• Dual cast iron piston rings (optional oil ring)

• Flange bearings to eliminate cylinder wear issues

• Optimized compression ratio for better spark plug durability

• Improved carburetor rotor for smoother throttle response

👉 This is an evolutionary upgrade, solving known issues from earlier generations.

3. Performance & Running Experience

LS-52

• Wider RPM range (up to 12,500 rpm)

• Dual-needle 6mm carburetor for better atomization

• MCU ignition compatibility: 

1. Automatic ignition timing adjustment
2. Faster response
3. Lower electromagnetic interference

✅ Result:

• Smoother high-speed operation

• More precise control

• Better suited for advanced users and performance tuning

V8-OHV-44 PRO

• Stable RPM range up to 10,000 rpm

• CDI ignition system (simpler, more accessible)

• Optimized low idle and throttle response

✅ Result:

• Easier startup and operation

• Reliable and predictable performance

• Ideal for entry-to-intermediate users

4. DIY Experience & Difficulty

LS-52
