| "officially" there should be 17 clicks, although no. 1 can be counted??
What you may have is some dirt or such like on the valve seat. The screw is on the end of the metering valve and if something's on the valve seat then you'll lose some clicks. ie you'll never bottom it and so rather than starting from "1", you'll be on "6". Counting out you'll then get an odd number.........
I doubt you've got mismatched forks. |
