I went back into the garage and spread those invoices across the bench. Grip had left them folded inside a clear sleeve on the motorcycle. They listed cleaned carburetors, adjusted ignition points, replacement wires, a new condenser, and one expensive service described simply as a "complete performance inspection." Each document was professionally printed. None contained evidence of a sustained road-load test matching the circumstances of the accidents.
At the bottom of the earliest receipt was the name of a Sacramento business: Valley Iron Works. I wrote it in my notebook without knowing it would matter later. Then I marked the dates and compared them with the timeline Grip had given me. The first service had happened shortly before the earliest failure; the others had followed in increasingly frustrated succession.
I was tempted to call him right then. I could have said, "I reproduced it. It's electrical. The other shops missed it." Those words would have made me sound clever and might even have earned a little respect. They also would have been incomplete, and incomplete truths have a way of becoming expensive lies when someone trusts them with their life.
At one forty-seven, I leaned against the bench and stared at the motorcycle. The ignition failure had no clear cause in the usual components. It appeared when heat and vibration joined in a particular way, then disappeared when they stopped. Hector had once told me about a customer's machine that failed every time it struck a certain stretch of washboard road. A mechanic had replaced nearly everything connected to the engine before Hector discovered the real trouble was in a place nobody thought to examine.
"Sometimes the problem isn't in the parts," he'd said. "Sometimes the problem is in the bones."
I looked from the engine to the frame. The red paint was beautiful, almost too beautiful. There were places along the backbone and lower junction where the finish reflected light differently, small distinctions that could have been ordinary restoration work. But the engine, transmission, and wiring depended on the frame in ways an invoice for new spark plugs would never reveal.
I took my flashlight and lowered myself onto the concrete. The floor was warm against my shoulder. Above me, the motorcycle's steel tubes crossed and joined in shapes I had learned to recognize before I could drive. I followed the routing of the wiring and fuel line slowly, not looking for something dramatic, only for something that didn't belong.
Then I touched a slight ridge inside a protected section near the front down tube. It was almost invisible, hidden where a casual inspection would pass over it. The surrounding finish was old; the concealed edge felt different under my fingertips. I shifted the light, looked again, and realized I was staring at a precision-made insert that did not appear in any of the factory diagrams Hector had taught me to read.
My first thought was that somebody had once repaired the frame improperly. My second was that the insert sat exactly where a small movement could affect an already vulnerable run of ignition wiring. I examined the surrounding area and found marks that should not have existed there: deliberate alterations, careful enough to hide beneath paint and grime, positioned where ordinary vibration would create a problem only under certain conditions.
