Frequently Asked Questions
How many CB400F intake valves are included and required?
One Japanese-made intake valve replacing Honda OEM 14711-377-000 is included. The four-cylinder CB400F uses four intake valves, so four are required to replace every intake valve in one engine.
What should be measured before installing a 14711-377-000 intake valve?
Measure stem diameter and guide clearance and inspect the seat contact, valve spring, retainer and keepers. A new valve alone will not correct a worn guide or an off-center seat.
What final checks are required after intake-valve service?
Verify installed spring height, cam timing, valve-to-piston clearance and valve clearance to Honda specifications. Perform a leak or compression check after assembly and correct any sealing problem before hard use.
