Bought a nice new Rizoma gas cap after I installed it I decided to take it off because I wanted to check the direction of the push gas cap. Big mistake one of the bolts snapped off inside of the gas tank. So I bought a screw extractor to remove it and it snapped off inside of the bolt. FML anybody got any suggestions? I took the gas tank to a machine shop but they told me they couldn't help me because of the location of the hole.
