Time needed: About an hour.
Now, it's time to install the new forks. Cat knew that after the forks are installed, there should be 11mm of fork sticking up past the triple clamp (this may differ for your bike -- check your service manual). So, before we started, she set her vernier calipers to 11mm. We'll use those after the fork is installed, but it's easiest to set the calipers before you have your arms full of fork. Take your lefthand fork (that's the one without the extra holes for the brake caliper), and start from underneath the bike. Slide the fork up into the fork hole on the lower fork bridge. Keep pushing it up through the fork hole in the triple clamp. Here's where you use the vernier calipers -- measure the amount of fork above the triple clamp. Pull more of the fork up if you need more, or push the fork back down if there's too much sticking up. Test the measurement all the way around the circumference of the fork to make sure that it's even. When you're satisfied that the fork is installed correctly, tighten the bolts on the lower fork bridge and triple clamp.
Repeat the process with the right fork. When Cat did the right fork, she found it to be difficult to push the fork back down to the correct 11mm adjustment -- a whack with a rubber mallet did the job. ;)
The next item of business is to put the front wheel back on. Clean off your axle with WD-40 or some other solvent, and then grease it back up. Cat uses Valvoline's multi-purpose grease, which has the added benefit of being bright pink.
Insert the axle spacer if you've got one (the Kawasaki does; my Nighthawk didn't, for example) and line up your axle. Align the wheel so that the speedometer cable housing is facing the correct way (in the pictures below, the first speedo pic is incorrect, and the second correct).
Now it's just a matter of sliding the axle through the tire. Use your rubber mallet for help if needed. Screw on the axle nut on the other side, and you're all set. For your amusement, I've included the picture of the result of our using too much grease on the axle. ;)
Next up, we're going to reattach the clipons. This is just a matter of reversing the process of removing them -- Cat's clip-ons fit on over the forks, and are then held in place by bolts. Don't forget to check the sides of your clip-ons, too, to make sure that you've tightened all of the bolts.
Now all that's left is to re-attach the brake calipers to the rotor and torque down all of your bolts. To re-mount the caliper, just slide the rotor back between the brake pads (see why you made sure not to squeeze the pads together while the calipers were off the rotor?) and replace the two bolts that hold it to the fork. Use your service manual to tighten all of the bolts to their specified torques, and you're all done! Because Cat's bike is a race bike, she also safety wired all of the bolts after torqueing them, a step that's obviously not necessary on a street bike.
