I want to say hello to everyone as this is my first post. Their is a store not far from my house that has leaded gas, but it is only 87 octane. I have been putting it in my scout but sometimes my bike will jerk when you let off on the throttle. I was wondering if I should used the top grade of unleaded gas, 91+? Several people has told me that leaded gas was the way to go. My bike is a 2019 and I have had it about three weeks.
