I'm about to go look at an 05 raptor 660r and the guy told me that he has it set up to run rich, which why he has it rich is because he said it creates more torque. Is this true>? It sounds kind of fishy to me and i've never heard of running any bike either rich or lean. halp please. it also has a 11:1 wiseco and hotcam if that has anything to do with it.
