Laidblaw compares a 114 RKS vs a 107 RK in this vid. Lots of features wont matter to you, but they do say they feel the motor is about a 10% difference in feel.
Specs say:
107 = 111 lbs TQ @ 3250
114 = 122 lbs TQ @ 3000
Id say its noticeable....

This graph was created from the following two graphs that Harley published in the parts & accessories catalog. I took the stock numbers from each graph and transcribed them to Excel and plotted them, resulting in the graph given above.
So, pretty much however you slice it, the 114 delivers about 8 hp and 10 ft/lbs more than the 107. Considering the 114 is about 7% more displacement and uses the higher-flowing Ventilator air cleaner, the results pretty much match up with what you should expect. (Ignore the Stage III and Stage IV numbers, those are irrelevant for the purposes of determining the stock dyno graph data that Harley published).

So to the OP a Stage1 on a 107 will probably not get the 8HP/8TQ without an aftermarket tuner and dyno time ,so no warranty if you go that way.

Again, both great motors...but since he’s asking...
people who who are happy with the 107 know what they wanted and like what they got. If you Don’t “know” you will “wonder”...and if you don’t get the 114 you will always “wonder”...
The 114 is cheap peace of mind mind and more power as well...double win.

Someone will correct me if I'm wrong (too lazy to look it up) but the 114 is bigger but the compression ratio is less. So yes, while you get more cubes it's not a massive increase in power like if you took your 107 and made it a 114.
Not only that but the price difference and the beating you take at the dealership on trade is simply not worth it (performance wise).
Just my 2 cents
