If you want, we are having a rally in central Illinois on May 14-16 to do the Dremel fix on another bike. We (meaning you) could do yours at the same time! If you don't want to go that far, it's a 5 to 6-hour job for a newbie with some mechanical know-how and the proper tools. No real garage needed. I have a carport, where I have done it several times (just finished one last night).
As for the carbs, if you're getting that kind of mpg, I'd just leave 'em right where they are! Unless you are having issues with them, it sounds like you're doing quite good!
