107 inch?
I see there are quite a few guys here with the 107 engine and I plan on doing the stage 2 this Winter after riding season ends. I've seen the 96, 103, and 110 on Harley's website, but no 107. Are you getting the 107 after doing headwork/boring, or where is this displacement coming from? If you've got a 107, could you please explain why you decided on going that route and what it cost you? Also, what is the HP/TQ difference you got with the 107 over the 103? If it's numbers are good and the price is comparable I'd definitely consider it.

107" is the largest bore you can go without boring your cases. You don't see on HD's website, because they don't make a kit for it. Aftermarket is the way to go- GMR Performance, Head Quarters, Hillside, etc all do 107" kits. The cost is comparable to a 103" kit, and makes more hp/tq (if set up correctly). If I was starting back at square 1, I'd definitely go with a 107" over 103."

Yep, most of the builders have 107's available, and most will either bore or have Axtell or Millenium cylinders available. Downside of the 110 is you gotta split the cases to bore them to accept the larger cyls. If you are going that far, you might as well go to a 113 or 117. Same amount of labor and near identical in cost .

Done right, the 107 well tuned with a good 2-1 Supertrap will deliver #s that are very impressive. That's my choice at the moment and reasons for doing so.
