Valve Clearance Setting Kit
The 'adjustment noise' is the result of excessive valve lash in the 4-Mix engine. When the gap between the rocker arm and valve stem exceeds 0.10mm, the components collide rather than glide, producing a rhythmic ticking sound. This kit provides the specific feeler gauge required to recalibrate the mechanical interface to factory specifications.
