After picking up a VN900 seat in the fall, I finally got around to getting it mounted. I figured that with the back wheel already off (getting a new tire mounted), I might as well dive in.
Prior to mounting the seat, I removed the stock side rails. Using the old and "not shiny" set from my older 86 parts bike, I used a band saw and cut off the vertical part, leaving just a nicely curved rail. This allowed me to continue using the F&S saddlebag supports and relocation brackets.
For mounting the new seat, I basically started by setting the seat on the bike, and then working my way back from the front, supporting and attaching it along the way. It wasn't that hard (mostly because of all the tips and tricks I picked up courtesy of the fine folks here on the forums).

At the front, I grabbed a strip of flat metal, bent it, and attached it to the frame above the existing mount. The height was right, but there was some side-to-side play. I marked the edges of the VN900 tongue, then added bolts with extra nuts. Perfect fit!!
Behind the battery, I built up the frame cross member with some PVC pipe. The first layer is just a 1" pipe with a small strip removed. Then, two smaller pieces (one for each end) with a larger strip removed. I heated these pieces with paint stripper to make them easier to spread and "snap" on. Finally, two pieces of 1.5" pipe to finish it off. Some pipe solvent to "glue" the pieces together, then a tie wrap (just in case).
Above the rear fender I marked where the rear supports are, then attached a simple 1/2" tube to the frame.
To hold the seat down, I was able to insert a bolt into one of the holes in the seat (with a short "T" strap to keep it from falling out), then secured it with a washer and nut. Then, the bolt goes down through the hole in the frame, and a washer and nut secure the seat to the frame from the bottom. I had to cut a hole in the fender to install the nut. The bolt doesn't protrude through the fender into the wheel well.
Next winter, I'll take everything apart, paint the new pieces, and sand and polish the cut-up side rails.
I'm also looking for a passenger backrest/luggage rack ... I hear that something from a Honda 1100 should fit !!
