Billet Intake Adapter for PWK Carburetors – Fits Honda GX200 / Clone Engines

The EC 472INT Billet Aluminum Intake Manifold is engineered to adapt PWK-style spigot-mounted carburetors (24mm to 28mm) to Honda GX200 and 196cc clone engines. Whether you're building a high-performance mini bike, kart, or race engine, this intake offers the precision, strength, and features enthusiasts and racers demand.

Precision Fit & Performance Design

Unlike low-cost cast intakes with generic shapes, this adapter is CNC-machined to match the D-shaped intake port common on GX200-style cylinder heads. However, due to manufacturing variations and aftermarket porting, some heads may require minor port matching for a perfect seal — especially Hemi heads or modified castings.

Built for Durability & Secure Mounting

Where other intakes fail to hold the carburetor under high vibration or aggressive riding, the 472INT shines:

• Carb Boot Locking Groove: Precision-machined groove ensures a tight, secure grip with the recommended rubber carb boot (#515 – sold separately).

• Stabilizer Bracket: A custom-fit bracket bolts the intake to the carburetor, preventing accidental separation — ideal for trail riding, mini bikes, or racing applications.

• Pulse Fitting Included: Supports vacuum-operated fuel pumps for reliable fuel delivery at all RPMs.

Application Compatibility

Designed to fit most GX200-style small block engines, including:

• Honda GX200 / 196cc Clone Engines

• Box Stock Project 196

• Tillotson 196R / 212 / 225 / 228 / 236 / 268

• Ducar 196 / 212 / 224

• Predator 212 (Hemi & Non-Hemi)

• Predator 224

• Wildcat 223 / 240

• Ghost 212

Note: Hemi heads(especially Ducar/Tillotson/Ghost) often have slightly offset ports. Fitment is not an issue, but port matching may be necessary for optimal airflow.

FAQ

Q1: Will this intake fit my Predator 212 engine?

Yes, it fits both Hemi and Non-Hemi versions of the Predator 212. However, Hemi heads may have a slightly offset intake port, so we recommend port-matching for optimal performance.

Q2: What size PWK carburetors does this adapter support?

This intake supports 24mm to 28mm PWK-style spigot-mount carburetors. Always verify the spigot outer diameter (OD ~34.95mm) and inner diameter before installation.

Q3: Do I need the carburetor boot (#515)?

Yes. The carb boot (#515, sold separately) is essential for securely attaching the carburetor to the intake. The intake features a locking groove designed specifically for this boot.

Q4: Is a fuel pump required?

Not always, but if you're running a fuel system that requires vacuum assistance, the intake includes a pulse fitting to connect a fuel pump.

Q5: Will this fit a stock Honda GX200 engine?

Yes, it fits stock GX200 heads and most clone variants. For original Honda heads, ensure the intake port shape matches or be prepared to port match slightly for a precision fit.

Q6: Does this come with everything I need for installation?

The kit includes:

• Billet intake manifold

• Gasket

• Mounting bolts

• Carburetor stabilizer bracket with hardware

• Pulse fitting

You will still need a carburetor boot (#515) and potentially a tap (#10-24) for bracket mounting.

Q7: Can this be used for racing or trail riding?

Absolutely. The stabilizer bracket prevents carburetor separation under harsh vibration, making it suitable for mini bikes, karts, and high-performance race builds.

Q8: Can I use other brands of PWK carburetors?

Yes, but since spigot diameters vary slightly between brands and knock-offs, always check your carb's OD and ID to ensure proper fit — or use EC's PWK carb kits for guaranteed compatibility.
