Slowly upgrading my Ripmo. I just took off the NX RD that came on my build and put on an XO RD. I have it working okay but the B-limit screw needs to be all the way screwed in, it could probably use another turn but its maxed. My NX RD B-Limit screw was only about half way in, sat right in the middle... Just seems wrong. Anyone have any insight here?
