The pivot insert is behind the nut. You can see it from outside the bike right now. There is a little dowel pin that locate it in place. The reason you have to pull the swing arm is because the RH pivot is held in place by a massive nut on the inside of the frame. You'll need a very big adjustable wrench to get it off.
Okay, I was just seeing that on a frame diagram. It looks like I have to 180 rotate these collars. Yes, that is one big-A nut... I'll get a better idea this afternoon, get some shims, and see if I like the new set-up. Some support a flatter swingarm, but I was seeing you didn't prefer it in another post. Thank you for the help.
Personally, I've yet to reach the mechanical limits of the stock settings when concerning traction. That most likely has nothing to do with the swingarm angle, but rather my level of skill (slow Advanced pace). I would say I prefer a more "loose" rear than most based on my R1 experience, so for me adding mechanical grip wouldn't be the first step in how I setup the bike.
