Hello. This scenario have happened several time already. After a few hours of riding bike suddenly stalls, then won't start. New plug doesn't help. After some time, around 10 minutes, bike will start fine. Then sometimes it will ride fine, sometimes will stall again after short time. Below is a video of one of the incidents. I own this bike from October and this is my first 2t. This only happened in weather with temperatures below freezing and snow on the ground. Bike is jetted for this weather according to the book, but I have fresco pipe, not the stock one, so this may affect jetting I suppose. In the fall book jetting worked fine. Also this always happens after riding some time in 3rd gear or higher and in mid to high rpm. I always fully warm bike up before riding. What do you guys think? Is this jetting issue or carb icing? Thanks.
