Thanks Redz, (youll get my vote for you lol) let me be more specific, i have flushmounts turn signal with an incandescent bulb, so theres no leds. In the rear i have a led turn signal (btw i dont like them, they came with the bike when i bought her) and i just put a homemadeled turn signals in the air ducts. All this came to my head cause i want also to put hazard lights to my bike and the stock flasher saids "4 bulbs max" and that's why i want to change it to the heavy duty flasher.

Hope you understand me...

 

Yea i get it, it should flash regardless, thats weird that it doesnt. Connect just the flush mounts and the rear and see if it flashes. Even with one regular bulb on each side, it should be enough of a load for any flasher relay i would think
