My Bike is turning over, but there's no Spark (Hyosung GV125) Replaced CDI, Regulator, fuses, what is my problem?


Hi Bradley, if you have a CKP sensor it needs compression to send correct signal to the ICM/ECM, make sure both spark plugs are in heads and use a grounded third plug to check for spark or hold spark plug cable close to spark plug in head. If still not getting spark the usual suspects are:
1. Fouled spark plugs.
2. Battery voltage below 8.7 volts, loose or broken battery cables, check the "NEGATIVE" cable at both ends.
3. Loose connection at ignition coil or plug between ignition sensor and module.
4. Spark plug cables in bad condition, shorting / leaking, spark plug cable connections loose.
5. Faulty ignition coil or ignition / electronic module
6. Failed CKP, CMP, MAP or BAS sensor.
7. Faulty ignition switch.
8. Security alarm failing to disarm.

Got a hyosung gv250 that wont run..just cleaned the carbs and fuel is making it to the carb...im thinkin it could be it not getting spark...any ideas?


Not sure if this is still an issue as it's an old post but have you tried checking for a spark?

-Take your spark plug out,
-attach the ht lead to it,
-Hold it with a pair of INSULATED pliers so that the metal tip of the spark plug is earthing by touching it to some bare metal e.g. the cylinder head,
-Crank the engine and look for a spark. (Be careful about earthing it near the hole in the head where the spark plug fits as there may be petrol vapour present which may ignite).
Do this for both cylinders
