1990 Kawasaki ZX10, Bike will stall and then won't start again unless I jump it with my car. Then starts fine. Runs for a 5-10 minutes then if I come to a stop and the bike idles it will die and I can't restart off the batt with out a jump. Battery or something else? You decide. Does a bike have an alternator like a car? How does the battery recharge after start?

Before we all start guessing make sure the batt. has a full charge on it. You will need a battery tender or a low powerd trickle charger to do this. The bikes altenator isnt strong enough to do it by itself. Most likely its time for a new batt. after that you will need to check the alt. output and the voltage regulator operation.

That was quick! I got the battery about 6 months ago at walmart. How can I check the alternator output and voltage regulater?
Thanks for the help.

Let me ask this another way. Is there anything with the battery that would cause the bike to stall after running for a few minutes or at idle, if the battery is dead?

If that's the case, there is a very good chance the regulator/rectifier is bad. That's one of things my VFR would do when I had R/R problems. It will either over or undercharge the battery, sometimes both at different time. This destroys the battery.

Definately not worth buying a new one, over $200. If you can get one off ebay for $5 do that. Unfortunately a ZX10's r/r is quite different than most, otherwise I'd let you try some spares I have lying around.


Nearly forgot, it's a "chicken or the egg" sort of thing too. Either one going bad (r/r or battery) can cause the other to fail.

Wally world doesnt know that generally " a bike batt needs a full charge before an install" Some bikes like an Aspencade or big azz tour bike can do it but, most will never charge a battery, they just sell em.

I'de (not that this is right ... but I tryin to help ... so take this in a measured way):

1) Take the battery to NAPA or Autozone and have it tested "under load" that should tell you if you need a new one (if it's "flat dead").

2) Now, that does not necessarily solve your problem. If your charging system is bad ... you have only cured a symptom ... not the problem. You will know quick, too. If your new battery goes bad in 3 days .... or 1 month ... that means it's not getting recharged.

3) So, from here ... if you still have a problem it's most likely voltage regulator or rest of charging system ... rocket physics to me ... so ... get real help.

This sound right to everybody?

i'd be pretty sure its a rectifier if the battery dies that quickly.
contact the guys at www.cycleoutlet.com if you cant find anything...they sometimes have really good prices. i got a rectifier for my secaII for $42 shipped.

that CAN be a culprit but the key is it dies at idle and that he cannot start without jump/pop starting it and after its been running for 10-15 minutes .
ie when the bike is running, its not charging the battery.
and since a carb bike can still run at idle with a dead battery it basically points towards the rectifier.

Thanx Steve but I will wait for a warm day (could be March before that happens).

Nope carbs are as clean as they can get. Spent two days tearing them apart and cleaning the gunk out. The bike will start just fine if there is power.
