As I recall, you don't do the work on your bike. You take it to a shop. If that is the case, what do you hope to accomplish by posting the video?
IMO, you would be better off finding a really good trustworthy shop and let them figure it out. Typically, the advice provided on the forum is utilized by the person asking the question. Putting the forum members in between you and the shop only adds confusion. It erodes trust between you and the shop.
On the other hand, if you were to do the work yourself, then you would always have first-hand knowledge of exactly what has been checked, how it looked, if it was tight or loose, how it was adjusted, etc. You would also learn a lot, improve your skill set, and accumulate the necessary tools.
If I got your situation wrong, please set me straight.
The noise in your vid seems to be more predominant at the top of the engine, and you say it is on the left side. My vote is decompression release mechanism. Loosen up the cable and see if the tapping goes away.
Thank you. I do some work on my bike, but for more complex stuff I take it to a shop.
To access the decomp mechanism, is it just the tank I need to remove?
