Updates to show reinforced swingarm, side struts, and rear fairing mounting stalks.  The added reinforcements to the swingarm are  made from sections of the 1" x 2" tubing.  The stiffeners at the front have to clear the links and the pivot (rocker arm?).  The side struts are added to ensure the subframe is strong enough to resist the spring forces and support the rear fairing.  There are two "horns" sticking out the side which will support the rear fairing mounts.

Here you can see the stalks at the side of the new struts that will support the rear fairing.    The top view shows the set screw collars which I had to make as they aren't available locally.  They are welded to the swingarm as well as to the stiffeners at the front.  Everything is now tacked in place.  The next step is to strip down the frame, finish the welding, sandblast, and repaint when the weather permits.

Looking great Tom!! You are among several people I know that are adding rear suspension to their Bonneville racers before next year. You have started a trend!

Tom, did you get the welding finished?  It was warm enough to blast up our way!

Frank,
Funny you should ask.  I finished welding a couple of days ago, cleaned off as much of the old paint as possible with paint remover, and just got done sandblasting.  Not much fun in freezing weather with a Princess Auto (think Harbor Freight) sandblaster and cheap hood, but it does the job.

Painted and reassembled but I ran out of black so --- had to use some leftover orange from my first road racer for the swingarm parts because I couldn't afford gold plating.    Off to Colorado for Christmas with the grandkids, so final reassembly with motor, and adding a new battery box will have to wait.  Here are a few photos:

I have now completed the fitting of the fairings, but no without a lot of trimming of the additional frame members that I managed to get about an eighth inch too high.  I had to actually cut off the tops of both new struts and weld in patches to get the rear fairing fitted properly.  For some reason, four of the rear fairing mounts had to be re-positioned in order to be able to get the Dzus fasteners to engage easily (more-or-less!)

Rear view showing rear wheel clearance to tail. I'll be able to extend the fairing by 3-4" to stay within the 10" rule.
