So just got reading a few thing and am stumped... ethonol in the fuel make your rubber goodies rot out, kills the gas milage by 10/25% Premium used to be 97 oct and now is concidered to be "racing gas", i thought that was 100 oct plus depending, here's the million dollar question: Using volume of 4.6 gl for right now is E10 and 90% pure gas at 91 oct(comon for premium)and lets say a product stating oct booster treats the standard 16 gal car tank / doesnt state what oct it raises your fuel too. Could it be all our bikes run lean because of crap fuel? btw i suck at spelling  | ||
| Froggy |
No. They run lean in stock trim because it needs to meet EPA requirements. | ||

You can still get91/93/97 at some stations, just most places stopped selling 97 "Super Premium" when gas prices started climbing. If they can call it "Race Gas" now and sell it, they will. It's just marketing. All our cars run lean because they have to, to make the exhaust gasses hot enough at idle to make the catylitic converters hot enough to do what it is they do, in order to pass Federal/Euro emissions standards. The ethanol just adds to the problem, as well as running up food costs by taking vast amounts of corn from the food supply. Until the current administration stops working toward "necessarily higher energy prices" to push green initiatives, and multi billion dollar agri corps like ADM stop giving massive kickbacks to Congressmen to keep the corn flowing to the oil refineries...... Geez you've really got me on the soapbox tonight!  | ||

wooo hooo preach it brother lol. so the question remains with e10 91 oct gas how much oct booster to be equal to 97 gas? and secondly if i where to say trick the intake sensor by way of a resistor would i get a "oh hell lack of vocab sux" richer running on the bike? | ||

If the bike runs fine on 91 octane like it's supposed to, trying to make it run better by boosting octane to 97 will do absolutely nothing unless the engine is modified to take full advantage of the knock free ability of 97. I thought everybody knew that - if not, then talk to your local drag racer/hot rodder/superbike road racer/speed freak/tuner addict and see how much it costs to raise compression, flow heads, experiment with hot cams, etc. | ||

ijust live where 110 to 120 temps are normal with the added heat... im just thinking it cant hurt. | ||
| Froggy |
Depends on the booster. Also, using booster is not recommended, if it contains lead (many do), it can damage the O2 sensors.
Not really, the IAT is fairly low on the totem pole of things the ECM will use to adjust fuel mixture. The best and easiest way to enrichen the mixture is to just buy the Race ECM, or get a ECM cable from American Sport Bike and tune it yourself. | ||

While your spelling and grammar don't need to be perfect to post here, what you post is a reflection of yourself and if your posts are illegible, people are going to think you are illiterate. What I recommend doing is typing up your post in Word or a similar word processing application, then copy pasting it here. That way you can quickly and easily do a spellcheck and correct the more common mistakes, making it easier for people to understand what you are asking. If people can't read your post, they are less likely to respond. If you don't have Word, Google Documents is free and online and can do the trick too. That said, there have been posters in the past that posted significantly less legible things than yours, so don't feel bad. | ||

Ethanol is actually rather common in race gas. It makes up 9% of Sunoco 100, for example. Ethanol is an effective octane booster... the E85 guys are reporting using outrageous amount of boost with no detonation issues. http://www.racegas.com/fuel/compare | ||

Stevenfyre, Your questions about ethanol are good. Nice to see someone thinking about the detrimental effects ethanol has on our riding. Sir_wadsalot (I'm still trying to figure out that screen name---must be a Civil War buff) has a good answer too. There are so many negative things that ethanol is doing, not to mention it takes about 100 gallons of water to produce one gallon of E! And, as always, the politicians that are trading favors while our country crumbles, get driven around in limos. Froggy has been a bit touchy lately. Nuff said there. And as Jdugger has stated, E is used in race fuel. There is a slight problem with the comparison. Us street bikers typically don't tear our engines down after several rides to fix them! I've got a brother that has a built HD Dyna Wide Glide. Even though he filled up with 93 octane, he still wasn't satisfied. We ran all over town one day (he lives in WA state) looking for a particular brand that seals properly after opened. Even looked for it in W. Dubuque at the HD store. Most HD shops sell octane booster, so I'm assuming they make $$ doing so. Get the race ECM from EBR and you'll be happy. Only thing you may not like is you'll have less decel engine braking using one. (Message edited by two_seasons on July 03, 2013) | ||

> Us street bikers typically don't tear our engines down after several rides to fix them! Road racers don't, either! Well, at least at the club level. I do a valve check around once a season, and after two full seasons, I think I'm going to need new cam chain guides and to take things apart for inspection this year. A typical season is something like 50 hours on the motor. | ||

> Most HD shops sell octane booster, so I'm assuming they make $$ doing so. And this is at least modestly predatory and certainly misleading behavior. Most HD motors are low-compression, high-reliability, rather simple motors designed for long, smooth cruising at low demands. In this case, not only is Octane booster ineffective, it will actually reduce fuel economy, and perhaps even performance. Always use the lowest octane fuel available your motor operates correctly on for best fuel economy and performance. | ||

Does my 2009 California 1125 have a catalytic converter in the muffler? On octane. I've been using 89 oct for several years now and the motor is happy. This in coastal central California where temps rarely exceed 85F. | ||

Feed this beast the highest octane you can get at the pump. Idle advance is 18-23 degrees and it goes up to 60 something... Z | ||

Just find ethanol free gas in your area http://pure-gas.org/ it does make a difference. | ||
| Stevenfrye |
AK funny you should mention that web site I found it snooping around the net after a friend of fuel line kept degrading and failing. I just live to far away from one of the seven stations in cali | ||
| Sir_wadsalot |
There's a place in southern VA I drive that advertises it. How is that possible? I thought it was federally mandated. | ||
| Ak_addict |
To bad you live to far away, I'm lucky I live a mile from one. | ||
| Stevenfrye |
I think the federal mandate only covers vehicals that have to pass emissions. Correct me if I'm wrong. | ||
| Zac4mac |
Pretty sure the engine needs at least 91-93 US octane. It Is a rather "high toned bitch". As I said, the OEM advance map is full of extreme numbers. Funny thing is, the race ECM has overall lower advance curves than the OEM. It might get higher advance numbers up top tho, I can't remember. Steven - no, all have to pass Federal regs, some have to pass more stringent state regs(Kalifornia) If you feel the need for higher octane find a Sunoco distributor and buy race gas. ALL the other options suck ass. Z <edit> another option is a small city/township airport, 100LL is higher lead than the old Sunoco/Amoco 101 premium from the 70s (Message edited by zac4mac on July 08, 2013) | ||

i have many around me but they only sell 90 REC fuel... | ||
| Oldog |
some of our local stations are selling a 93 no lead ( at a premium price [ $3.75 gal, reg is say $3.35] ) can't tell a difference... | ||
| Stevenfrye |
Thanks old dog in response does anyone know what contain boosters don't contain lead, and if not what's the chemical name for it when I'm checking things out at the parts store. | ||
| Oldog |
One name for the lead used in gasoline was Tetraethyllead, the additive should be marked 02 safe... https://en.wikipedia.org/wiki/Tetraethyllead (Message edited by oldog on July 12, 2013) |
