I always runs 92 or whatever the highest is they have.....I don't think of the gas cost with my bike like I do the car. Every mile I ride on the bike is because I want to....with the car it's often because I have to

$3.80??? Really man?? So. Cal. is $4.30 for 87 octane!! I run 91 in the bikes which is about $4.60 a gallon here!! Consider yourself lucky on your pricing and don't waver on the octane rating....stick with 91+ on your bike. It will love you forever!! 
Having a 4x4 with a 30 gallon tank sucks *** here in So. Cal.!!! I'm just sayin!!

If your manual says hi octane use hi octane ( year/model?)
otherwise low octane fuel may detonate/ping, and the ecm will retard the timing to avoid that.
and power and economy are lost.

Here in AR we have 93, and that is what I run. In the west of the state they have 91 so that is what I run when in the hills.
I always run the highest I can find. Like it was mentioned. I don't think of it much in my bike because I get over 40 mpg. Now in my truck, that is another story.

Always run super in my tank. The way I figure it, most stations in my area are at $3.79 for regular and $3.99 for super right now. I normally put in 4 - 4.5 gallons when I stop to fill up, so we're talking about saving 90 cents at most. Not worth the consequences of the lower octane fuel to save just under a buck.

I ran 87 octane in my bike most of the time when it was stock and also when I put Andrews 21 cams in it.
I couldn't tell any difference in power and gas millage was the same.
Try running 89 in it for a while. If your bike doesn't complain, you can try 87 octane in it and see if it likes that.
I know for a fact that some gas stations put 87 gas in their premium tanks sometimes. Your bike might already have had cheep gas in it and you didn't know it.
