best way to tell if forks are bent?

[old man roger]

there is a way to check with out taking them apart , it's not as precise but if they are bent a good amount it is easy to tell just by taking the front wheel and fender off and spinning the bottom of the fork 360 degrees ..

measure the distance between the chrome part of the forks right where they enter the cast part , if they are bent the distance will change as you rotate the fork ..
