[QUOTE="SoCalFJR1300, post: 1066766, member: 34386"] You can have slight detonation, running 85 and not hear it and over time develope engine issues. Why risk ruining your engine to save a few cents a gallon? These are motorcycles that get very good milage anyway. My .02. Every cycle/car owners manual I've ever read says 87 "minimum". (other than performance/sports cars and some cycles which call for 91) Friend of mine was running 87 in his Mercedes and his owners manual said 91 minimum.....he develpoed engine problems and the dealer tested his fuel.......they refused to honor the warranty.
