Description

DynoCams CS-224 Camshaft for Predator 224 & Wildcat 223 Engines


The DynoCams CS-224 camshaft is engineered for builders who want strong low-RPM torque, smooth drivability, and reliable mid-range power from their Predator 224cc and Wildcat 223 engines—without sacrificing idle quality or trail manners.


Designed around the unique requirements of 58mm stroke 224cc platforms, the CS-224 delivers a broad, usable powerband from 2,500–7,000 RPM, making it an excellent choice for trail riding, cruising, and performance builds that see both part-throttle and full-throttle operation.


Power Characteristics & Performance

  • Excellent low-speed torque with near-stock idle quality
  • Strong, smooth power delivery through the mid-range
  • Predictable throttle response for trail and recreational use
  • Optimized for reliability in extended RPM operation


This cam pairs very well with the WC946-2 cylinder head, and performs even better when matched with the WC946-3 head and PE22 carburetor, unlocking a wider and more aggressive powerband while maintaining driveability.

RPM Note:
For sustained operation above 6,000 RPM, a billet connecting rod and billet flywheel are required.


Purpose-Built 224cc Camshaft Design

Unlike reworked 196/212 cam cores, the CS-224 is built on a true 224cc cam core with .550” journals, ensuring proper clearance and reliability when used with 58mm stroke crankshafts.

Key design features include:

  • Narrowed cam lobes for improved rod clearance
  • Cleared lobe spacing to accommodate 58mm stroke assemblies
  • Thinner compression release to prevent counterweight interference

These features eliminate the need to clearance the crankshaft—an issue commonly encountered when using 196/212 cam cores in stroked engines.


Engine Compatibility

Direct Fit Applications:

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

Also Fits Engines with .550” Cam Journals:

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

Important:
When stroking 196cc or 212cc engines with 58mm or longer crankshafts, a 224-core camshaft is required to avoid compression release interference.

Doesn’t fit:

  • Predator 212 Non-hemi
  • Predator 224 Hemi

FAQ

What engines does the DynoCams CS-224 camshaft fit?

The CS-224 camshaft fits:

  • Harbor Freight Predator 224cc (Non-Hemi)
  • Ducar 224cc Non-Hemi
  • Wildcat 223 Hemi
  • Wildcat 240 Non-Hemi
  • Engines using a .550” cam journal, including:
    • Predator 212 Hemi
    • Tillotson 212E
    • Ducar 212
    • Honda GX200 / Clone 196cc

It is especially recommended for engines using 58mm or longer stroke crankshafts.


Why should I use a 224cc cam core instead of a 212/196 cam?

When stroking a 196cc or 212cc engine with a 58mm or longer crankshaft, a 224cc cam core is required.
Standard 196/212 cam cores may cause interference with the compression release, requiring crankshaft clearancing. The CS-224 is already designed to avoid this issue.


What type of performance does the CS-224 cam deliver?

The CS-224 grind provides:

  • Strong low-RPM torque
  • Smooth, near-stock idle
  • Broad powerband from 2,500–7,000 RPM
  • Excellent drivability for trail riding, cruising, and kart applications

This makes it ideal for engines that see both part-throttle and wide-open throttle use.


What is the maximum RPM for the CS-224 camshaft?

The recommended Target RPM is 7,000.
For operation above 6,000 RPM, a billet connecting rod and billet flywheel are required for safety and reliability.


What valve springs should be used with this cam?

Recommended valve spring pressure:

  • 18 lbs intake
  • 18 lbs exhaust

Stiffer Valve Springs may be require for larger than stock valves and ratio rockers


What valve lash should be set for the CS-224 cam?

Recommended valve lash:

  • Intake: .003”
  • Exhaust: .003”

Always set lash with the engine cold.


Is this camshaft compatible with stroker crankshafts?

Yes. The CS-224 camshaft is specifically clearanced between the lobes and features:

  • Narrow lobes
  • Thinner compression release
  • Proper rod and crank counterweight clearance

This makes it fully compatible with 58mm stroke crankshafts without additional clearancing.


What cylinder heads and carburetors work best with this cam?

For best performance, pair the CS-224 cam with:

  • WC946-2 cylinder head
  • WC946-3 cylinder head (best overall results)
  • PE22 carburetor

This combination delivers a strong, usable powerband with excellent throttle response.


Is the CS-224 cam good for trail riding or mini bikes?

Yes. The CS-224 is an excellent choice for:

  • Trail riding
  • Mini bikes
  • Recreational builds
  • Mild performance kart engines

Its smooth idle and strong low-end torque make it easy to ride while still delivering solid top-end power.


Does this cam work in Hemi and Non-Hemi engines?

Yes. The CS-224 camshaft works in both Hemi and Non-Hemi engines, as long as the engine uses a .550” cam journal.


Is this cam legal for racing classes?

Class legality depends on the organization and ruleset. Always verify camshaft legality with your specific series before racing.
