To answer a few questions:
The speedometer is the cheapest one JC Whitney sells (at least at the time I bought it). I bolted it to a piece of steel and bolted the piece of steel to the tank mount. It's the stock speedometer cable. Which is actually how that arrangement came about: I didn't want to deal with replacing the speedo cable, so I moved the speedometer to where the cable would reach it.
The seats were bought off ebay. It took me a while to find the white pillion pad for a price I would pay. I think the front cost me $30, and the rear cost me $20.
I like the tank...but it was a real bugger to work with. The paint refused to come out the same color as the fender/side covers, and positioniing it was a nightmare. It needed to be way forward for the fuel line to clear the frame, but way back to clear the handlebar risers. Solution: Move it back to avoid the handlebars and jack up the back about an inch to make room for the fuel line. Trial and error all over the place with that one.
The other small detail that I like the way it turned out is at the back of the bike. The turn signal stems actually serve as the bolts holding the rear of the sissybar in place. It makes for a nice, neat, tucked in look. Probably my favorite part of the bike, in an odd sort of way.
And yes Vroom, I left the reflectors on
