JC Racing Honda Ruckus / Metropolitan Carb Kit 50cc

Upgrade Your Honda Ruckus / Metropolitan with More Power & Performance

Looking for more acceleration and power from your Honda Ruckus/Metropolitan, or need to replace a worn-out stock carburetor? This is the solution. Designed by JC Racing, this is one of the most complete carburetor kits available and the original to feature a solid aluminum intake manifold—built specifically for the Honda Ruckus and Metropolitan.

Designed and tested specifically for Honda Ruckus and Metropolitan platforms, this kit utilizes improved flow characteristics from a larger 19mm carburetor (stock is only 15mm), delivering noticeable gains in throttle response and overall performance. It’s especially beneficial when adding aftermarket exhausts, head porting, performance camshafts, etc., which almost always require rejetting. With this kit, you get a full range of jets, making tuning simple and precise—no more hunting for hard-to-find stock carb jets.

Key Features:

• Solid aluminum intake manifold (eliminates common failures from rubber mounts)

• Pre-configured Nibbi 19mm carburetor for easy installation on Ruckus/Metropolitan

• Increased airflow, throttle response, and overall power

• Complete jet kits included for precise tuning across stock and modified setups

• High-flow foam air filter replaces restrictive factory airbox

Compatibility:

• Honda Ruckus (2003 and newer)

• Honda Metropolitan (2003–2014) (requires slight throttle cable clearance near storage area)

What’s Included:

• Solid mount aluminum intake manifold

• Storage box for jets and small parts

• All required O-rings and gaskets

• Nibbi 19mm carburetor

• High-flow foam air filter

• Throttle cable

• Stainless steel mounting bolts and flange nuts

• Main jet set: 78, 80, 82, 90, 92, 95, 98, 100

• Pilot jet set: 30, 32, 35, 38, 40

This all-in-one kit gives you everything needed to upgrade, tune, and maximize your scooter’s performance—whether you're running stock or heavily modified.
