After swapping the spring. bolt up the shock . set the pre load with your weight on the bike ,then look at the adgusting ring where it is nearest the overflow tank. this will tell you were you need to grind the ring. I moved the overflow tank slightly . this will be obvious wheen you offer it up.Do this with the shock removed as its fiddly. Set rebound knob to max , and then experiment with the compression adgust screw. pm me if you want more, I've still not got round to trying the r6 shock on my 600 yet .
