Help thread: error code p0087

For error code p0087, write your exact bike model/year/mileage and when the symptom happens. Otherwise it's roulette.

My go-to for error code p0087: baseline checks first (battery/grounds/air filter/anything touched recently). Boring wins.

Quick question on error code p0087: would you test it right when it happens, or once you're back in the garage? Faults love hiding.

Thomas Spagnoli: workshop approach for error code p0087

I like keywords like 'error code p0087' for search, but the fix comes from method. Here is a practical workflow that works across brands.

1. Nail down what error code p0087 really means on your exact bike: when it happens (cold/hot), RPM range, load, and any recent work.
2. Do the boring baseline for error code p0087: battery + grounds, connectors, fluids, air filter, spark plug, and fault codes if available.
3. One change at a time for error code p0087. Test, write the result down, then pick the next test. Random parts swapping is not diagnosis.
4. If error code p0087 is tuning/derestriction: make the bike healthy first, confirm legality/safety, and avoid unreliable 'quick fixes'.
5. If error code p0087 is fuel/carb: check for air leaks, fuel level/flow, pilot circuit, and correct jetting for your setup.

If you want the full step-by-step method, the Motorcycle Mechanics Course on this platform is free. It’s built around real workshop logic: fuel, spark, air, compression, charging and safe testing.

Post your bike model/year/mileage and the exact symptom for error code p0087, and we can make the next test very specific.

Thanks. I'll post an update for error code p0087 once I run the baseline checks so this thread is useful.
