I am currently using 98 octane. But I am worried over a slight spark knock (pinking) sound which occures from time to time, not all the time. While 100+ octane is not sold at petrol stations near me, could I manually increase the octane by some additive maybe?
Thanks.

 

Yo, what are you running for CR.???? Unless it's above the roof ( not even near stock pistons), the "98 low oct.") ain't the problem... hows that time'n, are you overheating, water wetter, good oil... Is the ping, at high r's too???? Clean and free, Ripp'n

 

All stock, 4month old cbr600rr. Ping is at low speed about 40mph, dunno if its still there at higher speeds cause the sound of air get loud. I get it about 1 in every 5-8 rides, so its rare. no over heating, everything seems fine. However, I just dropped my bike for the 3600 mile service and told them about it. I'll see what they'll say tomorrow when I go get it. Even though, I still like to know how to add octane to fuel, I would prefer 100+ octane, if its not a pain in the a$$ doing it everyday, cause I fill my tank everyday [sm=gears.gif]

 

The reason your bike is "knocking" is because you're lugging it. The 600RR is meant to be revved dude. Especially starting off or up an incline you gotta let that baby breathe ... give it RPM's and I promise the "knock" will go away

Please don't waste any money on octane boosters -- they will not in any way help your problem.

 

If you want to boost your octain, get some VP racing fuel. Or find a Unical 76 station that has a 100 octain pump. I know in So cal we have 100octain pumps at SOME 76 stations. BUT

I ran out of fuel *dont ask how or why* lol. I just did, and my buddy brought me a coupel gallons of regular...my bike didnt ping or knock...but I did notice a huge performance loss.

So, i don't know what to tell you if the octain does not work. DONT spend the money on a 'octain' booster, they dont work for ****. VP 142 and mix it 1/2 - 1/2. My 2 cents.

 

A CBR600 does not need more than 87 octane. You will have worse performance with higher octane. STOP wasting your money!!!!!!

 

kidding me? 87? thats ridculous.. the manual says use 98, look up racing sites and other info, on track they use 100+
oh i got my bike back today, its sounds better... here petrol stations don't have higher octane fuel, cause there's no demand on it...
thanks however...

 

I was just about to say the same thing; doesn't the owner's manual "recommend" using only 87 oct? I believe it does. Now unless you've done some major engine mods I don't think you really need the extra octane points.

My $0.02.

 

Yes, there is actually les Energy in higher octane fuel. It burns slower and is a waste of money and your engines potential. Our ECU is not designed to take advantage of higher octane fuel.

Unless you have a dyno, a knock sensor and a wideband w/ egt. I seriously doubt you have the tools to take full advanteage of the higher octane rating.

If you were to raise octane thoug, id use race gas, jet fuel, or toulene/xylene.

 

oh no. did i get the wrong manual? [sm=redx.gif]
