CBR650R Blinkers not working correctly

I got some dynamic blinkers off t*mu, and installed them on my CBR60R 2020.
At first they blinked like crazy, so i bought some resistors that were marked "for blinkers" and installed just on the two rear blinkers.

Then they blinked normal, i thought..

Now when i just turn the ignition on, they blink nicely, and it looks normal in the dash aswell. But, when i turn the bike on, and go riding, and get the rpm's up, they blink faster...

How do i fix this?? Do i need less/more resistance?

You need a new LED capable flasher relay. Honda uses a weird resistance on their LED signals and it’s hard to get it right to where it wants it. Replacing the relay fixes it once and for all.
