I ran into another k9 owner at a party tonight we got talking bikes showing pictures and stuff. I have a 2010 he said he toured the factory back in 2007 and they told him the 117s were really 124s..... so is this correct?

I never go inside an engine so forgive me if it sounds crazy. But will swapping the piston heads turn the 117 into a 124 ?

No..you'd have to change the crankshaft, not the heads on a 117 to create a 124--by giving it a longer stroke (4 5/8"--) see SMCT above. And note pistons and heads are separate ideas here.
you could bore out the cylinders for a few more inches too, but the longer stroke on that 124 is what makes it sing...at least the one I rode had tons more power than my K9 (decked, 585 cam 2-1 VH)....it was a smoother, too.
BTW--the Baggers have the 111' which s a 'square' engine. That makes plenty of torque because the bore is identical to the stroke (4 1/8 X 4 1/8).
And to my knowledge, BDM made a switch to the 117" engine (someone help with the date here) and used that exclusively. I never heard of a stock Big Dog up to 2011 with a 124....
Matt Moore started using the 124" engine in the new Big Dogs (at least in the K9's). See Bigdogisback.com for options.

i think '04 was 117" option with 107" standard, then '05 went to straight 117". never a 124" option until the new 2016, but i've been wrong before.

yes, the X-wedge and the 111" in the bagger were part of the "hybrid" bike line-up but for me, i generally don't think of them as the standard, more of a specialty bike. the 107" and the 117" were what carried BDM from start to finish, but would certainly like to hook up with one of the new ones with the non-EPA 124" just to see what the 117" should have felt like.
