Kawasaki STX 160 Jet Ski Exhaust Valve Kit

Exhaust valves operate under extreme heat every time your engine runs. Over time, that constant exposure can lead to wear that affects compression, performance, and reliability. This exhaust valve kit fits 2020-2026 Kawasaki STX 160 Jet Ski models and provides replacement exhaust valves for cylinder head repairs or complete top-end rebuilds.

Whether you’re rebuilding after high operating hours or replacing damaged components, installing new exhaust valves helps restore proper valve sealing before the engine goes back into service.

What This Kit Includes

• Exhaust Valves

When Should You Replace Exhaust Valves?

Inspect the exhaust valves whenever the cylinder head is disassembled. If heat, wear, or damage prevents proper sealing, replace them before reassembly.

• Burnt or eroded valve faces.
• Bent valves caused by engine damage.
• Valve stems that exceed service limits.
• Compression loss traced to leaking exhaust valves.
• Cylinder head rebuilds where dependable valve sealing is the goal.
