lower triple tree bent? ST1100

Just a thought...

You did pull the sliders off the fork tubes to check straightness, correct?

You really need to fully disassemble the fork tubes/sliders to properly check for problems. Also fully assemble forks, sliders, and axle into triple tree without springs and make sure the travel is free over the full range. If there is any noticeable drag at any point in the travel, it is likely the fork tube(s) is/are bent.

Did you try alternately rotating the left and right tubes 180? and see if the axle alignment changes. It should if the fork tube(s) is/are bent.

My 2?...

Last statement a good thought..........cept for the fact that lower leg tubes and sliders(hyd.rams) are seperate and have no effect on each other

Actually not true. The fork tubes are connected by the triple trees. If one or other fork tube is bent of you rotate the bent one to various other orientations (while in the triple tree) the relationship of the slider one the bent fork fine will change relative to the other slider. It may move forward, outward, inward, or rearward depending on the orientation of the bend in the tube. Of the bend is at the lower tree clamps the effect is maximize. Of right at the top of the extended slider it may not be as noticeable.
