When pushing the bike at medium-high rpm the power shuts off, i get a lot of engine braking until the engine goes back around idle rpm. In the video i'm accelerating all the time, the sudden loss of power is due to the problem. This happens also in 2nd and 3rd gear, only sporadically and always when the engine is cold, but in one year i own the bike it only started happening 2 or 3 weeks ago, one or twice a week originally, now it's happening more often.
I tried changing the sparkplug without success
Thanks for the help, it sounds like nothing serious and i wouldn't want to ask a mechanic over nothing
