fairing repairs

was getting ready to remove the upper fairing to change the low beam bulb again. i find it odd that my low beam has gone out twice and the high beam not at all considering the high beam is used a lot more than the low..... but that's another thread i guess....

i know the picture is a little tough to see but there appears to be a very fine crack running away from the mounting hole.



i'm looking for any advice on how to prevent any further spread of said crack. if it were sheet metal i would drill a small hole at the end to prevent further propagation then weld it up and blend it out but it's plastic and i'd prefer not to drill a hole that i couldn't fill in some inconspicuous way.

so my idea is to chemically weld the crack from the inside but what to use....... super glue? acrylic cement? PCV cement? ABS cement? something else?

has anyone had success doing repairs like this and how did you do it??

Were I in your shoes I would use an epoxy specifically formulated for plastics. I've used it for other plasticky things and it works great.

Were you in my shoes, you would use an unsightly electrical tape repair, but mine's black, not yellow.........

lol. Good answer. I'd use gorilla duct tape, but....

Yeah, some kind of plastic specific epoxy. I wouldn't sweat it too much though. Throw some epoxy on and ride.

I've got some electrical tape around the rear top fairing bolt hole where I cracked it being heavy-handed removing the tank without the fairings: just got pissed and kind of ripped the tank out past the plastics.

That electrical tape has been on there for 5 years. It's hardened into a kind of plastic on its own. I consider it a permanent repair.

Q Bond

a4twenty,
There is a plastic repair product that I have seen on another forum, called Q Bond. Goggle "Broken tab solution, Q bond", you might can possibly see a video or 2.
A friend has used it. Radiator shroud tabs on a Gen1 KLR. Worked great/strong.
Available at Amazon.com and some auto parts stores.

I have used acetone. Brush it into the crack on the back side and give it time to set up. It takes a bit of experimenting. Also plumbers ABS cement with fiberglas drywall tape has worked wonders . I have punched holes in the fairing and managed to glue eveything back in place (I even found all the broken pieces) and it has held ust fine for 4 years. Dont ask how I mange to punch holes in the fairing. I have used this method to reinforce the mounting lugs when they have cracked as well
Hope this helps
Randy

I agree! Since it's just a small crack (hairline even) I don't think that any radical repair method is required. Epoxying a small washer to the bottom side of the fairing should keep the crack from spreading and strengthen the area. Then you don't need to have to worry about touching up the paint either, win/win!
