I just bought a 2008 V Star 1100 custom silverado, and the spark plug tool doesn't fit the spark plug, anyone know off hand what size socket the plug is. Thanks for your help.

LOL it's one of the two standard sizes 5/8 and 13/16 but I can't for the life of me remember which.

Sugar Bear's got it. 13/16 inch is correct. NGK spark plug BPR7ES is standard. With NGK plugs the first letter "B", in this case, represents the hex socket size which is 13/16 inch. "D"= 18mm and "C"= 5/8 inch. Furthermore, if you're interested, the "P" represents the "projected" tip, the "R" stands for "resistor" type, the "7" represents the heat range, the "E" represents the thread length and the "S" (standard type) represents the electrode type and/or ground strap material.
