Hi Don, yes that's right. I kept my progressive springs (they work better) in, used some pvc pipe as spacers and cut them down so they just poked the end above the end caps thread and used 5Wt oil.
For Hagon progressive springs, the air gap is 140mm but I would use whatever your progressive spring manufacturer suggests.
You should be right to go then. Thanks for your comments too mate. It's been an interesting trip so far and looking forward to the ride home as well. My bike is just so comfortable now it gets me excited thinking about it.
cheers
