SOURCE: No spark

Check the side stand kill switch if your bike has one. It kills the engine so that you don’t start out with the side stand down. If broken or out of adjustment, it would kill the spark. Check for a broken wire at the side stand switch and coupler. Try moving the kill switch by hand. If that doesn’t work then wire a jumper around the switch to bypass it. Check the fuses. How good is the battery? Try a jump start from your car battery. Is the handlebar kill switch on? Check the operation of the ignition switch and all kill switches with a volt ohmmeter. Install new spark plug.

If that doesn't do it, check the wiring harness. Did a wire come unplugged? Are all wires clean and with solid connections? Any abraded or pinched wires? Is the bike in neutral and the neutral light is lit up? If no neutral light, check the neutral switch and neutral switch wire on center casing. If still no spark, get CDI system and coils checked at the dealers shop. You can screw up a CDI unit checking it yourself.

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. Faulty run/off switch
11. Tilt sensor needs a reset.

Gsxr 750 no spark how do i test cdi


I've this data from my 1986 engine!

Under the left hand side cover there are 2 2-wire connections. One with a green and a black wire, one with a blue and a yellow wire.
Use an ohmmeter at R x 100 between both wires of a connector to check the pick-up coils: resistance must be between 130 and 180 Ohms.

The values of the ignition coil resistances are:
primary coil : 3-5ohms ( set ohmmeter at R x 1 )
Secundary coil : 25.000 - 45.000 ohms ( set ohmmeter at R x 1.000 )
For a correct measurement ALL leads must be disconnected ( also the spark plug leads )

The CDI cannot be tested with a simple measurement. Suzuki dealers have a special tool to test CDI boxes.
But checking the pick-up coils and ignition coils good will indicate an defective CDI.

The wires on the CDI:
Blue: PU coil 1 ( cyl 1-4 )
Yellow: PU coil 1
Green: PU coil 2 ( cyl 2-3 )
Blue : PU coil 2
Orange/white : +12v ign coil 1-4
White : switched coil negative side ign coil 1-4
Orange/white : +12v ign coil 2-3
Blue/yellow: switched coil negative side ign coil 1-4 ( and signal to tachometer )
Blue/white : ground

Thus, you must have +12V on both Orange/white leads.
