Description
2020–2027 CFMOTO ZFORCE 950 Engine Core Rebuild
Send your original ZFORCE 950 engine to REV6 for in-house inspection, machining, and rebuilding. This build-core-only service addresses the internal engine as one assembly, so the work begins after your core reaches our shop.
Our technicians determine which reusable parts remain within specification and which parts require repair or replacement. That approach keeps the rebuild tied to the actual condition of your engine instead of making assumptions before teardown.
Send Your Engine Core First
After purchase, REV6 provides the shipping instructions and tracking information needed to move your engine to our shop. Before shipment, remove the exhaust, electrical parts, fuel-system parts, and sensors from the core.
Use the REV6 engine shipping instructions to prepare the engine correctly. Our customer service team is also available if you have questions about removing external parts or arranging shipment.
