hey a sunco station near by sells racing fuel 110 octane it a little price but every once in while would mind filling up with it would it benifit my bike

you probably won't notice any real difference........but the exhaust will smell awesome!

Be careful not to get it if it is leaded. Otherwise it shouldn't hurt at all.

 

contrary to popular belief, octane rating dosent have anything to do with the quality rating of the gas, it is a measure of the temperature at which the fuel will combust. High performance racing engines require high octane to prevent pre-combustion (ping), because the run at higher temps. This is also why the air cooled V twin require "premium" fuel. Putting a higher octane fuel in your bike than what it says in the manual is just tossing even more money to the oil companies than you already are required to. sorry.....end rant......

 

I believe 110 is going to be leaded, which will foul your O2 sensors if you have a FI bike.

 

If you have an EFI bike with O2 sensors could present some problems. If you have an EFI w/o sensors it would run, but like mentioned earlier why run 110 thru your engine when 93 will be just fine?

 

Yeah there will be very little if any benefit to running a higher octane rating than what you are tuned for. If you are pushing as much timing and compression as you can for a specific grade fuel you never want to go less due to detonation/knock, but going with the higher rating won't really help you.

 

Huh? Gasoline's octane rating is a measurement of its relative rate of burn, irrespective of temperature. The higher the octane, the slower the burn. The lower the octane, the faster the burn. Lower octane fuel can pre-ignite and burn extremely fast, which is essentially an explosion rather than a slow and controlled burn. This is what we hear as "spark knock" or "pinging."

The temperature of the combustion chamber can be a factor with fuel that has too low of an octane rating. Hot spots on the piston top, or even the heat of compression, can cause low octane fuel to pre-ignite.

One of the reasons diesel engines sound like they are pinging all the time is because they are. Diesel fuel is very low octane and combustion in a diesel engine is caused by the heat generated from the extremely high compression ratio. At near TDC, the compressed air charge reaches temps in excess of 1000 degrees, and at that point the fuel is injected, and BANG, combustion.

 

heh, this is what I get for believing what dear old dad told me 20 years ago I also found this on the net:
"The octane rating of gasoline tells you how much the fuel can be compressed before it spontaneously ignites. When gas ignites by compression rather than because of the spark from the spark plug, it causes knocking in the engine."

But my basic point is still true, it really has nothing to do with how clean, or how high a quality the gas is

 

This is not necessarily true,

knock is when combustion occurs too soon before TDC and actually attempts to force the piston in the wrong direction. For optimal power you want some ignition lead before the piston reaches TDC, but too much can be detrimental.

 

No, not at all.
