Use a 17mm box-end wrench to hold the slide adjuster and unscrew its locknut with 10mm socket.  Then unscrew the adjuster.

At left, you can see the slider retaining screws inside the top of the slider.  It is extremely important to use a philips-head driver that fits perfectly.  BE CAREFUL, you can see here, the screw on the right is beginning to get wallowed out.  It's a good idea to replace these particular screws if they show any sign of wear.  If you can't get one of them out, it's fairly easy to drill the top of the head off.  I used a 3/16ths titanium bit and the head came right off.  Remember all you want off is the head...so you'll leave enough of the screw's threaded shaft (after removing the adjusting rod and holder) to grab with needle-nose pliers.

Inspect the jet needles.  I bought new ones a couple years ago, so they're in pretty good shape.  Note the two dots on the needle on the left.  That turned out to be dirt.  If they were pitted near the bottom (they're shown  upside-down), it'd be time to replace.

Notice the position of the clip.  By default Honda puts them in the center groove, or third.  With my cam and other tweaks, my bike was explosive at the top end, but running rich at the bottom and midrange.  I don't spend a lot of time running above 5500rpms (one speeding ticket was enough, thanks), and normal riding was producing a lot of carbon...I put the clip in the second groove to lean out, or actually normalize the bottom end and midrange.
