If your motor feels tired, power delivery isn’t what it used to be, or you’ve experienced a major failure, a pro-level engine rebuild could be the answer. Many riders and performance enthusiasts ask the same questions: How long will it take? How much will it cost? What kind of performance gains can I expect? At EPM Motorsports, we’ve rebuilt engines for everything from daily riders to full-on race machines, and the process is far more involved than just swapping parts. Here’s what you can expect when investing in a professional rebuild that restores reliability—and unlocks performance.
A professional rebuild is not just about replacing broken components. It’s a complete teardown, inspection, machining, and precision reassembly that restores an engine to its full potential. Unlike a quick fix, a rebuild ensures every component is measured, tested, and refined to exact tolerances. This level of detail results in reliability that lasts—and a motor that feels alive again.
When you bring your engine in, you’ll want to know how long you’ll be without your machine. The timeline depends on parts availability, machining needs, and the condition of your motor, but here’s a general breakdown:
On average, a rebuild takes 2–4 weeks, though complex projects may run longer. Precision takes time, but the results are worth it.
Cost varies depending on your machine and your goals. A basic rebuild aimed at restoring factory performance typically includes new pistons, bearings, gaskets, and machining. Performance-focused rebuilds add upgrades like high-compression pistons, ported heads, or aftermarket cams, which increase both the labor and the parts bill.
While some see the upfront investment as steep, the value lies in extending the life of your machine and having the opportunity to integrate performance upgrades at the same time. In many cases, rebuilding an engine offers better long-term value than sourcing a replacement.

So, what’s in it for the rider? Beyond simply fixing what’s broken, a rebuild can enhance performance in ways you’ll notice on your first ride:
A well-executed rebuild transforms your engine from tired and sluggish to sharp and responsive, giving you confidence every time you twist the throttle.
Engines don’t usually fail overnight—they show warning signs. If you’re experiencing excessive smoke, knocking noises, oil consumption, or noticeable power loss, these could be indicators of deeper internal issues. Poor compression readings, metal shavings in oil, or repeated mechanical failures are also strong signs that a rebuild may be necessary.
Knowing these symptoms early can prevent catastrophic damage and save you from more costly repairs down the road.
A freshly rebuilt engine isn’t ready to be pushed to the limit on day one. Proper care during break-in is critical to ensure your investment lasts.
Key steps include:
A rebuild gives your motor a new lease on life, but how you treat it afterward will determine how long that life lasts.
Not every engine needs a rebuild, but for riders chasing performance or trying to extend the lifespan of their machine, it’s often the smartest move. A rebuild makes sense if your motor has high mileage, recurring issues, or if you want to add performance upgrades during the process. For cases of extreme damage or if replacement parts are no longer available, sourcing a new engine may be the better option.
