A valve clearance adjustment costs hundreds. Skipping it — until a valve burns or a cylinder head needs rebuilding — costs thousands. The math is simple. We adjust to factory spec. No "close enough."
Your engine's valves open and close thousands of times a minute. They let fuel and air in, and exhaust out. The gap between the valve and the rocker arm or camshaft — the clearance — has to be exact. Too tight, and the valve doesn't close fully. Too loose, and it hammers itself and makes noise.
Over time, normal wear changes that gap. The clearances drift out of spec. Slowly. Quietly. You might notice a ticking sound. Maybe the bike doesn't start as easily. Maybe it's down on power. Or maybe you notice nothing at all — until a valve burns and suddenly you're into a four-figure repair.

Not sure if your bike is due? Bring it in. We'll check the service interval for your make and model, listen to the engine, and tell you honestly if it's time. No scare tactics. Just facts.
Book Valve AdjustmentTicking from the top end is the most common sign of loose valve clearance.
Tight valves don't seal. You lose compression, power, and fuel economy.
Tight valves burn. A burnt valve means the head comes off. That's expensive.
We measure and adjust to manufacturer specs. Not "close enough" — exact.
Riders skip valve adjustments all the time. The engine still runs — until it doesn't. Here's how that decision plays out.
$500–$800
Most Japanese inline-fours, twins, singles
Exotics like Aprilia, Ducati, or bikes with complex bodywork can run higher — call for a quote on your model.
$1,500–$3,000+
Cylinder head rebuild, burnt valve replacement
Cost depends on the damage. Once a valve burns, the head has to come off — and that's never cheap.
These are real-world ranges. Most common bikes fall into the $500–$800 range. Exotics with complex valve trains and tight bodywork run higher. Call or text for a quote on your specific bike — no obligation.
It's measuring and setting the gap between the valve and the rocker arm or camshaft. That gap has to be within a specific range set by the manufacturer. Too tight or too loose, and your engine loses performance — or worse, damages itself.
You can — until you can't. Valves that are slightly out of spec won't destroy your engine immediately. But tight valves run hot and eventually burn. Loose valves hammer the valvetrain. Both failures are far more expensive than the adjustment. Skipping it is a gamble, and the house always wins.
Ticking or tapping from the top of the engine. Hard starting, especially when cold. Loss of power. Rough idle. Poor fuel economy. Sometimes there are no obvious signs — which is why the service interval exists. By the time you hear it, it's already out of spec.
Most Japanese inline-fours, twins, and singles fall into the $500–$800 range. Exotics like Aprilia, Ducati, or bikes with complex bodywork can run higher due to the extra labor involved. Call or text with your model for an exact quote — no obligation.
Burnt valve repair typically runs $1,500 to $3,000 or more, depending on the bike and the extent of the damage. That includes removing the cylinder head, replacing valves, machining or replacing the head, and reassembly. The valve adjustment that would have prevented it is a fraction of that.
It varies by make and model. Most Japanese bikes call for it every 20,000 to 40,000 km. Some European bikes have shorter intervals. Bring your bike in or call us with your model — we'll look up the interval and tell you if you're due.
Whether you're hearing a noise, noticing a power loss, or just following the service schedule — bring it in. We'll measure, adjust, and send you out with an engine that's running the way it should. Call or text for a quote on your specific bike.
