Ride height is going to change your center of gravity a few milimeters...
The most significant change will be geometry changes... Bikes come from the factory with very neutral handling and plush suspension... Because they are street bikes...
If you want performance you want to set springs to match rider weight... You will never get this by playing with suspension adjustments... If your tires are worn, it makes little difference if you adjust tire pressure... You need to discard the stock springs, and install the ones needed for your weight... The same way you have to replace those bald tires with some with plenty of rubber...
For performance handling Geometry,
First, adjust your chain slack...
Second, measure and write down your stock rear end geometry... Unloaded rear end ride height from Rear Axle to a point directly above the Axle...
Third, you need to lengthen the rear shock with shims until you get a 12.5 degree angle on the swing arm from "Rear Axle to Swing Arm Pivot" this measurement is done with the bike on level ground...... both tires touching the ground...... And both front and rear suspension completely extended / unloaded...
Fourth, Measure and write down your new Rear end ride height...
Now your front end...
First, measure and write down your stock unloaded front end geometry...
Second, adjust your unloaded front end, so it is 50% (Aggressive, Light steering) to 75% (Mild, easy steering) of your rear end ride height... This is done by adjusting the forks on the triples...
Measure and write down your new front end ride height...
From this point you adjust your Sag at 25mm to 30mm rear, and 35mm to 40mm front...
That is what I been told...
