I just got home from a ride and noticed this splatter on the inside of the screen. I'm not sure what it is?? I tried to wipe it off, but noticed it was on there for good. The brake resivor doesn't appear to be leaking. Is it possible this happened from vapor escaping the brake resivor? Anyone else ever had this issue? Thanks

I took some fluid out thinking it may have been overfilled. I'm pissed time for a new screen!

Have you ever noticed roadrace bikes with a wrist sweat band around the masters? This is why.

And yes, you don't want to run your reservoirs full-full. That's why they vent. Leave some room for fluid expansion...midway between lines is fine.
I read that Guy Martin ( IOM TT) fame says that at high speeds the fluid will be sucked out of the brake / clutch reservoir unless a few relief holes are drilled the front bottom of the screen to release the vacuum.
Looks like a classic case of split coolant tank to me...
It has happened to me also and I can't get it off. Looks like I will have to get a new screen too.

I second that...
I third that! Check it out.
On a 1098?
Dunno, do they have a coolant overflow tank in a position likely to spray the screen if it leaks?

But if the screen's spoilt then it probably is brake fluid...
Yes it's a 1098S 2008. It only has 1,350 miles on it. Where does the coolant tanks typically leak from? Does the tank go bad with that few of miles? Also if it was coolant wouldn't it just wipe off the wind screen? I didn't think coolant would etch the screen? Interesting about the high speed comment to because it was the first time I really got on it and this is the first time I've ever seen anything on the inside of the screen. When I took the cap off the reservoir the inside of the cap was completely wet which is making me think it was overfilled.

It's brake fluid sweating out from the reservoir...the speed angle was only to make you feel good. Savvy?!

I'd say definitely brake fluid. Mine did the same thing,
fubar'd my nice new Puig screen.
Just glad it didn't hit the paintwork!

I'm thinking of going with rizoma reservoir. Has anyone had experiences with them splattering or leaking fluid like the picture I posted??? I took some fluid out of the stock reservoir which seems to have fixed the splattering/leaking problem.
I noticed nothing was stated really about the windscreen itself. While the first objective should be to correct the reservoir from erupting again, the screen may still be able to be salvaged if you care about it. There are several products out there, but you could use something like Meguiar's PlastX?

http://www.meguiars.com/en/automotive/products/g12310-plastx-clear-plastic-cleaner-polish/

A quote about their product, "Cutting-edge advancements in Meguiar’s® exclusive Microscopic Diminishing Abrasive™ Technology (MDAT) remove light oxidation, chemical degradation, surface contamination, stains and light surface scratches with ease."

It's $6-$7 and can do nearly everything from polish headlights to removing these stains from your windscreen if you have the time and effort invested into doing so, without having to buy a whole new screen. Heck, it could even polish up your screen to remove any minor scuffs scratches and make it look near new again.

Just a thought, unless you have already committed and bought the new screen for your bike already.

you might be able to polish it out using a fine buffing compound.

Thanks for the tip. I actually gave that a try, but was unsuccessful. I'm a perfectionist and couldn't stand seeing the screen that way so I ended up just buying a new one. I now have sweat bands on the reservoirs though.
