I had my motorcycle in for major maintenance a couple weeks ago. They are
supposed to go over everything.
Anyway, I decided to check my chain slack today ... the manufacturer's range
is 3/4-inch to 1-1/4-inch. It is right at 1-1/4. I decided to leave it
alone.
Anyway, I was walking back in my apartment, and I thought, well, why not
just be sure the axle nut was tight, since I had the torque wrench already
out? ... so I set the clicker to 65 ft-lbs and, much to my surprise, I had
to rotate the axle nut nearly 1/4-turn to get the torque.
That should not happen. I always torque it to 65 when I adjust the chain,
so either it came loose on its own or someone loosened it.
The only thing I can figure is that the dealership adjusted the chain slack
or inspected something else when it was in for major maintenance and didn't
torque it back to the manufacturer's spec.
Are there any other plausible explanations or anything else I should
consider?
I might call the dealership to find out if they had the nut loose or off for
any reason ... if yes, I'd be satisfiied that that is the cause.
There is nothing compressible in there and just too much material in the
axle ... I don't think I need to investigate further, right?

Isn't there a castellated nut with a cotter pin
to hold it in place?

The nut has two wing-like features (don't know what they are called) towards
the end of the axle that give it more friction so that it won't vibrate
loose. There is no provision for a cotter pin.
I have seen both approaches on axles (so I know what a castellated nut is).
Mine is not a castellated nut. But I don't know the right word for what it
is.

Self-locking nuts do wear out, yannow.
Spend the $6.00 on a new one and feel secure about its self-locking
properties...

I have never, ever had a rear wheel nut "wear out".
Not in 35 years and about 300 motorcycles.
