    This thread caught my eye. In the process of doing up a Sporty atm. Purchased 2nd hand you say? Couple of things to consider:
    a) Check and adjust you Handlebar Control unit [that whole part that contains your front brake lever, throttle grip and switches]. 4 bolts [2 of each different size]. By rotating this forward will allow for some wiggle room with throttle roll on. I've seen a few moved back toward the rider so they can better reach the brake lever???
    b) You mention grips, check to make sure they are genuine, [ by genuine, i mean the distance between the cable ends (notches/ferrules) are around 10mm or less] many Chinese copies the gap is wider and you end up with no adjustment within the cable.

    Below, is a pic of mine thus far, still an 883.  New bars, Just painted the engine and added a 2-1 system, still getting the tune right [running a bit lean in both pots]! Had her out on the Highway this morning, sits on a $1.10 and will skip to $1.40 very nicely!
    Cheers S

    Yep. My 883 will run at $1.40 no probs but the little sewing machine is certainly singing at that rate. Needs 6th gear.

    No, but another option is to put a larger front transmission sprocket on that helps lower the RPM at motorway speeds.

    Yep... 30 tooth up front (any larger and there are belt interference issues).  Buy a used 30 tooth online cheap and get a shop to swap it out, as that tranny nut is red locktited on and those cheap chitty alloy sockets deform under load and break.  You need a good impact wrench.
    Plus you need to reprogram your ECU as the gearing change alters the speedo reading (as this is taken from a tranny sensor).  
    Comes back to knowing if you have an aftermarket ECU or not.  If your stock Harley atm, with no other fueling changes then that is why the bike runs like chit at highway speeds.  The Sporty NEEDs more fuel with a stage 1 to get good highway speeds (some may disagree, but I have been through the entire saga so speak from experience)

    For carby models: 185 main jet is the go.

    or 220 if blown, BUT the sporty in question is a 2013 so i recon its EFI.

    Ran a 190 main in my 96 sporty sport 1200, a dyno operator decided it was too much and took it out, bike wasn't as quick off the mark, pissed me off at the time, miss that bike, was my first harley.

    Why not just find a dealer with a 1200 stage 1 and take it for a test ride?  That should answer your questions.

    I achieved much quicker throttle response/acceleration by also making a new pump rod ~1.2 mm longer.

    I reckon you know more about carburettors than me, I had a Yost power tube as well, I don't know if that's snake oil but it was my first CV and I fell for the science/hype on them, messed with the clip height untill I got it right, can't remember all of it now, was awhile ago.
