Honda NAVi Upgraded carb kit

The Details ⚙️

Be one of the first to properly wake up your Honda Navi with this complete performance carburetor kit. Designed to increase airflow and improve throttle response, this setup has shown gains of nearly +2 rear-wheel horsepower when tuned correctly.

Centered around the Polini CP 21mm carb and a 2TR Made-in-USA adapter, this kit gives you everything needed to convert from the restrictive stock setup to a true performance configuration.

Paired with a full range of jets and a UNI performance filter, you’ll have the flexibility to dial in your tune for your exact setup — whether you’re stock or running additional mods.

More air + more fuel = real power gains 🔥

What's Included 📦

• 🇺🇸 2TR carb adapter (Made in USA)
• 🌀 Polini CP 21mm carburetor
• 🎯 S23 pilot jet kit
• 📏 Main jet kit (wide range of sizes)
• 🧼 UNI performance air filter
• 🔧 Choice of: choke cable + adapter or choke knob only
• 🪝 Throttle cable

Important Things to Note 🚨

• This carb must be properly jetted and tuned — incorrect setup or air leaks will cause poor performance.
• Expect to spend time dialing in your tune depending on elevation, mods, and riding style.
• If you only need the adapter for a CP/Dell’Orto carb, it is available separately.
• Do NOT stack air filter adapters — the filter will not seat correctly and may fall off.
