As we know there are several mistakes or gaps in the Karate Kid. One of those is the whole "Miyagi Turbo" comment Daniel makes to Ali's friend Susan when she asks what kind of bike he has.
The gap comes in when you consider Daniel up to that point didn't know Mr. Miyagi's name, he doesn't learn his name until the following bike repair/bonsai scene.
The book clears up this gap (while creating another however, more on that later.)
Chapter 2, page 9
Beyond the shelf, Daniel could hear a snapping sound. He followed his ears and was startled to find himself looking at an old Oriental man. Daniel stepped back and took in the scene. The man must have been seventy years old. He was wearing blue coveralls and was brandishing a pair of chopsticks. The man - whose name was Miyagi according to his name patch - appeared to be trying to catch a fly with the chopsticks.
Snap!
Daniel found his voice.
"Are you the maintenance man?"
"Hai."
However the funny thing is is that in the book the "Miyagi Turbo" scene doesn't exist. So the gap created in the movie that is answered in the book doesn't exist in the book to begin with.
