And is there a certain size diode we should use? Do you know what size was used? Don't want too small and have it short like yours did at first. Thanks again!

 Most any type of Schottky Diode will work.   If you look of the specs of them you will see forward voltage like 0.xV usually. Then you will also see a reverse voltage say 30v or higher will be overkill and good. Amps here are minimal as you are only triggering a relay not supplying voltage to a light or anything. Key thing to pay attention to here if you feel the need is your reverse voltage being well beyond circuit voltage.  I didn't measure circuit voltage but it will be  likely around 5 or up to 12 in this situation.

 Out issue was a LED is a diode but known to be weak as a clocking diode in a circuit.  Some of the small ones will reverse at a very low voltage (the case we ran into)  that LED was one we de-soldered from a 15 yr old computer fan. Not a case you would likely run into . 
  Example of more than you need.  and a 50 pack of them.  lol   https://www.amazon.com/dp/B07BVKQ6WY/ref=sspa_dk_detail_0?psc=1&pd_rd_i=B07BVKQ6WY&pd_rd_w=IbTTI&pf_rd_p=45a72588-80f7-4414-9851-786f6c16d42b&pd_rd_wg=qR4BK&pf_rd_r=E6QH52Y66AA37CZZVQZC&pd_rd_r=a7953247-2e94-46cf-95bd-6404404322b1&spLa=ZW5jcnlwdGVkUXVhbGlmaWVyPUEyTFdXQkQ5N0U2MlFWJmVuY3J5cHRlZElkPUEwMTU2MjU2ODM4SkhCSEo3SFYzJmVuY3J5cHRlZEFkSWQ9QTA4NTgxNjYyM0lQOENRSFE0RTNKJndpZGdldE5hbWU9c3BfZGV0YWlsJmFjdGlvbj1jbGlja1JlZGlyZWN0JmRvTm90TG9nQ2xpY2s9dHJ1ZQ==

Are you both running stock bulbs still or HIDs/LEDs?

 LED for the low beam and stock for the high currently.

Both LED low for now and stock high. Havent even had either bike in the dark yet. Probably do the high eventually, the yellow contrast with the LED low bugs me.

I wired one of the diodes you recommended from the terminal socket on the front right corner of the right relay (looking down at the terminal block from the back of the bike) to the terminal socket on the bottom left of the left relay. Didn't work. Headlights worked normally (low beam turns off). Am Iusing the right terminals?

Need to be terminal 2 on both relays. The sockets are opposite in the bike. Make sure the diode is facing the right way too.

Thanks, I'll look for the terminal numbering tomorrow and try again. I did try the jumper connection with the diode reversed as well and got the same result, low beam turned off.

It was a little tricky to see the terminal numbers on the relays (tiny print), but the diode worked great. Haven't tried to high beam for any amount of time, but worked great in the garage testing.  I have 49 diodes leftover.  If anyone wants them, get me a mailing address and I'd be happy to put them in the mail (US only...) to you.

 Good deal man!  Glad you got it figured out.  No new wire harnesses or anything.  ;)
