Hi, Dan 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. A 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.
12. Security alarm failing to disarm needs reset

I don't know the bike but I doubt it is much different in principle than many others. The first possibility to consider is whether any immobiliser is functioning properly and is being properly disarmed before attempting to start. The owner's handbook would be a good place to begin...

Once you know the immobiliser is disarmed and power is flowing to the parts it is supposed to flow to, using the circuit diagram, the various supplies and grounds can be checked and using an oscilloscope check the output from the various sensors as applicable (crankshaft, camshaft).

Even though the bike has never been outside it might not have been immune from the effects of damp and condensation that can defeat many moisture barriers. It isn't unusual for electronic unit and sensor terminals to become dull, oxide coated and a barrier to current flow...

Check the fuses. Is the kill switch on or shorting out? Disconnect it and then check for spark. Sidestand/centerstand should be up, Got a good battery?

I am unfamiliar with your Keeway and just trying to help. Don't give me a bad rating if I miss the mark on this one. Thanks.

SOURCE: bike only fires once

Okay, let's have a look at it. Say Ahaaa.
The probable cause of the problem is not the spark. Get a fresh set of Stock NGK spark plugs, ground the plus to the engine, and check each cylinder for spark as the starter button is pressed for 3 seconds or so. I will wager that the spark is present.

The likely problem is the fresh gas was put into a very rusty gas tank. Bits of rust now inhabit your carb and are having fun plugging up the carb. Look at the gas valve. With a little luck there is a small bowl behind the valve. Remove it and tell me what you see in the bowl.

I would check for compression on the cylinders. a engine has to have fuel,fire and compression or it wont run. Check the specs to get the operable compression levels.

SOURCE: Battery will not hold charge after being charged. bike sat for yr

ck the chargingrate at the posts. Should be between 13.6 to 14.2. This is assuming the battery was properly filled with acid and charge before placing into service. The lower the voltage, the higher the amps. 12.0 max charging, 14.2v no charging good luck

No spark already replaced coil an brain box


Hi, Mike if you have a CKP sensor it needs compression to send the 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 the head. If still not getting spark the usual suspects are:
1. Fouled spark plugs.
2. Discharged battery, 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.
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, or BAS sensor.
7. Faulty ignition switch.
8. Security alarm failing to disarm needs reset

Will not fire a spark


Hi,
My first thought is the plug wire. You can check it by connecting an ohmmeter to each end and measure the resistance. If the meter pegs, then the cable is bad. Another is to make sure you are getting juice to and through the ignition switch. If it sat outside, the weather may have ruined the switch. Check all your wiring and make sure there are not any breaks. I have seen rodents take up residence in carts, motorcycles, snowmobiles, and ruin an entire electrical system. Let me know if I can be of more help.
