I'm new to this so bear with me. I have a 2 stroke kit on one of my mountain bikes and when I first set it up I did not know the threads on the front mounts were removable and I had to use the universal adapter thing so I let the threads sit on the front bar. eventually they shaped off and left stubs. that's when I found out you needed to use the bolts that came with it and take out the threads.I put on one bolt without the washers thinking it would tighten all the way down. I was using a socket wrench and did not realize that it wasn't screwing down anymore and the bolt snapped. the thread is still stuck in it and I don't know how to get it out. none of it is putriding so I can't use pliers. any help would be appreciated.
