I have a 87 zx750R and am thinking about dropping a tooth on the front sprocket, but I don't wanna lose too much in the top end. Anybody have a old 750 with 16f 47r sprockets and has dropped to 15 teeth on front let me know what your results were.

I went to -1/+2 on my P5 7R and it's still good up to 155 or so. I love the acceleration the bike has now. I wouldn't go back to stock gearing for anything.
