How much difference is there between the standard 11/31 ratio and the 13/28 ratio? My son drag races a 500ft dirt track & 1/8th asphalt. Would a 13/28 hurt or help with this type of racing? And would it change the launch of the bike? Currently running 19t and 28t sprokets and snow hog tires, would a taller tire help?
