Question about 2007 Hyosung GT250R
Rear cylinder working well. Swapped ignition coil and spark plug with the rear. Front still not working, rear working. Cables look good... Any possibility other than CDI? Fixed: Replaced CDI.

Hi, Anonymous and the usual suspects are:
1. Fouled spark plugs.
2. Severely discharged or a damaged battery should have 12.5 volts or more and be able to pass a proper "LOAD" test if necessary, you may have a preliminary reading of 12.5 volts or more but little or zero amperage the battery is faulty and must be replaced, AGM batteries fail in this scenario more so than lead acid batteries.
3. Check battery terminals for damage or corrosion, check the battery cables at "BOTH" ends for loose, corroded, or broken connectors, "INSIDE" and outside the cable harness, perform connector wiggle test and check cables with an ohmmeter if necessary.
4. Loose connection at ignition coil or plug between ignition sensor and module.
5. Spark plug cables in bad condition, shorting/leaking, spark plug cable connections loose check for spark leakage in the dark.
6. Faulty ignition coil or electronic control module.
7. Faulty pulse coil.
8. Faulty CKP, CMP, or BAS sensor.
9. Faulty ignition switch.
10. Tilt sensor needs a reset.
11. Security alarm failing to disarm needs reset

is this the one that kick in at a higher rpm to burn more gasses while running at speed? is it not running as it should, are you having an issue other than it doesnt do what you thought it should.No spark in rear cylinder or just on the one plug out of the two? If all is checking out as you said its got to spark.trade the coil thats on one with that other one see if the trouble is the same or moved with the coil to its new location.coil may work but not be good enough to run.
