I know they are plastic, but what kind of plastic?

What is the best way to fix a big crack or a broken piece?

Normally they are made of a plastic called ABS and the best way to fix them is plastic welding which i'm sure there are plenty of members that can do same.

i think they made of pvc[edit]or was it abs?[/edit], or a very similar form of plastic.

best way to fix a crack is use plastex & a dremel.
take the fairings off, sand down to the plastic for a few mm aside from the crack. Grind a minor channel along the crack only a mm or two deep, sticky tape the fairing into place, and sticky tape the reverse side of the crack to seal it. then plastex it up, and do the same for the reverse side of the crack.

give it about 12 hours cure time (it cures to be reasonably solid in 15 mins, but takes a while to fully cure). then if you cbf you bog up the crack and sand it and spray/sticker it.

you couldtry the heat welding method using a donor plastic like another fairing or something else, but that doesn't quite cut it like plastex i've found. As it takes a while to practice enough to get sufficient heat penetration to make a solid join.

sugar and spice and all things nice??

That'd be the green ones . I've heard black ones contain snips and snails and puppy dogs tails

Hope that helps RG

Hmmm I was going to go and Lick my Fairings then but mine are Black!
what happens if they were Green but they get painted Black?

PVC 40, belive it or not its the same grade they use to make the black drainage piping for ur garden systems.

wear your pants higher !!

Thanks for the replies guys.

This is the reason why I asked...



I got the bike like that 2 yrs ago but never bother to do anything about it.
Apparently the crack got wider after 2 years...
I'm going to sand it down, fix the crack and repaint the whole bike.

Plastic welders always have a heap of past jobs peices lying around and it really pays to match with a fairing off a same/similar bike as they are all apparently a bit different (or so I was told by the welder), he described it a bit like different alloys of metal.
That is they are all "metal" but you use stainless to weld stainless etc.
he only uses "new" kwak to repair new kwak's. That looks like a ZZR so there should be heaps of plastic bits for it lying around.

as far as i know repsol are the major manufacturers for the plastic material that go into motorcycle fairing.

maybe their website could help

Did you have to say that Nannapants........Neka's been outside all morning licking the GayBlade**






**Nb.....spose its a nice change from him trying to dry hump it

I would be seeing a plastic welder considering where the crack is and wanting respray the whole bike. You wouldn't want that crack to appear after the bike has been resprayed
