ok the best way to tell if your forks are bent or not (I know this from a very extensive experience...) is to measure the distance between the to axle holds.
Loosen your upper and lower triples, but do not let it so loose for the forks drop off.
keep the fork tubes leve at the top, then twise one leg at a time, 1/4 of a full rotation. Measure the distance between the to fork bottoms. Keep twisting and keep measuring. If your forks are even slightly bent, the distance between the 2 legs will change as you turn.
I found this out when I can only install the front wheel with OEM spacers when my forks are pointed certain way ;D in the other ways there isn't enough space, or there is too much space.
Of course you can always put the fork leg in a vice and use a dial indicator to measure the tube while you turn it. If you have the equipment.
