    Big Bore Stage II Kit For EFI Models - 103 Cubic Inches is rated 5.0 out of 5 by 2.
    Rated 5 out of 5 by from A BIG difference! I had the version of this kit that is for my 2010 Wide Glide installed by a pro, and I am VERY, VERY happy with the results. The bike makes a lot more power overall, especially in the usable ranges for normal riding and passing. I also added a high-flow air cleaner and a high-flow exhaust system, plus you will need to re-map, and finally I went with manual compression releases, to help the stock starter deal with the extra power. The additional power and improved throttle response the bike has now is outstanding!!!

    Rated 5 out of 5 by from Awesme Addition I would recommend this to anyone that wants to get more power from their 96. I put it on my 2011 Heritage and it added over 20 HP to my bike. I have so much power now it is totally awesome. Best money I have ever spent on my bike. I wish I would have went for the 110 kit.

    Q & A

    103 cu in Stage 2 level of performance, for a 2010 FXDWG?

    This 103 cu. in. Stage 2 kit isn't offered for my 2010 FXDWG. What could I add to the FXDWG 103 cu. in. Stage 1 kit to get this Stage 2 level of performance? For example, is it mostly a matter of a hotter cam? Thanks!
    Asked by: WideGliderRider

    If I purchase this kit will i be able to use the exhaust I have currently on my 2009 FLSTC?

    Asked by: bigkayne
    You can run stock exhaust, but you won't get the full benefit of the upgrade. The bigger 103 jugs, 255 cam and high-flow air cleaner let in more air and fuel, so you need a less restrictive exhaust system to let it back out, to make "maximum" power. You'll also need to remap the programmer whenever you make these changes. This will re-tune the engine to match the new changes, to make your engine run correctly. I put this same version of the Stage 2 kit on my 96" 2010 Wide Glide and it made a BIG improvement, especially in the usable power bands for normal riding and passing. I also added a compression release to help the stock starter deal with all that power. VERY GLAD I did this kit, and the bonus was it also helps A LOT with more power when riding 2 up.
