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.
