If you have G/S and the forks are getting worn, and most will be by now, do yourself a favor and get a Billet top triple.
The $120- ? SJBMW one fits with a bit hacking, and makes a big difference on worn forks.
Add their tubular lower brace and full synthetic 7 1/2 wt suspension fluid and the forks will be much better - mine are better than the F 650 Funduro forks.
But sorting them is one of my next projects-----.
