Hi folks, John:
I just insured my 750 Paso for another season after riding my SS for most of the summer.
The rear end is sproingy. When I sit on it, it seems to settle more than it should, and when I jump around on it in the garage, the rear is soft and springy..sproingy. I took it around the block and the rear seems to squirm when accellerating out of turns.
So- The Marzocchi unit has a plastic nut on the side at the bottom. Its not quite as it should be- I think the insert is missing. I can take off the nut and there is a inner fitting that can be screwed in all the way (done). That should firm up whatever that is (compression?) The remote reservoir was set at about 2. I turned it up and there was no force until about 5, then it was harder to turn. I turned it up to 9 of ten and it didnt seem to change anything. The large pair of locking nut adjusters on the top of the shock appear to be threaded about 3/4 of an inch from the top of the threads.
What can somone tell me about how to firm up myrear end? No stairmaster jokes please!

Re: Rear suspension
I have very, very little suspension setting experience, so take this with a grain of salt....pasophist wrote:When I sit on it, it seems to settle more than it should, and when I jump around on it in the garage, the rear is soft and springy..sproingy.
If the rear end is dropping more than you like and is easy to get to push down than you'd like, I'd adjust the preload by adjusting the big spring. Adjusting the preload will effect the "sag" of the rear suspension. If it is bouncy, as in it seems to spring up-and-down when you load the rear with weight and then rapidly remove the weight, I would think it would be a damping issue. I'm not sure, but I don't think you would notice any compression adjustments by sitting still, though.

Re: Rear suspension
The remote reservoir controls the compression damping, and the plastic nut that is missing is for adjusting the rebound damping.
If the setting on the remote reservoir is above "2", and the compression isn't rock hard, then there is a problem.
You can adjust the spring preload by moving the threaded collars at the top of the spring, but if the screw that controls the rebound damping is turned all of the way in (with little or no apparent effect), then all you will have is a higher-riding, springy rear end.
It sounds like you need a re-build, or a new shock!
