Here is a link on Hypertuning an EQ-6 which ought to be pretty similar: Hypertune EQ-6

I went ahead and took mine apart yesterday, cleaning it all up and repacked the bearings. Here's what I found- if you use the gear set/adjustment screw(front back) you're going to spend a TON of time trying to get the gearlash set.I literally spend two hours on my dec axis and couldn't get it right using the set screws. I backed both screws off, and evenly put a **slight** amount of pressure onto the cover mating the gears and locked it down using the 4-5mm bolts. It's super, super quiet and slews unbelievably smoothly.. that rattly sound that seems to be inherent to the Atlas mount is gone on both axis.
I don't have any graphs or hard data to show you before and after, but can tell you that I struggled to get 5 minute guided exposures without oblong stars before I did this... after, I took a 5.. 6.. 7..8.. and 10 minute test shot last night with perfectly round stars. What an amazing difference.It cost me a can of parts cleaner and a tube of grease...

Has anyone hypertuned their Atlas mount? I'm considering the procedure, but am unsure if it's worth the cost.
Depends. What's wrong with the mount as it is?

One thing I did notice and forgot to mention is how inconsistently the stock bearings were greased. To my surprise, some were well greased while others were almost dry. Also, there were flakes of something(paint, perhaps?) stuck in the gears that was a pain to get out.
Do you also have a lot of slop in your mount?
