Hello, I bought my son a 2021 yfz50 in April. He rides it hard but the bike has been handling it just fine. The other day he parked it for a few minutes and when he jumped on to start it all he got was a buzzing sound from the starter relay switch. It starts just fine when I use the Kickstart. I checked all of the fuses I could find. Battery voltage is at 11.43 last I checked. The ground wire is still in place. I'm at a loss here and would appreciate any help you can offer. I searched the forums and didn't find any threads with this problem. I'll post a YouTube link below of the sound it makes. Thank you for your time!
