11060-3703 Reed Valve Gasket for Kawasaki JS 300 1986-1987

Reed Valve Gasket for Kawasaki SX 300

This reed valve gasket (OEM cross-reference 11060-3703) seals the reed valve assembly on Kawasaki SX 300 watercraft, preventing air leaks that disrupt fuel mixture and engine performance.

Overview

This reed valve gasket is a direct-fit sealing component made for the Kawasaki SX 300, replacing worn gaskets that allow air to leak past the reed cage. The 11060-3703 gasket restores a tight seal between the reed valve and crankcase, helping the engine draw fuel mixture correctly. It is a practical part for riders performing intake or top-end maintenance on the SX 300.

Specs At A Glance

Good To Know

Q: Should I replace this gasket every time I open the reed valve? A: Yes, a compressed used gasket rarely seals reliably again, so fitting a fresh one during reed service avoids a repeat teardown.

Q: What happens if the gasket leaks? A: A leaking reed gasket draws unmetered air into the intake, which can cause lean running, poor idle, and hard starting on the SX 300.

Slight variation in finish or dimensions may occur between production runs, and fit can depend on serial number, so confirm compatibility before ordering.
