EC Banzai II .268 Cam Kit (Newly Redesigned) with 26lb Springs - Honda Clone Performance Camshaft for Kart Racing & Mini Bike Engines


Redesigned. Refined. Proven Performance.

The Banzai II .268 Camshaft is a complete redesign of our original Banzai 265—built from the ground up to meet the demands of modern Honda clone kart racing and mini bike performance engines.


In a market saturated with rebranded .265–.268 camshafts based on outdated profiles, the Banzai II stands apart with an all-new cam profile and revised timing strategy designed to deliver real-world performance gains where it matters most—below peak torque.


Built for Power Under the Curve

Most camshafts are designed to chase peak horsepower within a narrow RPM window. The Banzai II takes a different approach—focusing on average horsepower and torque across the usable powerband.

During development, we identified significant untapped power below peak torque—especially in engines running:

  • Ported cylinder heads with larger cross-sectional areas
  • Bigger valves
  • Increased airflow combinations

The Banzai II captures that lost performance, delivering:

  • Stronger acceleration
  • Improved throttle response
  • Broader, more usable power delivery

Instead of sacrificing drivability for small peak gains, this camshaft increases total power under the curve, resulting in faster, more consistent performance on track and better usability for recreational riding.


Optimized Powerband for Kart & Mini Bike Racing

  • Primary Power Range: 4500–7000 RPM
  • Secondary Power Range: 3000–7500 RPM
  • Peak Torque: 5000–5800 RPM
  • Peak Horsepower: 6500–7500 RPM

Engineered to maximize average power from 5000–7500 RPM, the Banzai II provides strong pull through corners and sustained speed on straights—without sacrificing low-end usability.


Sleeper Performance Without Complexity

The Banzai II delivers high-level performance in a non-welded “sleeper” camshaft design, making it both affordable and reliable.

  • Compatible with stock-style valvetrain components
  • Includes 26 lb valve springs
  • No exotic or high-maintenance setup required

This makes it an ideal upgrade for racers and builders who want performance without unnecessary complexity.


Recommended Engine Setup

Best suited for:

  • 212cc+ Honda clone engines
  • Compression ratio: 10:1–11:1

Fuel Recommendations:

  • Above 11:1 compression: race gas or methanol recommended


Stroker-Compatible 224-Core Design

All DynoCams 224-core camshafts feature:

  • .550” cam journal
  • Narrow lobes for rod clearance
  • Lobe-to-lobe clearancing
  • Reduced compression release for 58mm stroke compatibility

No crankshaft clearancing required, making the Banzai II ideal for stroker engine builds and high-performance combinations.


Engine Compatibility

Direct Fit:

  • Predator 224cc Non-Hemi
  • Ducar 224cc Non-Hemi
  • Wildcat 223 Hemi
  • Wildcat 240 Non-Hemi

Also Compatible (.550” Journal Engines):

  • Predator 212 Hemi
  • Tillotson 212E
  • Ducar 212
  • Honda GX200 / 196cc Clones

Important:
Stroked 196cc/212cc engines using 58mm+ crankshafts require a 224-core camshaft to avoid compression release interference.

Not Compatible:

  • Predator 212 Non-Hemi
  • Predator 224 Hemi


Camshaft Specifications

  • Lift: .268 Intake / .268 Exhaust
  • Duration @ .050: 236° / 236°
  • Centerlines: 113° Intake / 106° Exhaust
  • Recommended Valve Lash: .003–.006 (hot)
  • Includes: 26 lb valve springs


Clutch & Torque Converter Setup

  • Minimum Engagement: 3200 RPM
  • Recommended Engagement: 3800–5000 RPM
  • Max Recommended RPM: 8000 RPM

Works well with both kart racing clutches and CVT setups, including lower engagement configurations.


Recommended Performance Build

  • Engine: 236cc+, Tillotson 236R/RX, 240RX, Wildcat 240
  • Cylinder Head: WC946-3 31/25mm CNC Ported
  • Carburetor: 24–26mm (90–110 CFM), PWK24-1K
  • Ignition: SK300 flywheel with PVL 12K ignition
  • Exhaust: .960–.990 ID (open preferred)


Important Installation Notes

Due to variation in tappet lengths across engine platforms:

  • Tappets are not included
  • Inspect and measure tappets before installation
  • Replacement is recommended to ensure proper geometry and longevity


Critical Safety Requirements

  • Billet connecting rod required above 6000 RPM
  • Billet or aluminum flywheel required above 6000 RPM

Failure to upgrade rotating components may result in catastrophic engine failure.


Why Choose the Banzai II .268 Camshaft?

  • All-new cam profile—not a rebranded .265 grind
  • Increases power below peak torque
  • Maximizes average horsepower and torque
  • Broad, usable powerband for real racing conditions
  • Ideal for ported heads, big valves, and high-flow setups
  • Affordable, reliable non-welded design
  • Perfect for both kart racing and mini bike performance builds

FAQ

What makes the Banzai II .268 camshaft different from other .265/.268 cams?

The Banzai II features a completely redesigned cam profile and timing, not a rebranded grind. It focuses on increasing power below peak torque and overall average horsepower, resulting in stronger acceleration and a broader, more usable powerband.


What engines is the Banzai II camshaft best for?

It is ideal for:

  • 212cc and larger Honda clone engines
  • Predator 224, Wildcat 223/240, Ducar 224
  • Tillotson 212E and GX200-based engines

It works especially well in engines with ported heads, larger valves, and upgraded carburetors.


What RPM range does the Banzai II perform best in?

  • Primary powerband: 4500–7000 RPM
  • Secondary range: 3000–7500 RPM
  • Peak torque: 5000–5800 RPM
  • Peak horsepower: 6500–7500 RPM

This makes it ideal for both kart racing and high-performance mini bike applications.


Is this camshaft good for low-end power?

Yes. Compared to many cams in this category, the Banzai II improves power below peak torque, helping with:

  • Better corner exit acceleration
  • Improved throttle response
  • More consistent power delivery


Do I need upgraded valve springs or valvetrain components?

No major upgrades are required. The kit includes:

  • 26 lb valve springs
  • Compatibility with stock-style valvetrain components

This keeps the setup simple and cost-effective.


What compression ratio works best with this camshaft?

  • Recommended: 10:1 to 11:1
  • Above 11:1: race gas or methanol is recommended


Will this camshaft work in a stroker engine?

Yes. The Banzai II uses a 224-core design, making it compatible with 58mm stroker crankshafts without requiring crankshaft clearancing.


What clutch engagement RPM should I use?

  • Minimum: 3200 RPM
  • Recommended: 3800–5000 RPM

It works well with both kart clutches and CVT systems, including lower engagement setups.


Does this camshaft work well with ported heads and large carburetors?

Yes. The Banzai II was specifically designed to recover and improve performance in high-flow combinations, including:

  • Ported cylinder heads
  • Larger intake ports
  • Bigger valves
  • High-flow carburetors


Is this camshaft safe with stock internal engine components?

No. For operation above 6000 RPM, you must upgrade:

  • Billet connecting rod
  • Billet or aluminum flywheel

Failure to do so can result in catastrophic engine failure.


Are tappets included with the camshaft kit?

No. Due to variations in tappet lengths across engine platforms:

  • Tappets are not included
  • Inspection and proper sizing are recommended before installation


Is the Banzai II better for racing or recreational use?

It excels in both:

  • Kart racing: improved acceleration and broader powerband
  • Mini bike performance: smoother, more usable power delivery
