Yep the whole throttle has been checked, it still snaps back ok!
I was in the top of 3rd when it first did it and the bike just started screaming, I dont think I picked up a lot of speed but I wasnt thinking about the speed just trying to stop the bike. It then did it a second time about 4 laps later when I was going over a jump, same thing bike was screaming, hit the kill switch ran a few seconds before stopping. I am not 100% convinced it is the throttle but people who heard it said thats what it looked and sounded like.
It just ran so loud and quickly, but then would start straight away and idle and ride normally
