Hey guys this happened recently, anyone know what it could be? I have a 2006 Yamaha FZ6, a friend and I swapped bikes for 30 minutes and when he was riding my bike he was revving the piss out of it in neutral to the point where it kept stalling out. Proceeds to ask me “why does it keep stalling out” told him I didn’t know but to stop doing it if it keeps stalling like that… I don’t know how many times he did it because now when i’m take off from a stop in first gear the bike boggles real bad. I used to just give it a little gas and feather the clutch no problem, now if I do that it feels like it’s going to stall unless I give it way more throttle than I used to. #motorcycles source
