Why Proper Jet Ski & WaveRunner Keihin CDCV Carburetor High Speed Main Jets Matter

Ensure your Jet Ski or WaveRunner runs at peak performance with correctly sized low‑speed pilot carburetor jets. Proper jetting delivers smooth idle, crisp throttle response, strong acceleration, and safe engine temperatures—protecting your engine from lean burn, detonation, and premature wear.

Use Only Genuine Keihin CDCV Jets

Precision matters. Genuine jets are manufactured to exact flow specifications, ensuring accurate fuel delivery and consistent tuning results. Unlike aftermarket copies, authentic Keihin CDCV high speed main jets offer:

  • Perfect fit and reliable metering
  • Consistent orifice sizing
  • OEM‑level performance and durability
  • Safe operation under high RPM and heavy load

Whether you’re rebuilding a single carb or tuning a full triple‑carb setup, genuine jets provide the accuracy your watercraft was designed for.

Atlantic Jet Sports supplies 100% Genuine Keihin carburetor jets, rebuild kits, and tuning components—never aftermarket copies. Whether you’re rebuilding a single carb or dialing in a full triple‑carb setup, using authentic parts ensures your watercraft performs exactly as the manufacturer intended.
