Title: Upper Faring Material
Post by: TEDZ on April 11, 2011, 08:19:32 PM
I have a 1984 1100 with a small crack in the upper faring.  Is this ABS?  In the past with other bikes, I've been able to use ABS plumbing cement and a patch on the back side.  If it's not ABS, what is it?
Thanks.

Marine? Going under water in the near future? Maybe just skimming along the top at high speed? There are better fixes for ABS repair than epoxy, like welding with heat and filler material and some other solvent & powder based stuff. It is tough to get the epoxy to properly bond to ABS. Lots of surface area in the area of repair might work for a while. It will like likely separate and you will need to repair again down the road.

I'm not sure about ABS, but I repaired a large plastic trash can that some industrious mice had chewed a 1" hole in the bottom of, with some of that two part green putty, that comes in a tube -because that's what I could put my hands on first.  Like this stuff:

I mixed up a ball a bit bigger than a quarter and flattened it, and stuffed it unceremoniously into the hole.  What I do know is that I can fill it to the top with water and it won't leak a drop.

I was suitably impressed.  I'd bet if you drilled a few strategic holes in the fairing around the repair, and ensured the epoxy was worked into those holes -even maybe mushroomed on the underside with the stuff, while also making the repair itself, there'd be no 'separation' whatsoever.

I tried Marine-Tex once, with so-so results.

As has been posted, plastic welding or a product like Plast-Aid works better.

There are plumbing fittings made of ABS, so I plan to use that type of cement to put a flat ABS patch on the backside.  I just want to keep the crack from growing.  Has success that way in the past patching a trunk lid made of ABS.
One of the little vents that runs along the top side of the faring is also loose, so I'll try using the ABS cement to secure it.
