A valve clearance service measures the gap between the camshaft and each valve, then brings every gap back into the factory tolerance. Most manufacturers specify a check every 12,000 to 24,000 km, and high-revving bikes like the R6, ZX-10R and S1000RR often want it sooner. Skipping it is what turns a routine adjustment into a burnt valve and a full top-end overhaul, so it is one of the cheapest pieces of insurance on a motorcycle.
| Engine type | What it covers | Price |
|---|---|---|
| Single cylinder — Class 2B | 2 to 4 valves. Scooters and small commuters. | WhatsApp for price |
| Single cylinder — Class 2A / 2 | 4 valves, more fairing removal. | WhatsApp for price |
| Parallel twin | 8 valves, both cylinders measured and adjusted. | WhatsApp for price |
| Inline four | 16 valves. Supersport and litre bikes. | WhatsApp for price |
| VC package with oil service | Valve clearance plus engine oil, filter and full safety check. | WhatsApp for price |
| Shims (if required) | Charged at cost, only for the valves that actually need changing. | WhatsApp for price |
We quote rather than publish a price list, because the real figure depends on your model, how much bodywork has to come off to reach the cam cover, and how many shims need changing. WhatsApp us your exact model and we will quote it properly.
Shim-type and screw-type, singles through inline fours. Desmodromic Ducati valve service is measured differently — send us the model and we will confirm before you come down.
Most manufacturers recommend a check every 12,000 to 24,000 km, depending on the model. High-performance bikes like the R6, ZX-10R and S1000RR may need it more often. Ticking sounds or a drop in power mean it is overdue regardless of mileage.
Most bikes are a same-day job. Inline fours and heavily faired bikes take longer because of the bodywork that has to come off, so we may keep it overnight.
Clearances tighten as valve seats wear. Too tight and the valve never fully closes, which burns the valve and the seat. That turns a routine adjustment into a top-end overhaul costing several times more.
Yes. You get the before-and-after readings for every valve against your model's factory spec. If your clearances are already in tolerance we will tell you and charge only for the inspection.
On simpler bikes, often yes — but the engine has to be fully cold before we can measure accurately, so book a slot rather than riding in and waiting.
No. We only replace the shims on valves that are actually out of spec, and shims are charged at cost.
Send us your model and mileage on WhatsApp. If a valve clearance is due we will book you a slot; if it is not, we will say so.
