I purchased my 2015 Scrambler from a reputable dealer over the winter. I just went to change the oil for the first time since (I only put about a thousand miles since). I immediately stripped the 5 mm Hex head - I think the plug was over tightened at the dealer. Any advise on how to remove the 5 mm Hex now that it is stripped? Going on a trip in a couple of days. Thinking of not bothering to try before, but still wanted to do the oil change myself like I have done in my other bikes.
