1979 Honda CB400TII Hawk II Intake Holders & O-Rings

Check whether an intake leak involves a hardened holder or the seal at the cylinder head before ordering. The 1979 Hawk II uses two holders; each replacement comes with an O-ring, while a separate service pack supplies four intake-joint rings.

1979 Honda CB400TII Hawk II · Intake Holders & O-Rings Buying guide

Choose between complete holders and separate joint seals

A holder replacement and a seal-only repair have different package quantities. Inspect the rubber body, head-side joint and fitted clamp before deciding how many complete assemblies or spare rings to buy.

Parts to consider

Count complete holders by intake location

One holder and one O-ring are supplied together. Two holder assemblies service both intake locations on the Hawk II. If the rubber bodies remain usable and only the head-side seals require replacement, compare that narrower repair with the separate O-ring pack before placing the order.

Keep the package count clear

The separate ring package contains four 40 × 2.6 mm O-rings. Two stock holder joints use one ring each, so the package quantity exceeds one pair of joints. Check the existing band clamps separately; a holder-and-ring order does not establish that new clamps are supplied.

Ordering questions

How many holders do I need for both carburetors?

Two holders are used on the 1979 Hawk II. Each featured holder includes one O-ring, so two complete holder assemblies cover both intake connections.

Should I also buy the four-ring pack with two new holders?

Each new holder already includes its O-ring. The separate four-ring pack is useful for a seal-only repair or spare rings; avoid adding it solely because two holders are being replaced.

Which holder reference should I compare?

The holder replaces 16211-413-000, with O-ring references 91325-413-830 and 91325-567-005. Check the fitted carburetor connection and mounting arrangement if the intake has been modified.
