Very common...happened to me last month. They are cheap from big dog. Like 5 bucks. I was able to get mine out but had to remove the primary. You can try to beat a torx or a metric allan wrench in the hole. I had to use a ez out.(Not really but similar)
I HATE it when something so easy fucks up,and then you have to wait for a cheap part when you should have been done and riding,i agree get an extra:angry: :angry:
Same thing here, couldn't find a replacement so Big Dog will probably be your answer. I used a metric allen wrench and drove it in. Now mine is metric plug. Glad I saw this post I need to get a couple of spares since I had forgotten.
