Re: Grade Type of Gas
running any higher octane then your bike is designed for, just makes you LOSE power, and spend more money!
F4i's I know are designed to take 86 octane.. So I put in 87 from the pump.
Although there are bikes that require 89, and some require 91..
REMEMBER, RUNNING HIGHER OCTANE THEN WHAT IS REQUIRED, DOES NOTHING EXCEPT MAKE YOU LOSE POWER, AND SPEND MORE MONEY!
I always laugh at people around here that put 92 in their f4i's, and tell me how much more power it produces
edit: I'd like to tune my bike to run on E85 just to be different lol..
After riding in my friends eclipse pushing 24psi on E85, it just seemed so sweet to fill up for $1 less a gallon!

Sorry bud, you are not completely correct. I agree that everything is designed for a certain type of fuel, but putting in race fuel in a bike like mine DOES make a difference and I DO NOT lose power.

The compression ratio on a 600RR (04) is 12:1, that is more than enough compression to run a "race fuel" with higher octane b/c my bike will be able to adjust the timing curve to compensate for pre-detonation, as well as increase engine efficiency across a higher RPM range. It is recommended you use "race fuel" when the compression ratio is greater than 11:1 and if you are running at a consistent 6000+ RPM's. I don't know about you, but even when I'm cruising on my street bike I'm still around 5k on the tach, and I don't ride my street bike like a sally... I get after it, OFTEN! Let me also remind you, when you pay for race fuel... it's not all about the compression and octane, you are getting top of the line fuel so there is less of a chance to get sediment and other deposits. Also, higher octane burns hotter which adversely can lead to fouled plugs but can also burn off deposits on your valves.
You're a smart guy, but you are completely wrong when you say "You will LOSE power". There is a reason why drag cars, race bikes, stock cars, etc use race fuel... they DON'T LOSE POWER from it. If you don't tune your application properly, or put race fuel into a vehicle that does not meet the criteria needed for race fuel then YES, you WILL LOSE power.

On a side note I didn't know that 600RR's had knock sensors.

Re: Grade Type of Gas
Higher compression "race" head??
What "race" head is this? lol
If its a TB kit, just run 87, you'll be gravy! lol
If its that takegawaya **** or somthing, then IDK what to run
edit: I've been wanting to have my friend tune my car to run on E-85 lol.. But he lives 150 miles away, so I gotta wait tell I drive to see him for that
He runs his Eclipse GST with 24psi on E-85, its sick watching him fill up for $3 a gallon then go spool up 400+hp on the 105 octane ethanol

Re: Grade Type of Gas
Yes you must burn more fuel, I believe around 20% more.. But the fuel is around 30% cheaper.. So you still save money..
Not to mention, its around 105 octane, so its great for high boost vehicles..
105 octane 'face fuel' for 5-10% cheaper then 87 octane in the long run

Re: Grade Type of Gas
When I buoght my 07 zx6 there was a big sticker on it that said only use premium gas, otherwise catastrophic engine damage may occur.
I always put premium in mine.

Re: Grade Type of Gas
i read somewhere earlier that premium has a more controlled burn and regular gas has a more uncontrolled burn. that is absolutely correct and this is why ya need to run high octane to get rid of knock or ping in the high compression ratio engines. it's all about the octane rating and it's ability to resisit knock or ping. if you got predetonation...that's bad, change your fuel quality or use a octane enhancer

Re: Grade Type of Gas
PC's just work out better fuel air ratios regardless of fuel consumption...it's about increase in power not mileage! so fill it up if you got one, my buddy does and it's a guzzler....if ur bike is FI ride then knock sensors will retard your ignition timing 3degrees for every signal the sensor produces. (peiziolectric sensor, ie-creates a voltage when disturbed by knock/pre-detonation) so if you run cheap gas, and it knocks or pings, ur loosing power cause the ECU will cut ur ignition back until the knock/ping is gone....do the math...use high test and get the most out of ur ride...

Re: Grade Type of Gas
however i thought i saw a sticker in the tail section that said 91 oct recommended but i could be wrong
this weekend running mine and the ladies bike like 1500 km. guess what ill be using.
good info guys.....

Re: Grade Type of Gas
[quote=______;3338360]I was never told what to put in my bikes but always went with sunoco 94 or 93.... few months ago I saw the truck fill the station so I asked him whats going in... he said high test... so I filled up with 89
******* rights dude...never fill after the truck is or just was filling the in-ground tanks...all the silt and sediment gets stirred up and ends up in your engine..sticky-icky...
also pretty soon bike manufacturers will be dictating you put nothing but the highest octane in ur tank....the RangeRovers are the same, put in the cheap stuff and you get engine lights on and missfires! it sucks. you want your baby running it's best right?

Re: Grade Type of Gas
i read this thread right before a long road trip last weekend and decided to give the 87 a try. i thought there is no way it will be the same. but i didnt notice a difference at all. i wouldnt say it pulls better or worse (havent tried the lot with it yet tho) but the extra dollars in the wallet makes me feel better.
however i thought i saw a sticker in the tail section that said 91 oct recommended but i could be wrong
this weekend running mine and the ladies bike like 1500 km. guess what ill be using.

I know I've seen many bikes, that say "91 min octane" right on the tank, or tail..
But I know on f4i's specifically, honda says 86 octane :YEAH
But I believe 600rr's, call for 91.. And if you run less, it retards the timing

Re: Grade Type of Gas
I have a mazda RX-7 I dont know what the octane lvl is rated for but when i put premium instead of reg. i can feel the power diffrence expecally when i put premium in and it will put itself sideways goin into second.

Re: Grade Type of Gas
Running a higher octane then what your motor is designed for, will make your stuff run cooler, but also reduce power..
