⚙️ Manufacturing Process

Yamaha follows a rigorous and proprietary OEM manufacturing process to ensure unmatched reliability and performance. Here’s an overview:

1. Casting

   • The cylinders are made using precision die-casting with an aluminum alloy, chosen for its strength, lightweight, and thermal properties.

   • The castings are cooled and solidified under controlled conditions to ensure uniformity and eliminate air pockets.

2. Machining

   • After casting, the cylinders undergo CNC machining to create precise bore dimensions, port shapes, and mating surfaces.

   • The iron sleeve is inserted and honed to a standard 64.00mm bore with tight tolerances.

3. Port Optimization

   • Factory port timing and size are retained to ensure balanced power delivery and compatibility with stock Banshee components.

   • All passages, including exhaust and intake ports, are fine-tuned for airflow and fuel atomization.

4. Cooling Channel Integration

   • Internal liquid-cooled jackets are cast into the cylinders and pressure-tested for integrity to prevent coolant leaks.

5. Quality Assurance

   • Each cylinder undergoes rigorous quality control, including dimensional checks, pressure testing, and material inspection to meet OEM specs.

   • Only parts that pass Yamaha’s standards are labeled as “Genuine OEM” and shipped for distribution.

These cylinders are the benchmark for reliability and performance in Yamaha Banshee 350 engines. Whether you’re restoring a classic or tuning for stock-level racing, OEM jugs offer unmatched compatibility, craftsmanship, and longevity.

   • Ensure the crankcase is free from debris, gasket material, and oil residue.

2. Inspect and Replace Components as Needed

   • Check the condition of your pistons, rings, wrist pins, and bearings.

   • It’s recommended to use new OEM-spec components to match the new cylinder bores.

3. Install New Base Gaskets

   • Place fresh base gaskets on the engine cases to ensure proper sealing.

4. Position the Pistons and Rings

   • Install pistons onto the connecting rods, ensuring the circlips are seated securely.

   • Compress the rings using a ring compressor or by hand, aligning them with proper end gap spacing.

5. Mount the Cylinders

   • Carefully slide the new 64.00mm OEM cylinders over the pistons.

   • Gently seat the cylinders down onto the gaskets and engine cases.

6. Torque Down Cylinder Nuts

   • Using a torque wrench, tighten all cylinder nuts in a cross pattern to Yamaha’s factory torque specifications.

7. Reassemble Top-End

   • Install the cylinder head, new head gasket, and finish the top-end rebuild.

   • Double-check coolant lines, cylinder head torquing, and compression.

8. Break-In Process

   • After assembly, follow proper break-in procedures using a recommended oil mix ratio and gradual RPM increases.

⚠️ Pro Tips:

• Always use Yamaha-approved parts to maintain OEM performance.

• Lubricate cylinder walls and pistons before installation.

• Pressure test the cooling system after assembly to ensure no leaks.

• Match your pistons to the 64.00mm standard bore for proper fitment.
