Hey guys!! I dropped my '87 R yesterday. I tried to pass the car from right side and I was making right turn, the driver of the car suddenly decided turn right on the same corner. She blocked my way. Only thing I could was hit the brakes as hard as I could. Avoiding to contact her car, I dropped my bike on right side and slide. Top cowling's thinest part (little upper of the mirrors) are completely separated, and the right side cowling got some cracks and scraches. Do you guys have any recommendation for plaster, glue, or plastic welding? Or maybe used cowlings for sale? Any opition will be appreciated!!

I am interested to hear if there might be a shop somewhere who could repair the fairing on my CBR. The main right hand side fairing on my bike was cracked last season (long story, but it happened while the faring was off the bike) and though they aren't big, I would love to have these cracks filled (welded?) and painted. Any ideas on a place I could send this panel to for that work? The panel is otherwise fine except for these two roughly 1" long cracks. Would I be better off just selling this panel as-is and putting the $$ toward a new one? Anyone interested? I suppose I have all winter to think about this...

Plastic welding is the best option. It makes for a strong join and provided to person who is welding is good then with a bit of sanding down prior to spraying you'll have a perfect finish, and you will still have your original parts. I spent £75 on having mine done and you would never know the difference unless you were to take the parts off. Good luck with your repairs.

Keep hold of your fairing as they are expensive and it would be easier to make a minor repair than total replacement. As for where you would get them repaired, try a local motorcycle shop (not a dealer) they will be able to advise you. Good luck

If all else fails you can "skin" the fairing with a layer of Carbon Fibre or Kevlar.

Try this link

I've been thinking about buying a plastic welder as well. Looks like they have a good selection for all types of plastics.
Hope this helps

I've done some repairs myself using this:

http://www.plastexexpress.co.uk/

It's great for re-forming tabs and brackets that have snapped off, for cracks, even for rebuilding threaded holes where screws go in. But it wouldn't be any good for large areas of damage.

Thanks for the good advice guys. I figured it would make the most sense to keep the parts I have and have them repaired. Any suggestions on a good shop who could do this work - both the plastic repair and painting? (preferrably in the Northeastern US but I could ship the panel anywhere if the price makes sense) Thanks.

I went with fiberglass in lou of plastic welding. JMO but I think it looks a bit better and is stronger in the end. Its probally a bit harder to do but I think it was worth it. *shrug* Just make it look good in the end ;)

Guys!!
I have been fixing my 87 Cane, and tried to use "bimper repaire kit" that you can easily purchase from any kind of aouto part shop. IT IS WORKING!! It still have flexibility after completly dry. You can sand it and use as filler or adhesive. I don't know how strong it is, but please see some pictures that I applied it to some cracks and a seperated part on the upper cowl.

For above pictures,
Top: You can pick this almost everywhere. I got this from Wal-Mart.
Middle: Left side. There was a crack the length about 5 in. This is after second coat.
Bottom: Top cowling. Actually both side of this part is seperated right side is already hardened.

This bumper repair comes with some mesh. You can use the mesh for reinforcement.

I used the plastic doctor in GA I believe. Did a nice job fixing a few cracks, and prepped for paint. Then they sent the panel off to the painter. I rcvd it ready to put the 1000 decal on and bolt on. Pricey but nice work.
