Either way zorro, you will need to pull the pan to do the work as it will make it easier to work on.. Im more then willing to help you, Just let me know. Options are Heli coil, new pan, or spark plug kit shitty was talking about. By the way, the idea with the washers is that you may have some threads in the pan that are still good and the washers will compress a bit to provide a tight fit for the remaining threads.. DONT TAKE THE CHANCE WITH WASHERS.. DO IT RIGHT.. that last thing you want is for it to let go when your riding.
