Premium CFMoto OEM Engines and Long Blocks: Restore Your Factory Performance - Available at buywitchdoctors.com

Product Specifications: Genuine OEM CFMoto Long Engine Block, Part 0NYV-BLB000-0840.

When your machine’s heart stops beating, settle for nothing less than a factory-fresh start. CFMoto OEM Engines and long blocks are the gold standard for riders who demand reliability and precision. Unlike rebuilt or "frankenstein" engines that rely on used casings, these genuine units are built to the exact tolerances required by the manufacturer, ensuring your UTV or ATV runs exactly like it did the day it rolled off the showroom floor.

Available at Witchdoctors.com, our CFMoto long blocks provide a comprehensive solution for catastrophic engine failure or high-mileage wear. By choosing an OEM long block, you eliminate the guesswork of individual component compatibility and significantly reduce your downtime in the shop.

The Advantage of CFMoto OEM Long Blocks

Replacing an entire engine assembly might seem like a major undertaking, but it is often the most cost-effective and reliable way to handle a major breakdown. Here is why serious riders choose OEM:

• Zero-Hour Reliability: Every long block is factory-tested to ensure compression, oil pressure, and timing are perfect.
• Complete Internal Assembly: These units typically include the crankcase, crankshaft, pistons, connecting rods, camshafts, and cylinder heads already assembled.
• Engineered Durability: Utilizing CFMoto’s proprietary alloys and heat-treatment processes for maximum thermal resistance.
• Perfect Fitment: No modifications required. All mounting points, sensor ports, and cooling passages align perfectly with your existing chassis.
• Restored Resale Value: A genuine OEM engine replacement holds significantly more value than a third-party rebuild.

Essential Engine Parts & Accessories

While a long block provides the "core" of your power, you often need supporting components to complete the installation. Witchdoctors.com carries a full suite of engine-related hardware:

• Gasket & Seal Kits: High-temp head gaskets and crankcase seals for a leak-free build.
• Oil Pumps & Water Pumps: Ensure vital fluids are circulating at the correct pressure.
• Stators & Flywheels: Restore your electrical charging system and ignition timing.
• Replacement Sensors: TMAP, CPS, and Oxygen sensors to keep your EFI running smoothly.
• Oil Filters & Service Kits: Start your new engine’s life with the highest-grade synthetic fluids.
• Engine Mounts: Heavy-duty rubber dampers to reduce vibration and prevent frame stress.

Frequently Asked Questions

What is the difference between a short block and a long block?

A short block usually only includes the bottom end (crank and pistons). A CFMoto long block includes the cylinder heads and valvetrain, making it a much more "plug-and-play" solution for engine replacement.

Does my new OEM engine come pre-oiled?

No. Most engines are shipped "dry." It is critical to prime the oil system and use the manufacturer-recommended break-in oil for the first few hours of operation.

Why choose OEM over a local engine rebuild?

Local rebuilds are limited by the quality of the machine shop. An OEM engine is built in a controlled factory environment using automated precision that local shops simply cannot replicate.
