How would you fix this...?

[wirehairs]

So the previous owner of my bike drop it at some point, and put some cracks in the fairing support strut.  For the fairing screw mount farthest up the fairing, a piece is missing around the rubber wheel nut.  See the pic.  What do you think I should do?  I'm thinking about just gluing it in place, but here's the deal: I'm installing a Laminar fairing extension, and its mounting bolts fit into this particular screw hole.  The only other thought I have is to replace the allen bolt that comes with the new fairing with a longer one, and drill a hole all the through the plastic on the back side and install a washer and a nut.

What do ya think?

I had this same problem on Jason's '93 I refurbished.
I got a flat piece of  1/4" thick ABS and trimmed  it down to fit behind the damaged area. It got a good purchase on both sides of the damaged hole. Drilled the correct diameter hole for the rubber well nut and then sanded off the paint on the backside of the damaged fairing area then used ABS glue to solvent weld the 2 ABS pieces together. Clamp in place and let sit for 12 hours.
The fairing being ABS and the ABS backing piece essentially becomes one piece with a solvent weld.

I have not had the best luck with ABS glue, but others have so it seems it works in some cases. I bit the bullet and got a plastic welder from Harbor Freight and learned how to remelt the plastic back together. Strong as new and when possible reinforced to be even stronger. If you don't mind the wait, mail it to me and I can fix it.

He will have to send you the whole fairing.....

Even carefully packed, the chances of further damage in transit are 50/50

Oops, I missed that detail, sorry...

You can also weld ABS with a soldering iron and scrap ABS parts. For small jobs I have been known to use this method. Practice this first till you get the technique and good results.

Wirehairs,

I am a fan of J-B Weld (AKA: Epoxy Steel).  From what I see there, I would get two thin steel washers to fit, and a nut-and-bolt to fit through the plastic and the washers.  Sandpaper or scuff the plastic where the washers will be, on each side of the plastic, so there is no glossy finish there.  Epoxy the washers to each side of the hole, inside and outside.  The nut-and-bolt just holds everything together for the night.  The next day, remove the bolt and toss it in the bolt can.  You now have a nice, new hole made of steel.

Some people say that epoxies do not hold on that type of plastic, so try a gluing test, first.  Epoxy something to an out-of sight place inside the fairing (sandpaper or scuff that spot first, of course), and see if J-B Weld is going to do the job.  If you like the results, use that J-B Weld to make the repair with the washers.  About the only thing that I have found which J-B Weld will not hold is a margarine tub, so I think that particular brand of epoxy will do the job for you.  Never mix any epoxy in a wax-paper cup or on any waxed surface.  Wax stops epoxy from setting properly, and it may never set, if there is enough wax present.  I mix epoxy in those (free!) disposable salsa cups that you get in the fast-food places.

Cheers,

Here is what I used to repair my entire fairing which included splicing  an entire left upper section on, that I cut from another fairing.  https://www.amazon.com/3M-AdhesiveGm-Adhesive-08116%252c-Cartridge/dp/B00AZAG0UO/ref=sr_1_15?ie=UTF8&qid=1469501318&sr=8-15&keywords=3m+panel+bonding 

I had the same exact problem you're facing only on mine, the entire upper  section was missing where you only have a small tad broken. You have to sand and remove the paint or the epoxy will only stick to the paint. I used aluminum foil furnace tape and simply made a form, mixed the epoxy and rebuilt it. It's expensive but you get allot in a tube and once you use it you'll understand why all the professional body guys praise it. You have to be extremely careful with it, it sticks to just about anything that's not oily and it will NOT come off with out doing damage. The only thing that sucks is that it requires a special gun to dispense it. You could prolly make something work though, I see all those cracks, On mine I used the epoxy underneath and built those type of areas up to stop that problem as well.
