    Isn't there a 140 something kit that would do your mate?
    What speeds would you anticipate from an upgrade as such?

    Wouldnt expect much of a speed increase just hp and tq to 130-140hp with a better tq curve.
    I'm sure they make bigger kits and se has 131 kits that may filter down to the softail sooner or later. 

    Yea I'm sure this question is backed Alot but searching on here I couldnt find much. 

    Why the 128 cause from my basic research it seems to be the best bang for buck. Basic research says with supporting mods ill be at 7.5k-10k

    But that's extremely rough and dont feel like asking 1000 shops as everyone will say there system is the best.

    Well more HP = more speed , more Torque = more Thrust. or Torque = Quicker HP = Faster. so you will get more speed.

    So for that money its also an option to install a Turbo or Procharger.  WAY more HP than a big bore kit and the engine is not under the constant strain they place on everything.  
    EVERY man and his dog has a big bore kit...so think 'different'

    True certinally will accelerate a hell lot better,  a reflash to raise rpm limit will help. Top speed isnt my thing instast acceleration is what I'm looking for.
    Comming from a older 1200 sportster it's what I'm missing. 

    My look at other power adders. 

    I was looking at the alpha performance engines stump puller package. 

    Just doing my research as I rather pay once xry once than going a small screaming Eagle stage 4 kit than 6 months later going bigger.

    That rough budget includes pipes/tuner but certinally a thought a stock 114 could also easily be resold I guess

    131 ft/lbs of torque and 121 horsepower at the rear wheel.
    That's with slip ons. A good pipe and tuner should see that bump up a bit. 

    Seems like a winner might lay low see what people's thoughts of them are first

    Why don't you just buy a Hyabusa. They accelerate really well. Or a Rocket 3. Just teasing.

    If you’re looking for a bike, find one that’s already done. For one you might be able to test ride it. I’ve tried a 128, guess it depends on the cam but it was horrid, reckon my old 110 with the 255 cam was quicker only because by the time the 128 got on the cam it was way past speeding ticket and it felt sluggish off the throttle. Also guys spend 40 or 50 grand on bikes that sell for 30 and less. A bit rare but it happens, especially in the current buyers market.
    Why spend say 25 on a bike then 15 getting it sorted to have a bike worth 30.

    Do not underestimate just how little you will get for the old parts... it will be bugger all.

    Good points...  I wonder how a worked 1200 Sporty vs. the 128 would go.
    The better power / weight ratio of the sporty would make a big difference + keeping the rear tyre hooked up is going to be a limiting factor.

    A sporty is great for what it is but now looking at going bigger. 
    I've been very disappointed with it since day dot. Also had a vulcan s 650 derestricted with pipes/air cleaner and it smashes the sporty. Which I think would be the best lams cruiser arround. Then soon as possible got the 1200. 
    Just over the feeling of cruising with the boys on the baby harley.

    Yea I'm quite aware you will never get your money back and seen 1000 show grade harley asking half of what they paid. I'll try to get on a similar worked bike before dropping that kind of $$$.

    If it was me I would spend the money on another bike instead.
    But thats just me; I'm not loaded like the million dollar bogan so cannot afford to throw money at a bike and then turn around and bugger it because the actual bike has no inherant value to me.  I'm pretty much the opposite, and happy like that.

    When I wanted FAST... I put a turbo on the bike and she just smoked it - no half measures with a turbo!.  Then removed it when I wanted to cruise (well actually I blew it up by pushing it to 20lbs...lol, but thats another story).

    tussuck I've been riding Harley's since late 1970's, have had some quick ones ( tested at the track ) still have not blown one up & done a lot of K's on my first one ( big bore & longer stroke ) & sold it to a mate after riding it a heap of k's for a heap of years.that was long before pro charger. only turbo's I've had was on Diesel's, so can't say much never tried one on a HD, so can't say. but I can tell you, a Hi Performance big bore HD will out last most riders if built right. you have your turbo on an EVO with the tappered crank pin?

    Blew up the turbo not the Evo.  Yep tapered everything.
