What are they off of? If the tubes are chrome and they are bent the chorme will look distorted, I have a set off my F4i that are bent and i'm not even sure how it happend never hit anything or crashed real hard. If there inverted you should be able to tell pretty quickly. if you have them mounted on the bike put the axle through the forks without the tire and look at them from the side if the triple is square to the frame and the axle is not square you'll have your answer. just my

If its a possible bend, Ill take the fork apart. and roll each separate tube on a surface plate or something as flat as i can to see any wobbles.

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 ..

+1 might even be able to do it w/o taking it off, just get at eye level

Awesome ideas! Yeah I got the 954 frontend n its been sittin in the garage. I went n slid them into the tripples and went to put front wheel on n axle thru it and it just seemed like they were to far apart at the bottom axle clamp.. Like it was missing a spacer almost, about a 5mm gap or so. I didn't tighten the axel bolt tho, maybe that would pull it tight? The front isn't on the bike yet due to needing seals.
