Manufacturer reference: NK600.84 - Cylinder head valve set 22/25 by NARAKU. Designed as a replacement set for the Naraku Racing 4-valve cylinder head (ref. 09300218 / NK600.77), this kit allows for the replacement of the moving parts of the cylinder head on 125cc engines equipped with the YI-3 block.

• Kit contents:
• 2 intake valves – Ø 25 mm

This valve set is aimed at motorcyclists who maintain or rebuild a Naraku Racing 4-valve cylinder head. It is particularly suitable for Yamaha scooters and small capacity bikes (X‑Max, YZF‑R, WR 125) as well as other 125 models equipped with the YI‑3 engine. Please check the reference of your cylinder head (NK600.77 / 09300218) before ordering to ensure compatibility.

Fitting valves requires precise adjustment of the clearance and checking the condition of the seats and tappets: we recommend installation by a qualified mechanic or an experienced DIYer with the appropriate tools (press, spring compressor, shims). This kit provides only the valves; gaskets, springs, or other cylinder head parts are not included.
