Loved it fixed all my issues With my bike. If you’re looking for a stock carb fix this is it. Just use your stock jets and needle not the ones supplied and you’ll be good as new. I put it on and it ran lean so just use your stock rated stuff and go off from there. Fixed my throttle response and idling issues so I love it ever since. The power jet valve is awsome. You just have to rev it when it’s warming up to prime it and take off and adjust more fuel to go faster.

Junk, runs way to lean

HOW TO CHOOSE CARBURETOR

Confirm your engine type and capacity

Before ordering a carburetor, please confirm your engine is a 2-stroke or 4-stroke. And the engine capacity is also important. You can check it in the engine manual or the label on the engine.

MEASURE THE SIZE OF CARBURETOR INTERFACE

Notice the outer diameter of the engine, compare the inner diameter of the carburetor interface, and ensure the carburetor can be installed correctly. Besides, if the carburetor is a flanged port, please notice the distance between the two holes.

MEASURE THE INNER DIAMETER OF INTAKE MANIFOLD

Comparing the intake manifold inner diameter to the carburetor outer diameter, the size needs to be matched. Normally 100cc ~ 18-20mm, 200cc ~ 24-26mm, 250cc ~ 28-30mm, 300cc ~ 30mm-38mm.

CHECK FUEL DELIVERY METHOD: GRAVITY OR PUMP?

Please make sure your engine uses gravity fuel supply, normally fuel tank is located above the carburetor. Nibbi Racing carburetor is only fit for gravity fuel supply.

CONFIRM THROTTLE AND DAMPER TYPES
