Moto-House MX Pro Tip:

Because 4-stroke crank bearings do not include seals in this kit, always inspect your existing oil seals during the teardown. If there is any sign of hardening or wear, replace them immediately to prevent oil pressure loss or contamination. Cleanliness is critical—ensure the crankcases are completely free of debris before pressing in these new precision bearings.
