Hi there, so i recently bought a new Semi-auto SSR 125. I have followed the "break-in" procedures that the manual says to do. But it has recently started to keep accelerating even after I let off the throttle. I try rotating the throttle all the way closed, and it works sometimes but other times I have to push in both brakes and rotate the throttle closed. I have about an hour and a half on the bike. Thank you.
