Since attaching my windshield it has made high speed riding more comfortable, however anything over 40mph and i hear much more wind noise than without a screen. Is there a way to fix this? I have the screen tilted back at the same angle as the front forks, thanks

Suggest you change the angle or get a different size screen.
The extra noise is because the wind is being deflected onto your helmet. It needs to go either over your head or onto your chest (although that would defeat the object of a screen). Some screens have an extension piece that breaks up the airflow around it.

Just some thoughts.

100% what map said, it's being deflected onto your head, as a test, when said wind hits you, slowly duck down until it goes away.

Different angle or a taller screen is needed.

Well at faster speeds it is a great improvement, but the wind noise is horrible. If i duck my head its not as bad, but if i move my head side to side even slightly i hear wind coming from the sides too

The screen makes an area of low pressure behind it. This sucks air in at high speed which in turn whips around your head, neck and chest.
You need to break the vacuum somehow or deflect the air current.
You can but things to clamp on top to do this but I am not convinced they offer all that they say they do.
The screen on my big bike is electric adjustable. The standard screen I found for my height was shit no matter where is was positioned.
I asked for the longer screen but even this is about 2" too short as I can only find a 'quiet' zone if I lean forwards and hunker down a bit which is useless.
I may look at the clip on things designed for this problem.
The only thing is I don't know if it don't work I can send it back. I will ask that before I buy.

This is what I'm banging on about.

Might sell it then. Its a tough one, did 90mph earlier comfortably except for the noise, whereas without the screen even 60mph is uncomfortable due to wind throwing me about but then i dont go deaf, so i dont know which is better.
It is a cruiser after all though, not like i'll be going fast on it much anyway...

Keep screen, fit it for any longer journeys and wear ear-plugs? if it seems fine other than noise..

90 is too fast really for the 535. The front end is not heavy enough.

Cut a hole in the middle of the screen.
