loose carbs?

Unfortuately, you're wrong. MR9 is highly oxygenated and that is how it makes power. As far as using it on street bikes, it is just fine. It will cause no damage. A friend of mine, Robert Jensen, who is the current F-USA road racing champoin in both the superbike and superstock classes uses it in his bikes. They are both limited to STOCK internals. His CR is raised to somewhere around 14:1 and he uses MR9(87 octane) in both, and they hold up fine. He sees around a 10 RWHP gain with that fuel.
As far as straight race gas, what fuel are you speaking of? VP makes over 30 different fuels alone.
And engines taking a crap from race gas? That one is new to me. The only bad thing about a fuel that I've seen is how Nutec will eat through fuel lines if not purged each day.
Oh yeah, and just this spring, Arcane Racing "squeezed" 701 HP from a Hayabusa. Stock was prolly 155-160. So, there's some room to move in the HP department.

Ethan is right, and I gotta chime in here too. Fist off, high octane fuel doesn't make more power by itself, in fact since its harder to burn it may make less power. What high octane fuel does do it reduce knock. That is all the octane ratings really mean.
So, you're now probably asking why use high octane fuel if it doesn't add power? The answer is simple: It reduces knock which adds a layer of safety to an aggressive tune. For example, lets say that you can squeeze 200 whp out of a vehicle on pump gas w/ 18 psi of boost before knock, you should be able to run a bit leaner and/or turn up the boost and/or advance the timing if you run C16 which should in turn get you to a higher whp.

First of all, in a street bike you do not want to run straight race gas, you want to mix it 50/50. I have seen way to many engines take a crap because it can not hold up to that gas. GP bikes run this gas for a reason, because the engine can handle it. I still don't see someone getting 5-10 hp from the gas, do you realize how hard it is to squeeze more HP from these bikes, esecially a carburated one! If you are the average rider on the street, just run the top pump octane you can buy, otherwise you are wasting your money.Funny guy... Word of advice. Dont argue with ethan about bikes, you wont win.

what he said^^

I guess I should not try to compete with you, since you are so knowledgeable about bikes, right? Whatever. This is not a competition what so ever, I was just trying to help someone out, and you took it way out of context. He has a jetting problem, not a fuel problem. And not to mention it is a carburated CBR 600, it is not ment for a speed demon, it is ment for riding. Come on people, quit trying to prove you are so knowledgeable, and enjoy the motorcycle for what it is ment for, RIDING! O, I forgot you can only ride 3 months out of the year there! This is not a pissing contest, I was just trying to help someone out. Come out here to California and ride with me sometime, then we will have a pissing contest!

In Roller28's defense, ^ how is this not true? It was my understanding that higher octane fuel was recommended for a bike like jct's. -
But he also said that race fuel has blown up some engines that can't handle it. All Ethan and I were saying is that Race gas doesn't add HP, it adds safety.

If the bike ran fine before, then the jets are correct. It is probably in need of a cleaning and inspection.Roller28 wrote:

Not fast, eh? That bike won the AMA 600 Supersport title in '95. -

I'm on your side here Chuck, but oxygenated fuel does add HP, with no other changes to the fueling, engine timing, or forced induction. -
Why do you people have to get so F'n technical? Clean the jets or change them out, I was just trying to help this kid, and yall have to jump up my ass about this! And whether the bike won a championship 10 years ago does not matter, try runinng that bike vs a new 600! You all spend way to much time in doors during the winter time, I swear!

I then joined the Military to serve my country, and ended up here in sunny california. Would you want to move back to Fargo? I love it out here, it is nice and warm, and so much to do. I get back to Fargo every X-mas, and I realize when I am home, why I left. I hate the COLD!
