When in the biggest gear, biggest cog, the chain rubs against the cage of of the ospw. I already upsized the chain by 2 links from the 2 links after where they meet method.

The indexing for all the other gears is good, but when I try to shift to the 2nd biggest gear, it always tries to shift to the biggest gear.

B screw feels like its not doing anything, the top of the pulley wheel isn't hitting the buggest cog anyways.

Honestly really stumped, the only thing that I think could be causing this is the ospw really.

Chain too short? My first time working with an OSPW

    Chain rubbing cage means you need to play with the L limit screw. I ran into something like this on mine because the ospw assembly doesn’t seat as flush as the OEM cage (in my case, the cage was too far inboard on the tallest gear (smallest cog) even with the H limit screw backed out all the way – I actually ended up just taking off the ospw and going back to OEM.
