2005 Kawasaki Ninja ex250 Battery is fully dead in bike will not stay on Unless I have a charger on it Does the battery has to do something with it Or does the bike Do not put out current to keep itself running ?

SOURCE: my 1990 750 kawaski ninja will not charge

dear daniel first thing to do is to test your battery make sure it isup to stuff. second you must find out if your alternator is puting out. you must find the rectifier it looks like a air cooled small box. it is ususually exposed to the air for cooling. you must find the alt output wire leading to this box and test it with a volt meter it should red 12.4-12.7 this will tell you your alt is fine and your rect is at fault. be sure to check the easy stuff first like fuses, dirty batt posts ect.

sorry to say it but the battery cannot handle the load, it may work with small things like lights and low amperage devices. but when you crank the starter motor your pulling far to many amps and the battery cannot put out meaning that the battery has a bad cell or it may just need a battery refill, today we just replace the batteries. it;s safer and a lot easier. plus you get money back for bringing in your old one. but the battery is not able to supply the proper voltage and amps anymore and should be replaced. a very simple test turn the key to run and turn your headlights on. then press the starter button see if the lights do not completely go out. if they do you have a dead battery cell. good luck with it, and thanks for using fixya

SOURCE: charged battery.showed charged right away.bike wont start unless

Hi and welcome to FixYa,

The description "...series of clicks..." is significant. The battery is not putting out enough current to turn the starter motor. The best way to determine the battery condition is to have it load tested. However, considering eveything else, it would almost always be a failed or about to fail battery.

Incidentally, the alarm has been designed to have minimal current drain when in standby.

Good luck and thank you for asking FixYa.

SOURCE: How to increase top end speed - 2007 Kawasaki Ninja EX250R

you can change the sprockets.If you go to a 16 tooth front sprocket. two teeth on a front sprocket is like droping 4 teeth on the rear. You could drop 2 teeth on the rear sprocket but a 43 tooth is probably harder to find. the usual choices for front are 14,15,16 tooth.
For the rear they are 44,45,46 tooth

The way to remeber gearing changes is on REAR sprocket is smaller=faster and larger=slower top end.
the FRONT is OPPOSITE to the rear smaller=slower and bigger=faster.
You may have to lengthen or shorten the chain depending whjch way you go.

Put a charger on the battery for two or three hours. Now start the bike up and use a voltmeter to measure the voltage across the two battery terminals while the engine is running around 2000 rpm. The meter should read around 14 volts. If not, the charging system needs to be checked. If the charging system is working properly then yes, something is draining the battery. You will need to check all the wiring and switches to locate the source.
