Different gas question

[flsurfdog]

So after switching over to 87 octane (georgia if that means something different elsewhere) i had a thought.

since lower octane gas is more combustable (more prone to detination) because it's made of smaller compounds.....and higher octane gas is the opposite, however more energy released when it does burn, so (assuming the bike runs normal on low octane)  would higher octane gas give a similar effect as to making the bike more rich?  I mean the stoichometry between low octane or high octane, and air would have to be different, and if you're injecting the same volume of fuel could this not help the lean running conditions of the )₂    sensored bikes?

Personally I think my Bike runs better on lower Octane 

Thats were my knowledge ends

Air to fuel ratio is air to fuel ratio regardless of octane, so the answer is no.  Using octane of too high a rating can cause incomplete combustion and reduced power output though.

Is this why valves appear more gunked up with engines that run high octane that don't need it?? It's just left-over crap that doesn't get burned??

I've began to run 89 in my bike full-time, and it doesn't complain....In fact, I've noticed it doesn't do the airbox "sneeze" when the throttle is cracked as often as it used to....I don't know if that has anything to do w/89 versus 93, but it's a possibility!!

It is a reason why you could have excessive carbon build up.
