Hi Guys

Does anyone know the HD part numbers for the 117cu Cylinders alone (not the whole kit)?

Ride safe.

fwiw: I'd recommend looking at S&S' cylinders too.

92500051 gets you just the 117 Cylinders & Pistons for $1072 online at Board Tracker Harley. Been looking for the "cylinders only" myself with no luck so far.

Can't you bore a set of 110 cylinders to 117?

[HD Street Performance]

Sure but would you run them? Do the math, the spigots will end up at ~.028" each side

It doesn't seem to deter people from doing 98s and 107s. What's the difference?

Regarding crank runout and reliability: Procharger (we're a dealer), Trask (at the other end of town and we see a lot of them), Magna Charger (a riding buddy has one), and Aerocharger (installed some of them) all sell bolt on big power kits over 160HP. We've seen a lot of all of them running for years with stock cranks (that's how all of them advertise their products for use and installation), also high performance N/A  builds all over town too. Seen head gasket, detonation, and driveline  issues. Not seeing crank issues here so far except for the clutch dumpers and downshifters, and several of those guys have stock bikes with just slip ons and an air cleaner.
If you have enough HP to have traction issues, you generally don't have enough shock load to hurt the crank
 unless yu are one of the folks that insists on downshifting and that's what I have been seeing causing most crank issues HERE.
These are MY experiences in my locale. Circumstances alter results, nothing in this life is absolute, except death. We check, but don't obsess over runout. Feel free to disagree, but don't judge me for my opinions based on what I have seen.  TIMINATOR

Good to hear. I'm still thinking from 07,08 I guess. As I still ride my 07.

Those spigots are .058 per side.
Steel vs cast iron

Last time I measured one, which was quite a while ago, it was more like .038"
(I wouldn't be uncomfortable with them if they were closer to .060) That's why I
don't like them. And last time I checked, the 103 cylinders were cast. (as are the
95 cylinders)

Buy the drop in 117 cyls, pistons, rings, pins and retainer clips. The cyls are tool steel and hrder than the hinges of Phoenix in the summer. They work fine. I'm making 135.84 HP on pump 91 for nearly a year now with no issues. Before that I ran the drop in 110 setup on my CVO Fatboyat 121 something. It has been 108 degrees to 118 degrees for the last several weeks here, just typical July temps so far. We have done a bunch of those thinwall kits with no problems here in the heat. We do sell and install Amsoil in all of our builds, it does let them run a bit cooler. When you zero deck the jugs you will gain an appreciation for how hard the liners are too.   TIMINATOR

Thanks.. What exhaust are you running w your drop in? Air cleaner as well?

Thanks Hunter

Yes, I did my build just buying the black cylinders.  I had CP make custom pistons

[MCE]

Tool steel would be the way to go if one were dead set on doing this.
(I would re-consider it unless you absolutely just had to have those 7
extra cubes)

A 110 done up right should get you plenty of TQ (and HP). But it's
ultimately your choice.

Boy, that's no lie. Cutting those tool steel liners for zero deck lets you know how tough those sob's are.
I've been cutting the bottom mating surface to get around it.
