• Use Honda 4-stroke oil on the specified bolts and nuts. Inaccurate
torque or cross threading may occur if the specified oil is not used.
• Check the crankcase cover bolt seating surfaces before tightening the
cover bolts. If the crankcase cover painting peels off, remove paint
from the bolt seating surfaces, then tighten the bolts.
