I was originally looking into the YZF750 adjustable swingarm pivot when I came across this .. A good educational tool that I'm sure you's will all appreciate..
Here's a great link to get a good understanding to what you do to the rear end and how this impacts on the bike. I'd been aware that R6 rear shock where prone to squatting and reading this confirms to why that annoying understeer out of the corners when hard on the gas out of corners..

And here's the example I found of what an adjustable swingarm pivot is and a small explanation on it

One of my pals in the race club runs an eccentric swing arm spindle / pivot in his GSXR1000 K7 race bike. It allows him to stay with the latest ZX10`s with their traction control gubbins.

came across the RACH TECH's motorcycle suspension bible which has a wealth of information too..
