She opened her eyes and looked at the timing cover. You've been trying to tell them, she murmured to the engine so quietly it was barely a breath. Haven't you? And nobody would listen. She got the timing cover off in under a minute.
She'd done it 10,000 times in her life on engines far worse than this in conditions far worse than a quiet garage. And when she got it off and looked inside, she stopped breathing for a second because there it was.
The timing chain had stretched. Years of hard miles had worn it just past its limit, and the tensioner that was supposed to keep it tight had worn down alongside it. And the two of them together meant the engine's timing was slipping just a hair, just a fraction, but enough. Enough to rob the bike of its power under load. Enough to make it choke and sag exactly when Cole needed it most. And worse, far worse, she could see the faint bright scoring on the guide where the loose chain had been slapping metal for months.
Another few thousand miles and it would have jumped time completely. And if a timing chain jumps on a big ride at highway speed with a man on it who's ridden a quarter century without a scratch. Emily's jaw tightened. That wasn't a repair anymore. That was a rescue.
Okay, she whispered. Okay, let's get you fixed.
She worked fast, but not rushed. There's a difference, and only people who've done real work under real pressure know it. Rushing gets people killed. Fast is just knowing exactly what you're doing and wasting no motion doing it. She had the replacement chain and tensioner she needed because she'd ordered them herself 2 days ago quietly on a hunch listed on the invoice as miscellaneous engine hardware and stored them in bin 22 where nobody ever looked.
She'd known some part of her had known from the first morning and she'd made sure the parts were there waiting just in case the day ever came when she couldn't stand to stay quiet anymore. That day was now.
Her hands moved with a precision that would have stopped every man in that garage cold if they'd been there to see it. This wasn't the work of a hobbyist or a parts clerk who'd picked up a few things. This was the work of someone who had rebuilt engines with mortar shells landing close enough to shake the tools off the bench. This was muscle memory carved so deep it had become instinct.
She set the new chain. She fitted the new tensioner. She checked the timing marks three times because you always check three times because the one time you don't is the time it costs a life. Through the window, the men were still in the lot. She had maybe 5 minutes now. She sealed the timing cover back down, torqued every bolt to spec by feel, and wiped every trace of her fingerprints off the engine with a rag from her back pocket.
She gathered the old chain and the worn tensioner and slipped them into her flannel. She left no sign, no note, no claim. As far as the world would know, the Harley had simply mysteriously gotten better. That was how she wanted it. She didn't want the credit.
