Ok, let's review...
Check your tire pressure again, something like 18/26 should be a good start. Set you're rear shocks softer, not harder. One notch down from the middle would be a good spot to start. Loosen the front axle, axle pinch bolt, and lower triple pinch bolts, bouncy-bouncy-bouncy, tighten the triple, tighten the axle. Make sure your rear wheel is properly aligned. Make sure you don't have excessive play in the steering head bearnings (you probably don't or you'd notice it sooner).
It should only take you about 20 minutes to go through all of that. Take it for a spin and see how it does. If you want to make adjustments after that try one thing at a time.
