I too had the same problem toward the end of running just my first battery pack. When I rotated each tire in the same direction, I noticed that they got "tight" at one spot during each full rotation. I removed the spur gear cover and I checked my pinion and spur very carefully, but they were fine with no missing teeth. Apparently, the mesh was misaligned at the same spot during each rotation. There was no dirt or stone causing the problem.
Just to be sure my motor was ok, I too removed it, hooked up a battery pack, and ran it in both directions with no abnormality.
Then, I removed the spur and disassebled the slipper, but found no problems with the slipper. You wonder where I am going here, right?
Well, I found that while tightening the slipper nut against the spur gear, I had to make absolutely sure that the spur gear was on straight. Otherwise, I'd induce a very slight wobble while the spur was turning. This then screwed up my gear mesh, and caused a "click" when the mesh got too tight.
I have no idea why this should occur, unless some slop exists with the fitting of the spur gear. Since then, I only ran the Slash for 30 seconds to test it, but everything was fine. I will report back after another full pack...
