Forgot about the ethanol mix!
I've heard/read too many horror stories about people running an ethanol blend fuel in a vehicle not manufactured to do so. These problems usually occur after prolonged use and involve deterioration of fuel lines, seals, fuel pump components, e.t.c...
If your owners manual doesn't specifically state that your motor was designed and built to run on an ethanol blend fuel don't touch the stuff.
Thanks for confirming my suspicions on the fuel with ethanol. And I don't want the higher octane fuel because the bike doesn't burn it completely and it creates carbon built up. So the lowest available, without ethanol is 92 octane, right?
I don't understand how a higher octane fuel can leave carbon deposits???? The reason that they use higher octane fuels in the first place is because the extra octane rating makes the fuel burn better and cleaner. The only problem with higher octane is that it will run hotter (due to the more efficient burn) and can cause problems associated with that especially with air cooled engines. (hence the reason that you would not use high octane in your lawn mower or whipper snipper). But over all I do not believe there is an issue with it.
In my old Honda (K3 750/4 SOHC)I run 98 Octane and add valve lubricant and it has never missed a beat.
From other related topics...
"Octane is the rating of the fuel's ability to resist abnormal combustion due to heat or pressure. Abnormal combustion is defined as any burning that is not initiated by the spark plug. Octane has nothing to do with the fuel's ability to make power other than the fact that, properly selected, it allows the engine-builder the use of high-compression, aggressive cam timing and any other trick that elevates cylinder pressure. The power potential of gasoline is related directly to its density. Density is determined by the grade and quality of the crude petroleum, the refining process, and whatever chemical additives are included before shipment to the retailer."
"The only mods that will require higher octane fuel are: Blower, Supercharger,and High Compression >10:1. Changing the exhaust, doing BAK or anything else besides bumping up the pistons or shaving the heads will not effectively raise combustion pressures. Timing is actually adversly affected by using the incorrect octane fuel, and causes a decrease in performance and gas mileage. Do a search on octane ratings and you'll be suprised what you find. The money you save will easily go towards that next mod or a few cases of some real fine beverage, especially if gas prices keep shooting up."
Since high octane in a low compression motor will not burn completely - you will get a lot of carbon deposits (as mentioned earlier) if you run it all the time. Also, do a search on this topic. You will find lots of info to support this as I did. The bottom line is you'll get the same results from regular fuel as you would with premium, unless your bike in pinging. It would help get rid of it.
