Get a heavy duty electronic flasher. Novita flashers are sold at autozone & other places. made in USA. Get one that's the same size & shape w the same number of terminals. LL552 or EL12 or etc. The old thermal flashers may not work right with modern bulbs or LEDs.
There's probably 1 flasher for the turn signals & 1 for the hazards. That's the way it is on my 81 KZ650-CSR & there are even 2 different part numbers & mine probably flash at different rates. I think your motorcycle has 2 identical flashers, same part number for both.
1981 KZ650-CSR. Competition, Sports & Road.
