I installed the kouba links last winter and as said earlier, you have to loosen the top clamps AND the bottom clamps on both sides (4 total) to raise or lower the front end. Use a floor jack with a small piece of plywood under the headers to lightly support the front end under the exhaust headers as far forward as you can before you loosen the clamps. I loosened the bottoms on both sides first, then the tops. Then slowly let the jack down which drops the front end (raises the fork tube thru the clamp), until I got the required 1/2 inch on both sides lowered. It did require a little jiggling of the handlebars to get both sides as humanly possible to the same drop of 1/2 inch. Maybe loosening the clamps alot more than I did would let the tubes slide more freely, but I was to chicken to do that, so I just loosened them "enough". Then I tightened up the top clamps, then the bottoms, then removed the jack. Took about an hour total, as I went very slowly. I put the bike on the center stand before I started also as I had no one to hold the bike upright. If you use the sidestand instead, i figured that the tubes would not slide as freely due to a little torqueing of the front fork since the bike is not distributing the weight equally to both arms of the fork. To raise the front end, instead of lowering the jack, you would raise the jack a little, pushing the front higher thru the tubes. I double checked the torques of the clamps about a couple of days/20 miles later to make sure every thing was up to snuff (and there was no change).
It's kind of confusing when using these terms of lowering or raising. Remember the front fork is not going up or down, but the front of the motorcycle is moving up or down on the fork tubes. So more fork tube above the top clamp means the front of the bike is lower and less means the front of the bike is raised.
And you sure don't need to remove the front wheel, fender or anything else. The top clamps are easy to loosen/tighten. The bottoms are a little more difficult, but can easily be reached from the bottom side with the use of a good light to illuminate the area. You can see the bottom clamps from the top, but can't really get at them from there. I used my 1/4 inch drive torque wrench and socket with the hex that fit the clamp bolt. Things are tight down there but I could do it easily even given my advanced age of 60 and short fat stubby fingers.
