slight hesitation in the 2300-3000 rpm range. been doing ever since

[flyingz06]

new.  seems a little worse depending on the gas i use.  above 3000 is silky smooth.

do i need to take it in and have them fine tune?  can they even do that?  thanks for the input!

or would a new aftermarket exhaust take care of it?

Is that hesitation just lugging? I find that "The Beast" likes to rev a bit higher than 3000 rpm to be happy.

What grade of gas have you been using?  If you have been using premium start running regular and see if 2-3 tanks cure it

My Trophy also likes revs at 3K or higher, especially in 6th gear. If I have it in 6th and the revs drop slightly below 3K, I can feel a distinctive change in the vibration through the seat when I accelerate, which reminds me to downshift. In lower gears that sensation is much less noticeable unless the revs are around 2.5K or less.

When I first took delivery, I tried various grades of gas and quickly settled on 87/regular. That's the recommendation from Triumph and also saves money. Higher octanes don't seem to make any improvement, although the engine runs OK. With 66K (miles) on the bike now, it's still running great.

when I ran premium the plugs quickly fouled as if I was running too rich..  I switched to 87 and three tanks later the bike was back to normal

My experience is mostly with the 91 ron recommended, and no running problems from fuel. I have had no need to run higher octane except the few times where E10 only was available and I needed to maximise fuel range.

I can run mine down to 2000rpm but it prefers 2500rpm or above.

Interesting problem for people outside Europe, my bike in the UK is perfect at all revs I run on what we call "regular" perhaps 1 in 10 tanks on super as that is what I do with all my vehicles. Judging by the lack of replies from "Europe" I guess it must be something about your petrol (gas)

The subject of fuel grades / Octane ratings has been discussed quite extensively here :
"Black carbon deposits around the exhaust tip." See post #11 

Be aware too that the Trophy may be tuned differently for ( some ? ) different world markets,
and that tune may take into account the fuels used in those Countries,
which may be specified differently in the Owners Handbooks for those Countries.

Uisng too high, OR too low an Octane rating than what is recommeded,
can cause engine performance problems 

It is an urban myth to use a higher Octane rated fuel than recommended,
but a lot of people do this, maybe once a month, or after a certain number of fill ups with "Regular" fuel,
thinking that they are doing their engine a favour by giving it "some of the good stuff" every now and then,
the myth being propagated by Fuel companies calling the Higher Octane rated fuels "Premium Grade" or similar 

Best advice - read the Handbook, and put fuel in the tank according to what it says in the book !
