Cuts off when riding after 20 minutes battery will completely die while riding. New stator, battery and rectifier.

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.

I had the same problem with my 900 that I just bought, the regulator was fried, so the local kaw shop replaced it with a new one off internet, then it promptly fried the new one, upon further investigation the rotor/armature was reading 1 ohm resistance, supposed toread 4/7 i think anyway, had to have alternater rebuilt , cost 370.00 , works fine now.

useing a multimeter set to d.c check your charge at the battery whith out the motor running it should read above 12 volts determine the voltage stored in the battery with the meter stil conected hit the start button if the meter shows a dramatic drop in voltage its almost certain that the battery is shot howevwer if the voltage does not drop & it wont start bump start it conect the meter still set on dc increase the revs asyou do this the voltage should climb to 13.50 if it does & maintains 13.50 to 13.65 the chargeing system can be declared ok & you only need replace the battery however if it goes above 14 volts the voltage regulator is faulty & cooking the battery so you will need to replace both

Hi,,,if your battery is not charging and you have a rebuilt staor,,then your regulator/rectifier is the cause,,its job is to charge the battery.

You need to check the charging current and also the discharging of the battery in the IDLE mode. http://www.fixya.com/cars/r5824824-draining_car_battery_charge Use a multimeter to check the charging current and also discharging rate when the engine is switched off. The alternator and accessories must be checked.
