What grade of fuel does the K require?
Book says 89, but a lot of guys run 87 or whatever is at the pump. So far I have only put in 89, but up in Canada at some of the remote stations; I'm sure I will (have to) do the 87.What grade of fuel does the K require?
No it's not...With 87, the bike will run just fine. The knock sensor will prevent the bike from making full power, just like in most high compression modern cars. The bike can't reach full potential until 89 or better is used.That's a change from BMWs of past, then. Thanks for the update.
Well according to the experts here at FJRforum, High(er) Octane doesn't give any more power than the lower grade fuel. We had this run around back awhile ago and the thread went on and on........No it's not...With 87, the bike will run just fine.

So maybe they should rank bikes according to the fastest ST using regular fuel. Of course, that would be stupid too.
At least I got a chuckle outta this! I'm sure if the Feej took 1st, it would of been all banners and balloons here, lolWell, if you are spending more money on the high octane fuel, the bike has to be faster. The more money you spend on fuel, the less weight in money you are carrying. Less weight equals more speed.
Yes, that sounds dumb. But not any more dumb than the article this thread was based on.
Roger That!IIRC about the octane thread, what was said that anything higher than the motor was designed/tuned for is wasting money. With the FJR, it was tuned for regular unleaded. My comment about the BMWs was based on those I know from friends which were tuned for premium unleaded. They would run without damage at lower octane because of the knock sensors but they did it by retarding timing (?) so weren't optimal.
But that's just my understanding off the top of my head.
Just keep riding, the connie only has a 350km range (on a good day) you will pass them in he gas stationHad my lunch handed to me one day by a really fast guy on a piped Connie 14. I hung with him for a while on a great stretch of road and lost my nerve--say what you will--those things are simply fast as hell.
Have ridden many a spirited ride with ST1300's and been very evenly matched until they left me in the gas station. But that was on my 650 Transalp but now that I have an FJR things may change...Havent' found an ST yet I didn't eventually go around. Same for any twin Beemer.
Trent, your GTL is speed limited (compared to the GT), but glad to know it can keep up w the Feejer.I have had my new BMW next to my 2006 FJR wide open and they were very very close at the limit. I think the BMW might have took it by a nose.
+1, Gunny; I run 89 in my K1600GT, but it has run just fine on 87 here in Estados Unidos; down in Mexico it prefers PEMEX Premio but it also runs just fine on Sin Magna ese; up in Canuckistan I run either 87 or 89 octane, but with every fill up I add six ounces of Forty Creek Whiskey that I steal from yamafitter - Billy Fitz! jes' sayin' and nuff said, eh!Roger That!IIRC about the octane thread, what was said that anything higher than the motor was designed/tuned for is wasting money.

I think BMW has finally come to reason that HiOct fuel is not all that desirable to owners, especially in this economy right now.
Don't read anything here then... It's Fecking worse!I want that two minutes of my life back from reading that 'ranking' article.
