How long did you charge the new battery before you ran the bike?

I'd have given it a minimum of 6 hours on a trickle-charger.

If you did this then you have got a problem with your charging system as Yeskimoe said, although i've not seen reg/recs give trouble on big Kawis.

Get the battery fully charged again then...

..put a voltmeter across your battery (red to positive, black to negative, 20V DC range)) and rev the bike to 4000 rpm, you should show around 14.5 volts, much less than this and the charging circuit is suspect.

The alternator belt might need tensioning.

Try checking your charging system. i would start with regulator/rectifier. they're common to go out.

1993 Kawasaki ZXR 750 quits running while riding


Hi, Anonymous and the usual suspects are:
1. 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.
2. Failed alternator/generator and or voltage regulator.
3. Loose or corroded battery terminals and or cables especially the "NEGATIVE" cable, look for loose, corroded, or broken connectors inside the cable harness at "BOTH" ends.
4. Failed main circuit breaker or ignition switch, check for loose connections and continuity.
5. Failed system and or ignition relay, check for continuity.
6. Failed ignition coil, stator, magneto, ignition/electronic module.
7. Failed CKP, CPS, CMP, MAP, TPS, or BAS sensor, corroded, loose or broken wire connector pins/sockets.
8. Throttle cables and or idle speed improperly adjusted hot idle speed should be 950 RPM to 1000 RPM.
9. Faulty neutral, side stand or clutch lever safety switch.
10. Faulty or corroded kill switch.
11. Accelerator pump damaged or not working.
12. Water or dirt in the fuel system, carburetor or filter.
13. Restricted, blocked or kinked fuel line.
14. Fuel tank empty.
15. The gas cap is not venting properly or fuel tank venting system blocked, loosen gas cap and go for a test ride.
16. A failed fuel pump, pressure regulator and or fuel injectors.
17. Vacuum line from intake manifold to petcock broken, cracked, or not attached, carburetor vent line plugged.
18. Needle and seat stuck closed in the float bowl.
19. Petcock clogged or damaged.
20. Lean angle switch is faulty or needs adjustment.
21. Catastrophic engine failure, perform a compression test.

Carburetor?


Try cleaning the carbs. Does the engine run any better with the choke on? If so the carbs need cleaning.

1993 Kawasaki 750R - Model M , charging issue - WEIRD !!!


Hi and welcome to FixYa,

Initially, have you checked the 30 Amps main fuse and its holder clips? It would be integrated with the starter relay. The fuse or the fuse holder may have heat related problem(s) causing it to loose conductivity when hot.The fuse may require replacement even if it tests good and/or the fuse holder would need cleaning / crimping. To locate the starter relay (main fuse), follow the battery cable from the + terminal of the battery.

Please postback results.

Good luck and thank you for asking FixYa.

1993 Kawasaki 750R - Charging issue - Weird!!!


i know this sounds silly ,but when you bought the battery had it been activated,new batterys are critical in their first charge and you cannot use a standare type automotve charger,if bought dry the battery needs to have the acid filled ,left to sit for at least 2 hours prior to charging,once it has sat for the 2 hrs with the acid in,the new battery will need to be charged with a "cteck"or similar type charger for at least 13 hrs before it can be put into normal service,what happened with yours i think is that sure you gave it a charge but it has only recieved a "surface charge"and will be usable for a very short time,it may recover for a brief period and go again untill the surface charge dissipates,(or in other words ..runs out of charge)best thing you can do with the battery is take it to a auto electrician and have the battery cycled and conditioned,this is not expensive to do and will give you piece of mind,after conditioning the battery shouldngive excellent service,i have the battery in my goldwing coditioned about every 12 months and i have the same battery that was in the bike when i bought the bike 8 years ago and still no electrical or battery problems(costs about $25 to get it done)once a year but that beats $280 for a new one...hope this helps
