TC 103 noise after hot
Hi, I have a strange problem with my 2017 Fat Boy, Twin Cam 103 engine.
After it is very hot, a strange noise starts, as if something is scraping around the cam plate. I can't identify where the noise is coming from.
When driving and cooling, the noise stops, but when stopping at a traffic light, for example, after a certain time (1 or 2 minutes) the noise returns.
The engine has 20 thousand miles, maintenance and oil changes are up to date, currently using Motul 5100.
I attached 2 videos: one of them with the noise and the other after 5 minutes with the engine off.
Note: in none of the videos did the engine activate the EITMS.
In the "hot" video, I understand that the noise is normal. The noise appears on "very hot" video.

I'm sure that you know the 15 number is for cold starting, right? The number 50 is what counts for "hot" operation. Changing oil won't do anything imo. Now if you say a 60wt as a test then I would agree with ya.
