 Thanks for the feedback and the tech info. It seems to confirm my thoughts about the gearing,there is room for some improvement,the Speedo and better mpg are  good benefits too! Going away September to the Italian and Austrian Alps so feel the standard gearing may be more sensible but the torque going uphill is amazing in any gear above 2000rpm! First have to take care of my charging iss ues that have come to the surface on this current trip,looks like the generator and flywheel have failed. Bike has only done 20k since 2007!

Well after reading all the comments, I am going to stick with the 16T front sprocket and notch down to a 42T on the rear instead.  I want to retain lower end power but take the edge of the high rpms at cruising.  According the calculations, I am right in between...... equivalent of a 16.5 tooth front sprocket if you will.... I'll install likely near the end of September and report.
What I ordered is a JTR-302.42 (1992-95 CBR900 fitment is same).

That may be the sensible option if your in the Honda had the gearing optimised at 16 x 43 camp. Sometimes less is more. Would be interested to hear what correction it makes to the speedo and at what RPM's 50 and 70 MPH is reached.

Art, what I did was use the website referred to below, it shows the stock gearing and speeds.  I was more interested in 3500 and up rpm ranges, mainly what speed I was doing at 5000 where my buzz occurs... 100 kph plus usually 20 won't get me bad paper.  I know there is buzz above that, but it starts just at/under 5000..  Everyone's input has been helpful, thanks all.
Plugged in the 17/43 combo in "Custom", then in the next box below, enter 3500 or 4000 rpm in the left box and press the Custom button, displays the various speeds.  Did the same for 16/42 and thought that would take away most of my buzz concerns.  Not that it's bad, just would rather stay south of it a tad, and not affect performance as much as 17/43 would.  So, we'll give it a go, I found JT sprockets in the UK cheaper to my door than ordering here.  They are on the way.
