Winshield Search

Since I bought my new 1997 RS I have problem with the small piece of Lexan they call Winshield. I'm 5'10" and it seems to be more a deflector (IT cachs all the wind and send it too my chestt and face).

There is no brand, and I'm quite sure is not an Yamaha OEM, since the brackest are more like the National Cycle stile than the originals. Yesterday searching for any mark or logo on the Lexan, I found a code NC136 (A confirmation of National Cycle may be?) but nothing else.

Some one else has the same kind of winshield on the Royal Star. This is about 11" on top of the notch for the headlight..

I would like to know where and what to order for replacement before to buy a full new tall Yamaha one.

Thanks
