2020 M8 cold start knock

Hi all,

I have a new to me 2020 Ultra FLHTK with 7k kilometres with a bad cold start knock. Sounds more (to me) than a lifter. Please correct me if I'm wrong. Has anyone encountered this? Going into the dealership after New Year, just asking for any experiences. Thank you. I'll try and up load a video
have tried to upload the video but I'm not tech savvy enough
* Update the upload may have worked

Always best to post video to YouTube and then link YouTube URL… In todays malware ridden society, I for one will never open an attached file from a web forum, especially from someone’s first post.

Pull the plugs, pop open the pushrod tubes check for a collapsed lifter. You can rotate the engine with the starter or lift the rear wheel drop into a gear and turn the tire. I would do that no matter what so the dealer can’t bs you.
