I had my rear blinker on my first gen blow out the other 3 were good to go...

The remaining should continue working but the OEM thermal relay will probably speed up the pulse due to the lesser voltage draw. That's an indicator of a bad indicator!

Thats what I thought. This is for my Z1k though (Z1k forums are slow). I put LED blinkers on the front and they all stayed lit except one rear blinker which is a bulb not LED. Attempted to remove it and it broke due to rust. Dont know if they are staying lit cause of that one bulb or cause of the new LEDs that I might've messed up.

LED's draw a tiny fraction of what a conventional incandescent bulb draws. The OEM Thermal relays will not work with LED's and cause them to always blink very fast or possibly stay on.

Rather than all the BS wiring of resistors and what not as recommended by most that run LED's, just buy a new $15 signal relay that no longer works on thermal principle but solid state instead. I run a VFX Relay on mine. Easy to wire in, too.

I knew LEDs would blink faster due to less draw...but I totally forgot that sometimes they draw so little that the fast blinking is so fast it turns into being solidly lit. Duh. I ran into that working on a friends bike. I knew it was something simple I overlooked.

I'm cheap so resistors would be the way to go (since its mere pocket change). Anyone recommend what kind of resistor to bring back the blink rate to almost normal?

simple, just figure out the resistance of the original bulb. You know the wattage and the voltage (12V). Then, figure out the resistance of the LED, and add a resistor in series that will bring it back to whatever the original bulb resistance was. Just remember to get resistors that will actually handle the wattage, or they may melt.
