This GREHUA kit bundles the parts most likely to fix those symptoms: a 4+2 pin AC CDI box, starter solenoid relay, ignition coil, a 4-pin voltage regulator\/rectifier and two A7TC spark plugs. It’s designed to match common GY6-configured Chinese engines (139QMB, 139QMA, 152QMI, 157QMJ) found across many TaoTao, Roketa, Baja and similar models.\u003c\/p\u003e\n\n\u003ch3\u003eWhich vehicles will this GREHUA kit fit?\u003c\/h3\u003e\n\u003cp\u003eThe kit targets scooters, ATVs and small go-karts that use the GY6 family of 4-stroke engines.
