I finally measured my spring. My seat is fully sprung. I have the standard AVO spring it measures 160mm when on the stand. (it has a lot of preload) The same when sitting on the ground. 155mm with me on the seat 220 lbs. I have it adjusted this way because most often I do have Allyson as passenger. 133mm with me and Allyson on the the seat. Total weight about 390 lbs. The ride was comfortable but sometimes on really big bumps especially with luggage the shock would bottom On the last long trip I broke a few spokes so before our next trip in a few weeks I am going to install the stronger spring.
Once I do that I will measure it again. I expect it is going to be better for two up. Hopefully it will also be OK for solo. I might even be able to run with slightly more sag and have less chance of bottoming, that's what I hope. Probably it won't be as good for solo but really it is not used that often that way and it matters less then anyway.
My bike has the B RFM, I don't know if that makes much difference. I have the AVO on the front as well and I am very pleased with both. Before that I had a rear Koni and a modified Vincent front shock with the original seat stays.
