Today out of nowhere I feel like the bike isn't as responsive, I take off my helmet just to hear this awful ticking noise, what looks to be at first like it's a faulty CCT knowing f4i's are infamous for those going wrong, but it also feels like it's coming from the left side of the bike, couldn't it be something related to the valves?
I dont know how many milage is on the engine since I did a swap myself not so long ago, but it was running very fine and smooth before.
Oil is motul 5100 15w/50 since it gets pretty hot where I live
Here's a video showcasing the sound
Thanks in advance

 

I don't know enough to say for certain BUT I believe that valves do not make that noise. I'd be inclined to replace the CCT first, if only because it's the easier of the two to try and if it doesn't fix the issue, well, now you know it isn't the CCT!

 

Here are a couple other threads I found that might give you some other ideas...

Good luck and hope it's nothing major!

 

CCTL won't show a power difference. Valves would, but they don't just go out and cause a difference it takes a long time of gradual change.

 

I ordered a manual CCT, just to make sure, I'll try it out thanks!

 

Just went through them, sadly none of them resembled my issue, I did find an old abandoned post about an F3 that had my issue but OP didnt follow up to what was the problem, thanks a ton!

 

I wouldn't say the power difference is noticeable as much, it's just that it wasn't as "responsive" ?

 

Yeah, it can be tough to find the same noise when you aren't sure what is causing it! Sorry I wasn't much help but if you do find and fix it, please let us know!
