$125.00
$159.95

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

PCV Valve Removed: Due to customer feedback, the built-in PCV valve has been eliminated. Most users route ventilation through the valve cover or external catch can, improving clarity and function.
Optional PCV Use: You can still add a PCV valve using the top oil fill hole with a 280 valve.
Pulse Fitting Included: Use for oil recirculation or pulse-operated fuel pumps, especially when top oil holes are blocked.

Optimized Oil Fill & Dipstick Placement

Top Oil Fill Only: Improved clearance for stock fuel tanks and electric starters.
Billet Dipstick: Now located on the front—easier access for go-karts and mini bikes.
Rear Fill Hole Removed: No longer needed, reducing potential leak points and hardware complexity.
Black Anodized Finish: Prevents galling and seizing of dipstick and cap, ensuring smooth maintenance.

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:

Reduced Windage Loss
Improved Lubrication & Cooling
Slower Oil Breakdown
Better Performance from Oil Additive Packages

Enhanced Sealing & Structure

23" O-Ring Groove: Machined groove provides superior crankcase sealing over traditional gaskets.
Solid Dowel Pins (x2): Replace stock hollow pins for maximum side cover stability.
Cap Screws Included: Accepts 8Mx35 socket head cap screws, or upgrade to the optional EC Stud Kit for even greater strength and alignment.
Recommended for Use with Tillotson Reinforced Blocks

Precision Camshaft Bearing Support

Steel Cam Bearing: Outlasts aluminum or bronze bushings and reduces friction—easier to replace, too.

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.

Frequently Asked Questions

When will my order be shipped and how long does delivery take?

Orders containing in-stock items typically ship within 3–5 business days. Orders that include assembly will require 7–10 business days to prepare. Please note that during the holiday season (Thanksgiving through Christmas), processing times may be longer due to high order volume. Once your order has shipped, you’ll receive an email with tracking information. Most orders are shipped via Less Than Truckload (LTL) freight and generally arrive within 3–7 business days. Deliveries to remote areas (such as mountains, forests, valleys, or islands) may take longer. You can check the estimated delivery date on the carrier’s website using the tracking number we provide.

How your vehicle is shipped?

Unless otherwise noted, the vehicles we offer are shipped crated or on a pallet and do not come assembled unless you’ve selected our assembly service. Assembly typically requires a few basic tools and mechanical knowledge. If you're not confident in your ability to safely assemble a high-speed off-road vehicle, we strongly recommend selecting professional assembly or having it assembled by a local mechanic.

What does 95% or 98% Assembly Mean? What do I need to assemble if shipped in crate?

For shipping safety, most vehicles cannot be fully assembled prior to delivery.

Minor assembly is required—this typically includes installing mirrors, connecting the battery, adjusting handlebars, and other small components. Before operation, please ensure all screws and fasteners are tightened, engine fluids are at proper levels, and the battery is fully charged. Your factory warranty remains valid right out of the box.
