octane rating
hey guys. i got my owner's manual in the mail today(i just bought my bike). i noticed it recommends anything above 86 octane. i thought most crotch rockets needed 93, am i wrong? should i go ahead and start putting 87 or 89 in it? sorry if this question seems elementary, but it surprised me that it only needs 86 or higher. thanks in advance! oh, and it's a 600rr.

RE: octane rating
That is true..the motor doesn't require more than standard grade fuel..but most people run the higher grade just because they can and the difference is probally .80 cents per fill up. Some motors require higher octane, but obviously that one doesn't..

ok cool, i think i'll keep putting 93 in until it cools down here in FL. i figure the higher grade fuel will have a better resistance against pinging in the high heat. but once it begins to cool down i'll step down the octane. thanks a lot for your help, limpz.

RT - my dealer actually suggested that I don't put the high octane in my bike.
they said it only calls for the lower octane and will not like the lower octane if you run high octane in it too often. once in a while is alright to clean things up.

Your bike does not modify the ECU according to the fuel type/octane you use.
Rule of thumb is: If you have not rejetted your carbs, installed a full exhaust system, installed a Power Commander, or modified the air intake/exhaust in any way - It is a waste of money to purchase anything other than Regular/87 fuel.
I have to use Premium/93+ in my bike because I have modified it so much. If I am in a pinch and Premium is not available (in the sticks) then I can get by on Regular, but she does not like it. Pinging would not be an issue for me (since my timing has not been altered), just a loss of power due to incomplete combustion.

i think your "rule of thumb" may be a bit whacked. [sm=dontgetit.gif]
if the bike is supposed to run 93 octane, you should run 93 octane. same goes for cages, a lot of VW's for example.

We arent discussing cars, as this is a CBR forum. ALL CBR's only require 87 Octane. If we were discussing BMW moto's I would say Prem./93 MUST be used, as the manual dictates that. [8D]
p.s. How else would your bike know what octane you are using (by varying it) if your ECU didnt record/report it? That is what I read between the lines in your post. Since that was inaccurate, what are you infering?

Point taken Baldman. I was using the cages as an example.
I'm not sure if you are a really sarcastic person or not, as it is impossible to tell over the internet. But I just wanted to point out that most of your posts come across to me as being very in your face. I am in agreeance about adding humour to this forum, but ***** out trying to make people feel stupid is not necessary.
Cheers.

Yes, I am a very sarcastic (in a humorous way) person (in person). Most people dont get me and often get offended. Often I am blunt and to the point - that is the only way I know to be when the facts are involved in a discussion. Sorry if I offended you. I am sure many will be offended by my posts...not that I am proud of that - just the way my type POV comes across.
p.s. ALWAYS pay attention to the smileys in my posts, as I try to convey my attitude with them (since my wording isnt always PC).
