Zipper’s Muscle 110” Kit For 2008-2014 Harley Touring Models.

zippers110engineThis is for the owners of Screamin’ Eagle® CVO bikes or customers with a factory 110” Stage I kit. The 110” engine really comes alive with this top end and cam kit. Torque and horsepower is increased across the RPM range. Where the stock engine starts to level out at just over 4,500 RPM, the Muscle 110” kit kicks into overdrive and raises horsepower by 45%! Peak horsepower climbs from the mid-80’s to the high-120’s with torque over 100 ft/lbs from 2,500 through 6,500 RPM, breaking the 120 ft/lb barrier along the way. Power builds smoothly and effortlessly, without sacrificing low end torque adding needed Muscle to the Bird!

Your 110 heads are carefully ported to increase velocity and are assembled with Zipper’s Step-Lock guides, flow-enhancing valves and performance springs. After truing the cylinder head gasket surfaces, compression is raised by precisely fitting their proprietary 10.5:1 forged pistons to your 110 cylinders using torques plates. Red Shift cams, Pro-Taper pushrods and Dual Piston cam chain tensioners are included with Axtell’s oil pressure bypass valve for increased life and valve train control. A pre-mapped ThunderMax® with Wave Tune AutoTune is included, allowing fast, dyno-free set-up without engine tune worries. High flow injectors are included with this kit (kit requires the separate purchase of a H-D® 58mm Screamin’ Eagle® TBW throttle body). For more information, . Tel. 410.579.2828, Fax 410.579.2835

    Nice total package that I’m sure will deliver the goods (for a price) The 110/CVO crowd could use something like this for added performance…just add wrenches!

    So why don’t they just do this at the factory while they are making the original engine. Can it really cost that much more for some different pistons and a bored-out head?

    Both Zippper’s & S&S are very reliable. Great stuff for those in the know.

    Why on earth don’t they offer a 113″ or 117″ version of this. If you have the cylinders off for machining anyway, why not bore to a larger size too.

    Not offering a larger bore option makes about as much sense as their ALL BORE 106″ or 107″ — it makes absolutely no sense to split the cases for those sizes.

    Mike. A new Harley has to be emissions and noise compliant. It also has a warranty.

    If you check these are off road kits, not legal for use on emissions equipped vehicles on the street. Meaning Harley can not sell them and if they did you could not get a license, insurance or a tag for it.

    It’s not that complicated. The premise of this package is to get the most from your 110″ engine WITHOUT bottom end disassembly or case machining, all of which are available too…@ 2-3 times the cost – including additional labor, machine services and down time… If you have a stock 110″ what’s not to like?

    You can do a 113″ or 117″ WITHOUT bottom end disassembly or case machining. What’s not to like more about that?

    Plated “Drop Ons” are an option. Stock, late style crank is always a concern.

    HD Rider. Please explain how you can convert a 110 to a 117 without boring the crankcase?
    As far as I’m aware the 110 uses a 4.180 spigot dia and most 117 have a 4.300 spigot.
    I can see maybe the 113 using a over bored stock or Nikasil lined cylinder with a custom piston and using the stock 110 case bore diameter.

    Cams, headwork and a good tune will give you all you need for a fraction of the price. I’m sure the power won’t be much less than this kit

    If you need nearly two litres to get about 80 RWHP,I say strip all the crap of a stock bike and go faster that way.

    When you combine a 4 1/8 bore with the stock stroke a 117 is born.
