Indicator relay

Where is it as got an mot and my blinkers are flashing too fast now and again but there's no led bulbs on it.

Just noticed that it only happens when its running it's fine with the engine off.

Check all other bulbs, normally happens when one is faulty.

It's behind the left hand black side panel.

Yes I did find it but I'm puzzled by why it only happens when its running

Just replace it - No idea why it does it when it's running but it's obviously not working right.
I fitted an adjustable flash rate relay which was cheap cos I waited 4 weeks for it to arrive from China but there are some in the UK, just a bit dearer. You might have to make up a couple of wires with spade end connectors as mine didn't fit directly onto my Fazer 1000.

Possibly regulator

I had the same problem when I first got my Fazer. Turns out bulbs with the wrong wattage where fitted in the aftermarket blinkers.
New bulbs of the correct rating solved the problem. With bayonet bulbs, anything other than 21W will affect the blinking rate.

Flashing too fast when the engine is running is down to the slightly higher voltage when using the incorrect wattage bulb. It could be a bulb that has failed and "re-made" itself.

you might be able to pin it down to one side btu its an easy and cheap job to replace all 4. The relay is behind the left side panel. You should replace that with an LED specific one if you have fitted LED bulbs
