FWIW, I would note where its currently adjusted (with respect to full out or full in) and run the adjuster out until it begins to slap again then turn it back in 1/2 turn. Check that setting against your original adjustment to see if you were close. Certainly nothing scientific but it may ease your mind. Then again, maybe those were the web instructions.

And for $60 you could go back to Honda and ask for the new and improved version. P/N 14520-MBW-J23 replaces P/N 14520-MBW-J21 which was the original.
