It's okay Tahoe SC. I didn't take it personally. I also didn't want to sound bad either. My bike says that it has 12k on it, but with the +1 sprocket on it, the mileage is off. I know for a fact that the guy who had it before me rode it kinda hard, so I tend to baby it a little. I just always put premie in it. Thanks for all the comments guys.

 

Why are so many people hesitant of doing what the manufacturer suggests? The owners manual for my wife's 05 600RR recommends lower octane gas like 86-88 and my 06 1000RR says to use only premium. There must be an excellent reason Honda went through the trouble of coming up with a sticker that they placed on tank right near the fill access door, on the 1000RR, that states use premium gas only. (I will be removing all warning sticker by the way.) Just to see what difference there might have been I've used both premium and regular grade gas in the 600RR and could not tell a difference but you can be sure since Honda went out of there way to advise me to use premium in the 1000 premium will the only gas I use in it.

 

Because it's been drilled into our heads that if it costs more it is better. And face it, we all love our 2 wheeled friends and want the best for them. The actual cost to the oil companies to make 93 over 87 is on a few cents but you wouldn't know it at the pump. And with all the talking car commercials telling how much they love the premium ....

Here's the good news. Using higher grade octane than you need won't hurt a thing. Your bike can not get "used" to it and then need it for real after that.

Tahoe brought out a great point about older engines with carbon deposits running hotter. The little carbon kling-ons will predetonate your fuel charge. There's an easy way to diminish these deposits. Involves squirting water into the throttle bodies while the engine is running. Fortunately fuel injection has helped a lot with keeping the pistons and valves free from crud.

Because they run higher compression than your bike. Octane rating is basically a number that tells you the fuels resistance to detonation. [/quote]

Ding ding ding, we have a winner..I havent been here long enough to hear the other threads about this stuff nor am i gonna go read them. However i do know that octane is just the fuels capability to resist knock/detonation for higher compression engines.

 

bump.. lower the elevation more air pressure there is meaning you need better gas, depending on compression of course.. also a big bump on the pinging, if your car/bike pings then you need better gas. simple as that.

would be currious to see the diffrence of 87 octane vs. 120 octane on a dyno though.

 

The higher octane gas just needs a hotter spark to burn properly.

 

Negative Ghost Rider.....

It needs higher compression....

 

WHOA, WHOA, WHOA!!!![sm=badidea.gif]..........

Be careful how you say this, the next thing we'll have is another post with some one taking your advise and Hydraulicking their engine.

Maybe be a little more specific. However, I can honestly say I have never heard of this nor do I suggest it.

 

Y'all need to understand something. The octane values have nothing to do with quality of the fuel. So quit saying low grade and high grade as this does not have anything to do with quality.

 

We're talking 5cc's of water slowly injected into the air stream while maintaining a constant throttle above 3500rpms. This will get rid of the majority of carbon deposits on your exhaust valves and pistons. If you were running a forced air system you can use a water injection system to cool the charge instead of an intercooler. You'll absolutely have the cleanest pistons and valves you ever saw -- just a byproduct of the water being injected. It's perfectly safe as long as you don't get stoopid with the amount of water. It only takes a little.

As far as altitude and octane or bigger sparks ... octane is just a number assigned to gas that indicates what it's resistance to detonation is. Period.
