Yeah, I've always done it by eye at the track too.
Up against something stationary .... tree, rock, fence post, car tyre, whatever.

After having wrecked my bike a few times street racing (a sordid past), I learned the quickest, best way to align forks perfectly. The key to it is having two pieces of rod or tube about 2 feet long. That's just an approximate, the longer the better. But 1.5 feet would be the minimum. THEY MUST BE AS STRAIGHT AS YOU CAN GET!!
lay the rods across the forks, one of them as high up the fork tubes as possible, the other one as low as possible. The big deal here is to make sure they are resting on a machined surface like the chrome of the sliders and the machined part of the fat upper (upside down forks) parts. Stand over the bike looking down the fork tubes and looking for the ends of the tubes to line up. If they don't line up, loosen either triple clamp, put the front wheel between your legs and tweek. It usually take two or three shots at it until the tubes/rods line up perfectly.
Once everything is in alignment, tighten the triple clamp and recheck the alignment. Sometimes if the triple clamp gets severly bent it will try to move the forks back out of alignment.
BTW, if the tubes/rods don't want to stay in contact with the forks, like wanting to roll down the fender or whatever, you can attach them to the forks with a couple of rubber bands.
On the WR, I have been able to stuff the upper one behind the number plate just above the headlight. My rods are only about 1/2 inch diameter. The lower ones I usually just put on top of the front tire and secure with rubber bands.
