Fast blinking blinkers.

You usually see this when someone swaps out their stockers for LEDs. The LEDs have a much lower resistance rating than the standard bulbs, which is what causes the fast blinking. Figure out what the difference in resistance is and wire in a resistor inline and they will blink at the correct speed.

Incorrect load on the "blinker" relay. You can usually add a resistor to the positive lead running to your turn signal to correct it. Did you recently change to LED turn signals or something else after market? Google turn signal and resistor and I'm sure you'll get some good values to start with. Resistors can be bought for a few cents at Radio Shack.

ETA: Dammit, Mikey apparently types much faster than me.

In the car, it usually means a bulb is out.

LED blinkers have less resistance than the regular bulbs. You need to add a 5 ohm 100w resister in series for each blinker to slow down the blinking rate.

I have fast blinking blinkers due to switching the stockers for aftermarket ones. I've gotten used to it and I'm fine with it.

I know the kit came with some resisters that would reduce the flow to slow the signals down BUT they get really hot and I didn't want the additional heat since the bike is so hot anyways plus with all of the plastic on the bike.

100W? That's way overkill. I'm sure even a 25W would be plenty.

Mounting the resistor where some air will pass over it will help with any heat issues, but like z06 pointed out, I'd keep it away from plastics.

That's what came with my Clear Alternatives integrated tail light. It worked fine for me. It was a little warm but I zip tied them to part of the frame to keep them off the plastic.

I have aftermarket blinkers front and back, but I've had them on there for almost two years and the fast blinking didn't start until a bulb went out last week.

Then the bulb you used as a replacement doesn't have the same resistance as your stock ones. Same solutions apply.

It could also be a bad flasher relay.
