Benefits

Over time, reed valves naturally wear through constant opening and closing. As they lose their sealing ability, engine performance begins to suffer.

Replacing worn reed valves can help restore:

• Stable idle
• Improved throttle response
• Better engine performance
• Consistent power delivery
• Improved fuel efficiency
• Easier starting

If your NS400R has become harder to tune, is idling inconsistently, or has lost some of its crisp throttle response, worn reed valves may be the cause.

Installing a fresh set of DMR-Japan reed valves is an excellent way to restore your engine's performance and keep it running as Honda intended.

Why Replace Your Reed Valves?

As reed valves wear, they can cause:

• Reduced engine performance
• Unstable idling
• Poor throttle response
• Increased fuel consumption
• Loss of low and mid-range power

Replacing them as part of an engine rebuild or routine maintenance helps keep your two-stroke performing at its best.
