I would be looking at them now. You may find them chipping away in the corners. Carbon fiber reeds or stock are good. Carbon fiber reeds are Supposed to give better throttle response and one or two horsepower.
My stock reeds were chipping away in the corners at around 7000 miles. I replaced them with the carbon fiber reeds.
Probably good advice. I'm at 11 500 miles on mine and they still look new, and running strong...but nothing wrong with such tight maintenance schedules either. Being pro active generally always pays off.
