This MOREV unit matches the rounded 6-pin 4+2 connector layout used on many 4-stroke horizontal GY6 engines, making it a practical swap when the original CDI is damaged or unreliable. Read on to confirm fit, learn what to check before buying, and see which models commonly use this configuration.\u003c\/p\u003e\n\n\u003ch3\u003eHow do I know this MOREV CDI will fit my engine?\u003c\/h3\u003e\n\u003cp\u003eCompatibility depends on the ignition type, connector shape, pin arrangement, and physical dimensions. This module is built for AC-fired GY6 systems with the rounded 6-pin 4+2 connector — it will not work with DC CDIs or different connector shapes.\u003c\/p\u003e\n\u003cul\u003e\n  \u003cli\u003eCheck your engine code: fits many 139QMB, 1P39QMB, 152QMI and 157QMJ applications.\u003c\/li\u003e\n  \u003cli\u003eVerify connector: rounded 6-pin 4+2 pin layout (not rectangular DC types).\u003c\/li\u003e\n  \u003cli\u003eCompare mounting hole positions and module size to ensure clearance.\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003ch3\u003eWhich scooters and go-karts commonly use this CDI?\u003c\/h3\u003e\n\u003cp\u003eThis MOREV module is compatible with a range of popular small-displacement vehicles that use GY6 AC ignition systems.

However, it won't remedy mechanical engine faults, fuel delivery issues, or electrical problems unrelated to the ignition module.\u003c\/p\u003e\n\u003cul\u003e\n  \u003cli\u003eLikely improvements: restored spark consistency, easier starts, more reliable idling.\u003c\/li\u003e\n  \u003cli\u003eNot addressed: clogged carburetors, damaged stators or coils, battery\/charging faults on DC systems.\u003c\/li\u003e\n  \u003cli\u003eDiagnostics tip: test or inspect stator and coil continuity before replacing if unsure.\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003ch3\u003eHow should I verify and install the replacement CDI safely?\u003c\/h3\u003e\n\u003cp\u003eBefore ordering, compare the connector shape and pin layout physically to your original module and review mounting points. Install with the ignition off, match wire color\/functions, and secure the module away from excessive heat or moving parts.\u003c\/p\u003e\n\u003cul\u003e\n  \u003cli\u003eTurn off fuel and ignition and disconnect the battery if present.\u003c\/li\u003e\n  \u003cli\u003eMatch 4+2 connector pins and confirm wire colors correspond to original harness.\u003c\/li\u003e\n  \u003cli\u003eMount with supplied or original fasteners; avoid contact with exhaust or sharp edges.\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003cp\u003eWho is this for: The MOREV 6-pin AC CDI is aimed at DIY mechanics, repair shops, and owners of GY6-based scooters, mopeds, go-karts and small ATVs who need a like-for-like replacement for an AC ignition CDI. It suits anyone comfortable verifying connector types and performing basic electrical swaps, and is especially helpful when the original module shows visible damage, corrosion, or intermittent performance. If you rely on accurate fitment, compare the original CDI’s connector shape, pin positions and module dimensions before purchasing to ensure a successful replacement.\u003c\/p\u003e\n\u003csection class=\"product-faq-snippet\"\u003e\u003ch3\u003eFAQ\u003c\/h3\u003e\n\u003cdiv class=\"faq-item\"\u003e\n\u003cp class=\"faq-q\"\u003eQ: Is this CDI compatible with DC ignition systems?\u003c\/p\u003e\n\u003cp class=\"faq-a\"\u003eA: No. This MOREV unit is for AC-fired GY6 ignitions with a rounded 6-pin 4+2 connector only.\u003c\/p\u003e\n\u003c\/div\u003e\n\u003cdiv class=\"faq-item\"\u003e\n\u003cp class=\"faq-q\"\u003eQ: Can I use this CDI on a 150cc GY6 engine?\u003c\/p\u003e\n\u003cp class=\"faq-a\"\u003eA: Yes, it fits many 150cc 4-stroke horizontal GY6 engines, but verify connector and engine model before buying.\u003c\/p\u003e\n\u003c\/div\u003e\u003c\/section\u003e","brand":"MOREV","offers":[{"title":"Default Title","offer_id":48084589052062,"sku":"B0G6DWH3T2","price":34.98,"currency_code":"CAD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0781\/2041\/9486\/files\/morev-front-view-cdi-module.jpg?v=1785860269","url":"https:\/\/northtrailauto.ca\/products\/morev-6-pin-ac-cdi-ignition-module-for-gy6-50cc-150cc-rounded-4-2-connector-direct-fit-replacement","provider":"North Trail Auto","version":"1.0","type":"link"}
