One thing I neglected to mention is that you should first very lightly tack glue the joint - perhaps in this case at either end and with it in alignment - with what is known as "medium" CA which is a thicker variant of the thin stuff. In this way, the joint will be stabilized and can withstand the packing of the strand. Avoid filling the joint entirely with just glue alone - it is the glue/fiber matrix working together that provides the strength.

Yes.

Just a side story: I was fixing up and F4 750 EV 03 and I needed a front nose. I found a perfect nose for a great price. The guy shipped it to me in a nice box full of packing material but no windscreen or support for the area where the windscreen goes.

The fairing showed up with that little bridge cracked. The guy was an upstanding gent and refunded my money and told me to keep the fairing. If I ever repair it and sell it, I will give him his money back. Right now it sits in my garage as a reminder.

Hello

I have a guy that can fix that! He did two front fairings for me. He did a OUTSTANDING job! At the moment he is doing a rear tail for me as well. Let me know if I can help out.

I removed the windscreen which was a mistake looking back at it. It fell from around 1 foot height straight on the nose and cracked. So keep that in mind when you are changing the windscreen. Is your guy located in the UK?

In the interest of knowledge sharing, do you know what he did to fix them?

He lives near Jacksonville North Carolina. But I don't know how he does but I definitely recommend him. I will have to put up pictures when I come back from vacation.

I've done a similar repair in the past. If that's ABS plastic you could easily repair that by using a soldering iron on the underside of the crack to weld it back together (use tape on the outer side to hold it in place while performing the weld). Then use filler material (a light application of bondo) to get the girth back. Sand, spray (color + clear), then compound.

The type of plastic is key to the repair. In any case of plastic welding you will need filler material. If that material is not compatible with the plastic of the fairing, it will not hold.

There have been many discussions in this forum about the material used for fairings. The manuals say Thermoplastic Material and that is any plastic that can melt and flow.

I believe that our fairings are polypropylene, but that is difficult to pin down.

In my experience with body materials on vehicles, I do not think MV fairings are polypropylene... not based on what I know. ABS maybe. Polypropylene is very soft and flexible and does not crack easily...or accept paint coatings easily.

I used to be fast....now I just dream about it.
