If were talking about the early V11 with the clip-ons mounted below the top clamp, the forks are factory mounted with the top of the fork stanchion level with the top of the triple clamp and the cap standing proud. In this case, I suggest we measure any change from the top of the triple clamp to the top of the fork stanchion, not including the cap.
Beginning with the 2002 LongFrames, the clip-ons are mounted above the triple clamp and, therefor, the forks are already raised above the triple clamp to clamp on the clip-ons. Whatever that actual dimension is should be the baseline to subtract from any alteration to get the actual change. Again, I suggest not including the cap.
Can anyone confirm the amount of fork already above the triple clamp on a LongFrame V11?
