Thirty-one years of experience.
Four patents.
She had spent her career designing and testing motorcycle engines.
She watched Owen carefully.
Something about his hands had caught her attention.
The way he held the wrench.
The angle of his wrist.
The way he listened before moving.
Eleanor had seen thousands of mechanics.
She had never seen anything quite like this.
She stepped closer.
Two Teeth
Owen removed the cam cover.
He did it quickly.
No wasted motion.
Underneath, the timing chain became visible.
He shined his flashlight toward the cam sprocket.
Then he stopped.
“Two teeth.”
Garrett frowned.
“What?”
“The chain slipped two teeth.”
The timing chain was slightly out of position.
Not enough to be obvious.
But enough to prevent the valves from opening and closing at the correct time.
Owen loosened the cam sprocket.
He repositioned the chain.
Two clicks.
Then tightened everything again.
The entire repair took seconds.
Dale Prescott stared from the crowd.
He had spent thirty minutes with expensive equipment.
He had missed it.
Because electronic diagnostic equipment could not identify a mechanical timing problem on a 1972 Shovelhead the way modern systems could.
Owen didn't need a scanner.
He had heard it.
Garrett crossed his arms.
“Lucky guess.”
Owen moved on.
Garrett's voice rose.
“You hear that? The kid got lucky!”
The crowd laughed.
But Eleanor Graves didn't.
She watched Owen's hands.
There was no luck in them.
Only knowledge.
The Grain of Rice
Owen moved to the carburetor.
He removed the bowl.
Inside was the float.
It should have moved freely.
It didn't.
Owen pressed it at an angle.
Something tiny shifted.
He pulled out a microscopic piece of old gasket material.
Smaller than a grain of rice.
“This was stuck between the float and the bowl.”
Nolan Briggs stepped forward.
“I checked that float twice.”
“You checked it assembled.”
Owen held the debris between his fingers.
“This only catches at an angle.”
He paused.
“Known issue on early Keihin units.”
Nolan's face changed.
Owen continued.
“Harley technical bulletin HD-78-041.”
The crowd murmured.
Eleanor Graves froze.
She remembered that bulletin.
She had worked on it decades earlier.
She looked at Owen.
“How do you know that number?”
Owen shrugged.
“I read a lot.”
Eleanor smiled faintly.
It wasn't just that he knew.
It was that he remembered.
Garrett stepped closer.
“Two lucky finds.”
Owen didn't respond.
He moved toward the third problem.
The Invisible Fault
The third problem was hidden.
Owen slid underneath Black Fury.
His back hit the hot asphalt.
His flashlight moved along the frame.
He found the ground strap.
The bolt was tight.
The wire looked fine.
To almost anyone, everything appeared normal.
But Owen scratched the contact surface with his fingernail.
Green oxidation.
Corrosion.
Road salt and moisture had built resistance between the grounding strap and the frame.
Enough resistance to weaken the ignition spark.
Enough to kill the engine.
Owen pulled a small piece of emery cloth from his pocket.
His father had taught him to carry one.
Thomas had carried the same kind of strip for twenty-three years.
Owen cleaned the connection.
Green disappeared.
Brown disappeared.
Bright copper appeared.
