I have a 2009 yamaha R1 I'm going to have my forks re-sprung and revalved and my rear shock revalved. The bike with it's stock suspension handles alright, But it's like trying to wrestle a hog around the corners. I know that by going with better spring and valving should make an improvement. But does anybody know if there is a good starting point of shimming the rear shock to raise the rear to change the rake and help the bike turn better?
