ULTRA・SE Valve Set Cylinder Head Repair Parts APE

[KITACO 302-1122700 ULTRA-SE Valve Set Cylinder Head Repair Parts APE KITACO 302-1122700]
Designed exclusively for Kitaco ULTRA-SE heads.
Valve diameters (face) are enlarged to φ28 for intake and φ23 for exhaust.
By reducing the stem diameter to φ4.0, the weight is reduced, improving high-speed followability while simultaneously reducing intake/exhaust resistance in the port area, contributing to higher output and RPMs.
Furthermore, soft nitriding surface treatment is applied for surface hardening and improved initial break-in.
Valve clearance: IN 0.05 / EX 0.07
Stem diameter: φ4.0
Valve diameter: IN φ28 / EX φ23
Exhaust valve weight: 20.0g
