2-up spring weights
For my Ryker 900 original spring, I had it set at 5 (max) because I was going to ride once in a while with a passenger. I had the Ryker 2-up spring installed, and the dealer set it at 3. Does anyone know what the weight limits are for the stock spring compared with the 2-up one? Should I have ALSO set the 2-up spring to the max (5)? I can't seem to find weight suggestions for the 2-up spring. The stock one is in the manual though.

Did you notice any improvement between the stock and 2 springs. I am thinking about the 2 up or the Fox rear spring. I have the 900 ace.

A spring is set correctly when the suspension settles by no more than 1/3 of its travel with the rider or riders seated.
1) Have someone lift the rear of the seat, or use a jack, to fully extend the suspension.
2) Measure the vertical distance from the top of the tire to the underside of the passenger seat/max mount.
3) On a standard Ryker the rear suspension travel is around 5" - 1/3 of this is about 1 3/4"
4) Seat rider and take the new measurement distance - it should be around 1 3/4" less than the previous measurement.. Adjust preload to correct this measurement.
5) If carrying a passenger seat both rider and passenger and again adjust the preload so that the suspension compression is about 1 3/4" less than the fully extended distance.
Yes, it could take three people to check this, but it works and is accurate.
This works for any motorcycle, two or three wheels.

I jacked up my 900 Ace that had the 2 up spring installed and I have slightly over 6 1/2 in between the bottom of the max mount and the top of the fender so it would likely be over 7 in to the top of the tire. I adjusted the shock so that when I am on it I have about 2/3rds of that amount. Not sure if the 2 up spring adds any static height but your measurements seem off at 5”.
