A disc question (windshield, windscreen, spoiler) with pictures !

Hello. motorcycle: zx9r from 2002 when I drive with my moto, then I have the feeling, my windshield pops the wind directly against my helmet. when I stretch out, I get out of the wind current and it gets more pleasant when I lay down, of course, but that’s not so relaxed. below is a picture, so I am quite normal on the moto and just like that most wind shoots against the helmet and it’s loud. I think the windshield that is watching is a touring windshield, manufacturer unknown. was it already when I bought the moto. shouldn’t a touring disc offer comfort or something? I always hear only racing disk here racing disk there. and now to the actual question, since I started this year (26 years) with motorcycling and here are surely some old hases, which have experiences: benefits me among the current circumstances the conversion to the much said MRA RACING SCHEY ? then I have the wind rather on the chest than on f the helmet ? is it even more pleasant ? if it is important : I lie only in exception cases on the tank, if I mean, that should be now but or if I really drive over 220, which is rare. am about 180cm big on the pictures below you can see how I normally sit on the zx9r. please for experience values. should I just cut the “last” arch of the current? (is then actually the shape of the racing discs…) hm, look forward to input from your side a us. thank you so much, mitfg standards
