With a volt meter Jenya. Check voltage of battery while bike is not running. Should be over 12 volts. Then start the bike and check voltage again while slowly increasing the rpms. It should read over 13.5 volts over 3000 rpms. If the volts remain the same (12 volt range or decrease) then the problem is your charging system, (wiring, alternator and/or regulator). Others can tell you how to test them, Graham
