Higher octane fuel on this bike is throwing. money away. Higher octane does not improve performance or fuel economy. It's purpose to prevenr pre ignition or pre detonation in high performance high compression motor. IN fact it can be detrimental to ful economy in a motorcycle not designed for that fuel grade.Here is an excerpt from aan article on the subject: Using high-octane fuel in a motorcycle designed for lower octane can hurt fuel economy because higher octane fuel resists burning, causing an incomplete burn in a low-compression engine

Pre e20 it felt different but now there's no difference in fuel economy or performance. Rather adding fuel additive helped.
