Yes, that's aftermarket. It looks like a Progressive 465.
Those have a 5-position rebound adjustment.
The best way that I've found to set up a rear shock is to (obviously) adjust the spring to the correct sag and then go find a washboardy road.
Since the only adjustment is rebound, you want to set it so that it is exerting just enough control.
If the rebound is set too stiff the shock will 'pack-up'. What that means is that, after taking a hit, it cannot rebound fast enough to recover it's length. Each successive hit compresses the shock some more until the shock becomes quite compressed and the spring won't allow it to compress any more. As that happens the rear end of the bike sits down. Clearly, that creates far less control and removes any ability to take hits without popping your fillings out of your teeth.
On the washboard road (go on out to Carrizo Plain and get on Soda Lake road - great for this and a fun place to ride). Turn the rebound adjustment to fully on. As you ride at a speed that is comfortable for you, you will find that the shock packs up. Back the rebound off one notch and ride again. Keep it up until the shock doesn't pack-up at your speed. It's a crude method, but you only have five positions, and it works.
As skills increase and you begin to ride faster you may find that you have to re-adjust.
There's always a bit of trade-off. At speeds of 25-70mph on washboard roads I don't feel a thing. The bike just floats over bumps. At less than 25mph the ride is pretty harsh. Meh. My set-up is a Cogent shock with RaceTech emulators and Progressive springs in the front.
You're a leg up on most KLRs with that shock. You bike is worthy of some springs and RaceTech emulators, or perhaps the Cogent inserts (heard good things about them, but have no experience with them).
I won't recommend the Intiminators as I found them to be too fiddly and hard to adjust for what I wanted and needed to do.
Tuning the RaceTechs is very simple, but time consuming and a bit messy, as you have to remove the caps, spacers, and springs to fish them out of the fork to make an adjustment. It takes about three tries to get 'em right.
A call to Rick at Cogent Dynamics might be a good idea. He's good people.

On the way downtown I stopped at a bar and had a couple of double Scotches. They didn't do me any good. All they did was make me think of Silver-Wig, and I never saw her again.
'How' are words so important they cannot be too often used.
