I always use 87/89 whichever is the base at the station. I get 50 mpg or more out of all my bikes.
Three are TC96's, one 103 and a 110. No pinging for several reason's.
All have oil coolers, all run 12.8 to 1 AFR which provides the coolest incoming charge and the more complete burn during combustion. Most important I do not lug the motors and the receive periodic carbon removal.
The higher the octane the less burn in the combustion cycle thus more deposits. Those that add octane booster will ultimately have more pinging due to the build up of deposits from the booster which then heat and pre ignite the incoming charge causing the very problem they think that they are solving.
The 91/93 octane is $.030 more where I live. I put 30K a year on the bikes and that makes 600 gallons X $.30 = $180. It is not about the savings it is about not being wasteful. I am glad that so many have so much that they can just throw it away.

I was in the Sierra foothills a couple of weeks ago. As I passed a sign indicating the elevation to be 4000 feet my bike (See my signature.) was pinging, sounded like a bag of marbles, and had little power. When I got down to lower elevations everything was as normal. My bike is stock, I always run 91. As I was that day.

SO are these rides stock? what tuner are you using to achieve 12.8 AFR?

So the question I have is, if I have a done a stage 1, will the tune of the ECM help or hurt me in the ability to run 87 octane? I did try 87 last summer for one tank and the bike pinged like hell in 6th gear. Fuel Moto did my map for my Power Vision.
