My 2 cents:From day one, the OEM rear shocks were inadequate for two-up and gear. I replaced them with a pair of S.& W. air shocks. With a “passenger” and no air PSI the S. & W.’s were too hard. I haven’t had a “passenger” for years so went to these:
I found these to be too hard! I took them apart. The nitrogen cannister has a bladder that separates the gas from the oil but the gas volume is so little; I found it useless for its purpose. I removed the bladder and most of the oil. They are installed with a cross-over and gauge. With a small bit of spring pre-load and 20 PSI the ride is compliant and comfortable!
Front shocks; 20W oil, 24PSI (on the center-stand) with a gauge and cross-over. The front still dives with a firm application but is acceptable for myself. A note here: I’ve been riding with 24 PSI for YEARS (?) and have never “blown” a seal!
(There’s a joke there but I’m not going to elaborate !!!)
