Black vs White shock bushings
A few pages back, somebody mentioned the white spacer being the solution to getting V2 shocks to not leak. Since I've never ran any (I still use V1 shocks, if you can believe that) I measured my V2 shock bushings on my new B4.1, vs the white ones from the V1 shocks.
The V2 bushings (black) are .140", the V1 bushings (white) are .125".
You can either hunt down the white bushings or sand down the black ones on a piece of sandpaper to length.
Hopefully this will end that whole mess of leaking V2 shocks. File down those bushings, people!
