I wish we had 98 octane!  So I saw that a few of you mentioned octane booster.  What brand (type, flavor, etc) would you recommend?
Thanks

Fuel in Australia is under a different octane rating than we us in the US  they use straight Ron we use R+M  so a 98 is 93 .. sorta .. Our R+M is a odd method to come up with the rating.

OUR rating is R+M  ( RON + MON)  ( copy past stuff below) really just a glimpse of what really goes on, But it give's you  an idea of how far off the fuel can be ..  And that is not taking into account hoe the corn juice will effect the fuel.

Get used to it as it will not get better.
Research Octane Number (RON)

The most common type of octane rating worldwide is the Research Octane Number (RON). RON is determined by running the fuel in a test engine with a variable compression ratio under controlled conditions, and comparing the results with those for mixtures of iso-octane and n-heptane.

Motor Octane Number (MON)

Another type of octane rating, called Motor Octane Number (MON), is determined at 900 rpm engine speed instead of the 600 rpm for RON.[1] MON testing uses a similar test engine to that used in RON testing, but with a preheated fuel mixture, higher engine speed, and variable ignition timing to further stress the fuel's knock resistance. Depending on the composition of the fuel, the MON of a modern pump gasoline will be about 8 to 12 octane lower than the RON, but there is no direct link between RON and MON. Pump gasoline specifications typically require both a minimum RON and a minimum MON

Good info Steve.  Thanks!

Any so-called octane booster that's labeled street legal is a waste of money and doesn't increase octane enough to measure.  There are some products, like the one from Lucas, that provide a measureable increase but they are not legal.  But even with those, the increase isn't what the ads imply.

If you want to avoid problems when riding in areas that don't sell premium, the simple answer is to have your bike tuned to run properly on a lower grade fuel.  If the best you can usually find is 89 octane in the areas you ride, then be smart and have the tank full of 89 octane when you have the bike tuned, not 93.  Problem solved, and you can save 20 cents per gallon as well.

So recently I ran 89 octane in my bike due to the station being out of 93 (I know theres a post about this already).  And I was convinced it made my bike run bad.  But I had read in a number of places that I should actually be able to run 89 with no issues.  And since I recently removed my fuelpak, I have been using 89 with not one single issue.  Actually runs a little bit more aggressive with 89 over 93 (guessing its a faster burn).  I am not getting ping at all.  With the removal of the FP, the bike has a little less torque on the bottom end, but it runs smooth and consistent.   It does get a little hot.  I am installing Fullsac TD's this weekend, so I am curious what that is going to do.  But I digress what are you guys all running.  89 -93 - 100?

Good move on getting rid of FP. I hope you are using another tuning device with the addition of the fullsac TD?  If not you are asking for trouble and the bike will run too lean. Steve at Fullsac can get you set up with TTS with one of his canned maps already installed.
