Triple Engine, Triple Power: Florian Hauser’s Vintage Build Fueled by Nibbi Racing PWK24 Carburetors
When it comes to custom builds, few projects capture the spirit of creativity and engineering like the one crafted by Florian Hauser from Austria. Through his workshop, f84 engineering, Florian built a one-of-a-kind three-cylinder, 2-stroke retro moped that combines retro aesthetics with bold technical innovation.
And at the heart of this spectacular build are three Nibbi Racing PWK24 carburetors, delivering the precise fuel and air flow that make this custom engine truly come alive.
A Three-Cylinder 2-Stroke Engine
At the center of this unique machine is a custom-built 255cc triple-cylinder engine, made by combining three Avenger 85cc units.
Key highlights include:
- Three Avenger 85cc engines combined → 255cc displacement
- Custom crankshaft design with firing order 1-3-2, inspired by the legendary Kawasaki H2 750
- Approx. 25 horsepower at 12,000 rpm
- Counter-rotating crankshaft for smoother operation at high revs
This configuration delivers raw power while keeping the lightweight and aggressive character that makes two-strokes so thrilling.
Nibbi PWK24 Carburetor Was the Perfect Choice
Building a custom triple-cylinder 2-stroke requires a carburetor system that can keep up with extreme performance demands. That’s why Florian chose three Nibbi PWK24 flat slide carburetors — the perfect match for his creation.
PWK24 Technical Advantages
- Flat Slide Design → Reduces air turbulence for quicker throttle response
- 24mm Venturi Size → Balances intake speed and airflow for optimal mid-to-high RPM performance
- Superior Fuel Atomization → Delivers consistent and efficient combustion
- Durable Build → High-quality aluminum alloy with anodized finish, designed for racing environments
- Easy Tuning Options → Adjustable main jets, idle settings, and pilot jets for maximum flexibility
Role in the Triple Engine
- Each cylinder runs independently with its own PWK24, ensuring consistent fuel delivery at 12,000 rpm
- Improved throttle responsiveness across the entire rev range
- Stable performance even in an unconventional triple-engine setup
- Works seamlessly with the custom 3-in-3 exhaust system to maximize output
With the PWK24, Florian was able to unlock the full potential of his triple-cylinder build — proof that Nibbi Racing carburetors are trusted not only on standard motorcycles, but also in extreme, one-of-a-kind engineering projects.
