You can also lower the stock height on the rear shock by almost an inch. I can't find a good link to a walk-through on this--guess I may need to write one for www.wrrdualsport.com , eh?
If you're confident mechanically, basically you unbolt the clevis on the bottom of the shock. You thread the large nut UP to the bottom of the black rubber clicker. Chase the clevis up to the nut, align so you can reinsert the bolt, and tighten the bolt down onto the clevis. Make sense?
edit:: Bike on center lift, and use a jack under the back wheel to help with putting back together.
