EC Advanced Billet Side Cover – Performance Engine Upgrade for Honda GX200 & Clones
The latest version of the EC Advanced Billet Side Cover brings performance, precision, and ease of use to a new level. Designed for Honda GX200-style engines and compatible clones, this upgraded billet side cover improves durability, oil capacity, and crankcase pressure control—while simplifying installation and maintenance for serious racers and builders.
Whether you're assembling a race-ready engine or upgrading a performance mini bike, EC Carburetors' billet side cover delivers precision machining, innovative design, and race-proven functionality.
Key Features & Engineering Updates:
Redesigned Crankcase Ventilation (PCV) Setup
Optimized Oil Fill & Dipstick Placement
Maintains Full Oil Capacity
Unlike other billet covers that flatten the internal surface and reduce sump volume, EC's design retains the engine’s original oil capacity. Benefits include:
Enhanced Sealing & Structure
Precision Camshaft Bearing Support
Optional Stud Setup Instructions
If using studs, install solid dowels first to ensure proper alignment. Installing studs before seating the cover can cause misalignment and potential damage to the block or cover.

Q1: What engines is the EC Advanced Billet Side Cover compatible with?A1: This billet side cover is compatible with:
Not compatible with: Predator 212 Non-Hemi or Predator 224 Hemi.
Q2: What’s the benefit of eliminating the built-in PCV valve?A2: Based on customer feedback, the PCV valve was removed to simplify venting and allow greater flexibility. Most racers now route crankcase ventilation through the valve cover or to an external catch can. However, a PCV valve can still be added to the top fill port using a 280-style valve if needed.
Q3: Can I still use a fuel pump with this cover?A3: Yes! The included pulse fitting allows for oil recirculation or operation of a pulse-style fuel pump. This is especially useful when the top oil fill ports are blocked or rerouted.
Q4: Does this side cover reduce the engine’s oil capacity?A4: No. Unlike many billet side covers that reduce internal sump volume, this cover preserves full OEM oil capacity—helping improve cooling, lubrication, and oil longevity under racing conditions.
Q5: What if I want to use studs instead of the included bolts?A5: If using a stud kit, be sure to install the solid dowel pins first to properly align the cover. Installing studs before alignment can cause misfitment or damage to the block and cover.
Q6: What’s included with the side cover?A6: Each kit includes:
Q7: Why is the dipstick moved to the front of the cover?A7: The front-mounted dipstick offers easier access for go-karts and mini bikes, especially those with limited side clearance. This layout also improves compatibility with electric starters and stock fuel tanks.
Q8: Will this improve engine performance or reliability?A8: Absolutely. This cover offers:
