I have a kx250f and i usually run 105 octane in it because it doesn't burn as hot as regular 93. But its a little more expensive. Me and my mom were at the store tonight and she seen this STP Octane boost. She asked my if that would make my bike faster instead of having barrels of 105 in the shed . I didn't have an answer for her. Has anyone ever used the STP Octane boost in there dirt bike before?
