The rear shock on my 03 9R has gotten super soft and bouncy in the last few days. It seems to ride fine still, but on bumps of any girth it continues to bounce a few times instead of stopping and riding on.
I need to pop off the seat and take a look at it to see that everything is OK, but havent seen any oil or anything around.

Suggestions?

If the shock is "bouncy", and adjusting the rebound does nothing, the shock is probably bad. Look at the shock and see if there is oil leaking around the shaft. If so it is bad.

If the rear has gone bouncy . . . probably needs a rebuild. The rear shock is a gas shock so . . . it may never show signs of leaking oil but lose its charge (no oil seen can be that the remote is leaking air)
. Most shops can refill a shock relatively cheap. But it will most likely begin to leak again because you probably have an issue with your seals. Thus a rebuild is in order.

I have found that some folks shy away from the rebuilding of their own forks and shocks. The process isn't difficult but tedious and messy. If you decide to go the rebuild route there are several pdf's on how to do it. Just like the forks . . . take your time. The internal parts can easily be damaged, defeating the entire rebuild.

But being that rebuilds cost money and take time, I did happen across an ebay auction for a shock from a XB9R . . . Item number: 380064571503 on ebay. (see you have already found a new shock in the classified.)

I happen to do my own suspension from years of riding offroad. On my STT, I have redone my forks to my liking (springs/oil/stock valves). I have foundn't a reason to change my rear shock though. So in your query I did a little research. the Showa rear shock on the XBs is similar to other Showa Shocks. The process is long but rather simple. If you do just replace the shock . . . I would put aside the blown shock for later. One day take a crack at it. Knowing how a shock or fork works will always help you understand how to better adjust your suspension. Good luck with whatever route you take.

If you haven't changed anything, definitely reset your suspension settings.

On my Cityx 2 things happen. I find my suspension setting change ever so slightly on their own. Last time it happened I marked the set screw positions, and few weeks later they had moved slightly.

The other issue is weather. I am also a lightweight (170 with full gear), and I find the oil viscosity quite sensitive to temperature.
On a cold day without a lot of extra weight on the bike I have to back off the compression setting to avoid being beaten to death.

A lot of people are not nearly as sensitive to this stuff as I am, so your YMMV.

I'll tear into this one later maybe. Picked up another off an 06 for a good price.
I'll have to mark my settings on it and see if it moves too.
