Just a little tip for those of you who do your own work. The X-brace that runs just behind the fuel tank is mounted to the frame with 4 5/16x3/4"-18 pitch bolts. These bolts are grade five with red loctite on the threads. If you want to remove these, make sure to either heat the thread area, or possibly apply some Kroil, or Hoppe's (gun cleaner) to soften the loctite. If not, the bolt will snap flush with the frame. Once removed, you can clean the frame with a tap, and install some grade 8 bolts which are 1/4" longer. The added length is there because you can now install lock-washers, and use blue loctite. Then if you ever need them out, they'll be much easier to remove, and much stronger supporting your frame. If you do snap one off, an E-Z out probably won't help you. If you are very careful, drill exact center. Then follow up with a .246 piloted ream. Once that is through, you can chase the rest with a tap. Do this at your own risk. It's always a great idea to periodically check the hardware on your machine for security.
