The seat on the left was purchased for cheap, so I decided to give it a try.  It's small size looks cool, but you can see a lot of the wiring and stuff under the seat that the stock seat covers.

I looked at the way this bracketry was online and envisioned a way to fabricate a simple bracket to mount it to the front.  The rear I figured I'd worry about later.

These are the parts I bought to mount the front:  A long bolt and nuts  and a piece of thin bracket metal.  I was able to cut this with tin snips and drill through it easily.

(I did end up hack sawing off the lower part of this front seat bracket to drop the bracket lower --to drop the front of the seat about 3/4"-- so I could bolt through the top set of holes)

This is the bracket I made on the left.  The wire protection tubing was bought for cheap at Auto Zone in the electrical section and hides the wires somewhat.  I zip tied them on.

Now, I bolt the bracket to the frame and my new bolt goes through the seat bracket and the one I made to install.

I messed around with different rubber materials to rest the back seat of the on, as I couldn't find a way to bolt it on.  I figured gravity would do the trick if I had the front of the seat secured.

I was browsing Auto Zone and found this "Bow Stop" for boat trailers.

I shaped the rubber with a saw in this shape so I could insert it along the fender.

The rear of the seat just rests on this piece of rubber, that should not be able to move around.  It runs along the fender and rests on a piece of the frame.  It's sturdy, solid rubber too.

As you can see from the picture, the seat is more rearward than the stock set up and that gives me a more comfortable seating position.  Forward controls are not necessary really now due to the more rearward seating position--somethin g to think about.

I'm not too crazy about the wires showing and not protected, but I'm going on the "it's a chopper, who cares about detail"-attitude on this!

I'm not crazy about all the wires and stuff showing from upclose, or that these parts are more exposed.  But I say, "the hell with it."  I'm not entering any bike shows!

Bottom line on the comfort:  I like it better than stock, primarily due to the rearward position. It's not the most plush seat, but if you want to sit back farther and have a small chopper seat, this one's the ticket.  An added plus is that the metal bracket between the seat and tank makes a great "handle" to hold the bike upright to check the oil.

I made a cover with a small piece of sheet metal.  I fit it to the opening as best I could.  Then I painted all the exposed parts to blend things together.

Bottom line:  it may not be really professional, but the wires are better hidden and protected from the elements with my new cover.

Here's what the parts look like on. 

Note:  I removed my dogbone risers for a more forward seating position.  Between the seat change and the bars back low, I'm really happy with the comfort/ride...for now!
