Octane Booster for the injected 990 ?

I was looking thru the manual of my bike and noticed KTM wants a RON of 95 min. without pulling the wire in this bike !
I have always ran Premium in my bike's and have not been able to find 94oct in some time 93 is as good as it gets . I also use lucas quite regular .

My concern is when warm weather FINALLY gets here if I will have spark knock issues ?
I have started looking into octane boosters but not having much luck with a ounce to gallon ratio......

Has anyone had gas issues or spark knock in warm weather ???????

Thanks for your input !

Last summer I was 100 miles from a regular fuel station in Northern Nevada. Filled up with regular low octane at a mom and pops store and the stock 990 2008 Adv never even cared. Did high mountain trails and high speed gravel roads. So tried it again and same. At least my bike will run on low octane.

In town I still use best premium that I can find.

Short answer: In North America use 90 or better and you'll be fine.

Long answer: I actually talked to someone at KTM USA headquarters in Ohio about this. He said that the octane rating in the manual is the European RON (Research Octane Number) rating, which is numbered 4 to 5 points higher than the octane rating the US and Canada uses, which is AKI (Anti Knock Index). So, the 95 RON that KTM recommends in their manual is actually 90 or 91 AKI here in North America. In the US, Canada, or Mexico fill up with 90 or higher and you will be fine!

PS, AKI (Anti Knock Index) is sometimes called PON (Pump Octane Number). However, they are both the same rating.

Fuel quality questions

I travel on my 09' 990R here in Cambodia and over the years developed a system for testing fuel before it goes in my tank. I Some look at the RON number posted on your fuel pump. I have the WIB system. (will it burn)

1. What color is the fuel? red, yellow, or green? Preference is yellow, then green, red only if I am close to walking.

2. Does it reach my bike filler neck from a 2 litre pop bottle, 20 litre plastic jug, 50 gallon drum with a crank on top, or underground tanks with pump?

3. How long has the fuel been sitting in what ever is containing it? Stale, dirty, or H2O contaminated? Extended exposure to tropical sun in a bottle or translucent jug seems to degrade fuel quality.


I wet my finger with fuel, preferring my middle bird finger because it is longer and provides a more generous sample. I hold my finger in the air and begin counting seconds. If the fuel evaporates and my finger dries in 4 seconds or less, my bike will run fine. 4 to 8 seconds and I will expect burps and farts, but will roll until a better source is found. Over 8 seconds and I must decide how bad I want to push my bike instead. 10 second fuel will gum up and overheat my motor, and require a thorough cleaning of the system. Last resort fuel for sure! Likely cut/mixed with diesel or kerosine for extra profit.

Thank you !
Very much appreciated .
I was actually thinking about calling KTM this week . I knew euro fuel was different but had no Idea to what extent ...
.......
In my line of work I have seen some issue with people using the wrong fuel Gas or diesel . I'm not sure how this happens but it does quite often .
I'm sure it doesn't take much of a mix to mess with an engine either way ..........
Amazing what people will do for a profit
........
I have a feeling that there are some crazy fuel stories out there !

If premium fuel isn't available and you question the quality of the regular grade fuel you can always disconnect brown wire located under the seat, which retards the timing just for this purpose.

You're fine with 93- to 91. Owners manual calls for Octane of 95 RON, but that is a European Octane Rating and is not used in North America. We use (R+M)/2 which is the average of RON & MON.

RON = research octane number
MON = motor octane number
PON = pump octane number, AKI = anti-knock index
(R+M)/2 = average of RON and MON, i.e. (RON + MON) div 2.

Pure 93 (R+M)/2 is nearly same as 95 RON.

Let me bore you...all you could ever want to know about gasoline....
http://en.wikipedia.org/wiki/Octane_rating
http://www.repairfaq.org/filipg/AUTO/F_Gasoline3.html

When we venture out west finding anything over 90 or 91 can be difficult. Passing through the reservations in SD, best we could find on one town was 87. I carry a couple of bottles Maxima Hi-Test Octane booster for those occasions. I have found their formula to work very well requiring only small doses.

I ran into only 87 traveling across North central Kansas. Unplugged the wire and fuel mileage dropped. I think next time I travel, I'll bring along a couple bottles of booster...

when i did my trip this summer i knew i was gonna hit at least one station that would not have the best gas. i brought along a small bottle of octane boost and added it when i hit that station. i had no problems what so ever, bike didn't even know the diff.

laters,

Wow !

Lit this thread rite up .

Yes I'm not worried any more I was just making a comment about the ethanol fuel is all . Now they are wanting to raise the percentage added .... Its all a bunch of crap O la !

I always buy premium and add Lucas regularly just like getting the non ethanol fuel when I get by that way it just kills me how my mileage increases when I use it !

Ethanol is all part of big oils plan to rape the customer.. They get it for cheap because of federal subsidies but charge us as if it was not supported.

The more ethanol they add the richer your mixture has to be..

They are trying to kill the older cars to promote sales of new ones, average customer is too ignorant to protest..
