Hmmmm did not know that. It was an authorized Honda shop but they don’t really have big bikes here.I have seen that before. If the inner liner is cut ripped or punctured the air seeps thru the cords. Make sure the bead was not ripped or cut during installation the most likely cause.
A 250 is pretty much king. People take pics of my bike EVERY TIME I venture into town cuz it’s the biggest they have ever seen
