I also seem to remember 48/52 but that number may be for a naked Standard. You probably should weigh the bike to get a reliable number, which to be accurate should include you, in full regalia.

If you are finding the suspension too hard, a reduction in the amount of fork oil or a change to a lighter oil may help.
This is a complaint often heard after a change in fork springs, but less oil (more air) seems to do the trick.
The issue of imprecise steering may be related to the condition of the various suspension related parts. Shock bushings for instance can have a negative effect if they are worn oval. You might also check for wheel bearing play, both front and rear.
Rarely problems have been reported with worn or improperly torqued swingarm bearings.
Please keep us posted on your progress with this, it's a welcome change from the usual problems we hear about.
