Bought the special 5/8 spark plug socket, got a extension and everything was going fine. Tried to get the 2nd spark plug out and it seems like the socket will not even catch the spark plug to grip it out. I looked inside nothing blocking it but the plug is at an angle to the left side and the bike is NOT on a center stand. A friend suggested i get a swivel-head socket, what do you guys think? Could it be stuck any tips for getting it un-stuck?
