Just saw the email address and i've emailed them as well
Hopefully its corrected in the next issue. We dont want people running around fitting K&N's thinking the bike will automatically adapt. The R15 will inevitably run lean with a K&N filter until the AF ratio is corrected manually. This is also probably something you dont want to encourage either because most of the yamaha showrooms either dont have the handheld tuning unit or dont know how to use it
