Hi Shane,
Early this year i replaced the plastic gears in my 12inch LX200 with bucks gears which also includes the tune up instructions you will recieve, my scope benifited greatly from this upgrade as the plastic gears were only 80% meshed on the RA and DEC gears and the dec worm gears were not meshing well and the backlash was huge. Now i have 100% mesh on both the RA and DEC gears and the DEC worm gears are now meshing better.
There was a strange knocking sound at first after the bucks gears upgrade and tune up in both the RA and DEC drives which was not present when slewing but started when sidereal tracking started, it settled down after 10 to 20 seconds of tracking, after researching information on the meade lx200gps yahoo group about this noise i found i also needed to upgrade the RA and DEC tension springs with a slightly heavier gauge spring, this is common for some 12 or 14 inch LX200s,* it now works very well.
I am also just starting to use autoguiding while imaging and will be doing PEC training soon for my setup, but i use alt/az setup with a meade de-rotator not a wedge so from my research PEC training for me will require a slightly different setup.
The bucks gears instructions are very easy to follow and you will benifit from knowing you have adjusted it as best as is possible, and also given the scope gears a regrease as well.
