Accuracy before coverage
Everyone gets the guided diagnosis — the tests are accurate for your engine type, not just for models we have catalogued. Part numbers are held to a higher bar: if your exact machine is not in the verified catalog yet, HandsOnFix says so and shows you which numbers to go and find, rather than naming one it has not checked.
Tests, not guesses
A diagnosis comes from checks you actually run. Spark, fuel and compression behave the same on every four-stroke, so this works on your machine whether or not it is in our catalog.
Exact model for parts
A part number changes by model, engine code and serial range. We match the full identifier before we will name one.
No unsupported parts
OEM part numbers and purchase links appear only when the fitment has been reviewed against a manufacturer source.
