When i installed the led signals on the 250, (now michas 250) not all the leds would light up no matter how much i reved... And after a week or so they "broke in" so that they all worked... I never replaced the flasher unit, so they would be all on or all off... But i thought those lights were the best thing i did for that bike

Normal light bulbs will simply be dimmer under less voltage. LEDs may simply not light at all. LEDs require very little current - so unless they are equipped with a resistor that adds additional load, the load on the charging system shouldn't have increased that much. To prove that its the voltage being put out by the charging system do this: Take a voltmeter - preferably digital - and measure the starting voltage of the battery. Fire the bike up. Take note of the voltage of the battery with the bike idling. It shouldn't be remarkably different from the pre-starting voltage. Hold the throttle open so the engine revs up to approximately 2,000 RPM and hold there. Measure the voltage again. You should see an increase of a couple volts. Now - release the throttle. Turn on the blinkers - you'll see that the voltage drops as the lights turn on each time. Open the throttle back up to hold at 2,000 RPM and measure the voltage with the blinkers on. You should see that although their might be a variance between lights on and off, the difference should be much smaller than the engine idling. This simply means that the charging system is providing electricity to the electrical system on the bike instead of drawing it from the battery. With the throttle open, you should see all the LEDs blinking. The only 'cure' for this is to reduce the load on the electrical system so the voltage drop from the blinkers turning on is lower. This is one of the advantages of an all LED system - but you must replace the flasher unit at the same time, otherwise they will fail to blink because the existing system is load based. No / less load, no blinking.
