How deep into top triple tree can fork tubes be "cheated" to raise front end?

Installing one of these really diminished that "vague" feeling in sweepers.  Maybe it would help what you're feeling

I actually have one of those - one of the first things I put on when I started experiencing the handling issues thinking maybe I was getting drivetrain flex.

Update - I've really started tearing into this biznatch and am going to try to eliminate all possible points (that I'm aware of) of pivot & movement that could have enough wear to create sketchy handling.

Front motor mounts were replaced as of yesterday. I *think* there is some improvement, but I guess I'm so hyper-sensitive to any little bobble, weave, etc now, I feel like I've somewhat lost the ability to determine what movements are reasonable/normal or not. But, I think it helped some - it certainly can't hurt at this point.

Next, I'm getting the steering head bearings & cups replaced, and if the issues still exists, I'll do the swingarm bushings, bearings, and pivot shaft.

After that, I'm out of ideas.

What tire pressure are you running.  I have a 2011 RGU (same frame) and found the tire pressure to cause what you describe if it is too high.  I like the 40# rear and 39 / 40 front.  If the pressure is a little high and then on a hot day it climbs from road heat and flex it gets absolutely freaky.  When this happened I lowered it a PSI at a time and when I hit that 40# level it was back to normal.  It's a no cost test for you.  You need to know your gauge is correct first.  Carry a 12V pump with you and experiment.  As you hit the levels only a few pounds higher it can make your sphincter twitch at highway speed. You may want to do both tires at the same time.

When I checked pressure a day after tire install, it was about 38 front/40-41 rear - I typically run 36-38 front, and right at about 40-42 rear pretty consistently. I'll pick up a better tire gauge and test this theory as well, but I think I'm still moving forward with the steering head refresh, I feel like it's good to eliminate all possible variables.
