Just got back from the garage.
Question 1: the bottom of the shock has the numbers 1 through 5 on it. How do you know which setting you've chosen? Is it where the number lines up with the bottom nut that holds the shock onto the bike (in other words, facing the side of the bike)?
Question 2: i'm assuming it was at 1 before, as the manual states. to attempt to resolve my issue, i should try it at 5, right? that would make the bumps softer?
Sorry to be such a dumbass.
