Hey Jethro: I had tapered bearings installed in my '91 backa few years ago, and it made a tremendous difference. Can't remember the exact brand - but my dealer knew all about them and ordered them direct. I think all told it cost me about $120 installed. If I had to guess I would say they're probably Timkin bearings. I do know that you can also buy "Smooth" tapered bearings through Old Bike Barn for around $60. Good luck. http://www.oldbikebarn.com/part.php?id=3891&subcategory=Steering%20Bearings&bike=VFR750&DisplayPerPage=10
I found them on E-Bay from DESMO_l who seems to carry kits for all makes. It was only $29 plus shipping which isn't too bad. I will let you know how the install goes.
