So, I have just read the second magazine review that says the rear shock must be removed to adjust the rear shock preload. This was in MCN this week, I think previously it was Motorcycle Sport & Leisure that reported this misinformation. This is not correct. While the tool supplied in the tool kit is practically useless, you do not need to remove the shock. All you need is a punch, big screwdriver (I used an 8" 3/8" drive socket extension) or something similar. Get access from the left side cover and push the adjusting nibs the direction you need to go to decrease or increase the spring preload ring. (Righty tighty, lefty loosey). You may need to use a rubber hammer on the extension if you can't push hard enough with your hand only. Now throw away that preload tool and use the space in the bag for a proper mini vise grip.
