Surely without knowing the way the dash is suspended or cusioned. Prehaps mounting the dash on more rubber anti-vibration mounts might help??
It is bolted to the fairing/headlight subframe by 3 rubber bolts, hard to describe but should take out the vibes. I think expansion and contraction plays a big part too
the stock screen has the crease at the lower edge, so I'm using the same method as in the thread I posted. that is to heat it in an oven. luckily we have small lab ones at my work so this is easy for me to do. the first attempt was with polycarbonate and that takes more heat to soften. I'm going to try some acrylic next. I bought enough sheet to have several goes so I learn as I go.
Same thing happened to my 899. It was 3 days out of warranty. Took it to duc manc and its been replaced as goodwill, no charge at all, im happy with that!
So here is simple explanation of what is involved. You cut the Perspex/ polycarbonate up to you. Into a rough shape to fit inside the carbon surround. Then heat the cut out screen in a oven until plyable and force it with the surround over the old dash this forces it to take the shape of the dash and fit nicely into the surround... hopefully
My mates RSV4 has gone the same way. Bit daft if it is UV IMO. Ducati don't like rain OR the sun now...
Ok here is the Perspex done. Once the protective film is pull of it looks pretty good Next stage is to cut the cracked old screen and then reassemble.
I will have ago at another polycarbonate screen as that, in theory, should be more scratch resistant. But to be honest I doubt it will be a problem with the perspex as you not really touching it much, just dusting really. plus if I make a couple more before I cut the old screen out, I can pick the best one.
If you can keep the scratches off the inside when u fit it happy days.. Put a screen protector on the outside which should help. Shame we can't knock up a small mould so you can heat up and press a few over a some dedicated tooling. I can get the acrylic/perspex laser cut so it doesn't seem an impossible task
The trickiest part of this is cutting out the old screen. And filing it back to give a smooth edge. I made a few lenses the polycarbonate ones are a no go. It needs to get too hot and cools too quickly.
So here it is. It's not glued but you can see much better it looks. IMHO. I will put a coat of black paint around where the old screen was removed as some of it showed up lighter the the rest so some paint will hide that. I'm leaving the carbon look surround I'll get used to it.
Instead of filing the edge try scraping a steel rule across it, Effectively draw filing it. Works best with the edge of a freshly guillotined piece of stainless. works wonders on plastics You'll get an amazing edge (Apologies if you already know this)
