got my first bike three days ago. a 1987 honda cbr 600cc. having problems with it already. the battery is old so i just replace the bike with a new battery but for some reason its still not working. when i jump start the bike with a jumper cable it works for awhile then shut off again. plz let tell me whats wrong. thank you all

You didn't say if you charged the new battery.

Make sure you charge it for 8 hours or so before riding it the first time.

If you did, then good luck, you have an electrical problem.

There could be a few things wrong. Your new battery is loosing charge and/or is not getting recharged properly.

Try this:
Remove the battery and charge completely. Try starting - should work. Leave it on a bike and try next day. If the battery is dead - you have a short in the wiring somewhere and it's draining your battery.

If you leave the bike parked for a really long time, the battery will discharge even if your electrical system is ok.

If your battery only dies as a result of riding, and not after sitting overnight, then you have a bad charging system. You'll need to check wiring and alternator. something is broken somewhere, but it's impossible to say what and where without looking at the bike.

You need a battery charger.

Get a Battery Tender Jr., or the equivalent. They cost about $30 at Cycle Gear.

so you jump it.. it will run for a while.. and shut off?

while idling? is it a rough idle?
make sure your petcock is on all the way too.

check to see if you are low on gas as well.

Honda's eat reg./rectifiers like nobody's business, if you've tried the other things listed above, get a mulit-meter and explore. could be the stator too.

Are you serious???? :confused

You have a 12v battery, so you need a 12v charger.

[Kameron808]

Did you jump it from a running car? Don't do that.

Charge at 12v less than <2 amps for a few hours, the check your regulator/rectifier.

Stranger's right, Honda's go through reg/recs like nobody's business.

You should still check the charging system. If it's not charging, the bike will die again. It will just take a little longer since you have a fully charged battery now.
