB Service pack. The covers and set screws are brand new.
