Can the Average Joe install big bore kits?
Good luck
To the OP, spend some time on ewe toob and get the service manual for your bike.
Familiarize yourself with the electronic version (ewe toob) and the book and give it a whirl, you may end up pleasantly surprised.
A good set of basic wrenches an inch pound torque and a foot pound torque wrench will be invaluable and the bearing pullers for the cam(s) can be sourced via the swap section.
Maybe someone local who wrenches might chime in and offer up a lift and a learning event too.
Or ask around local who works on their bike who might assist for compensation within reason on working with you on your bike???
Save the six pack for after the work has been completed cause diving back in after several wobbly pops might not be a good option.

Having said all that but stepping back a bi, I would ask the OP what his goal is and whether or not the goal can be achieved another way? I am thinking that with a good set of ported heads, matched up with a new set of .010" over CP pistons to establish a true cylinder bore, the SE 58mm throttle body and a new cam set, the OP can achieve the same goal for the same, perhaps even, less money particularly since the OP is considering taking on the project himself. Of course, there is no 117 badge to display by going that route. We have two forum sponsors could provide the machine work as well as help the OP with cam selection for a set of parts that play well together. The HD 117 kit might make 115/115 numbers but going the other route, the 110 rebuild could easily make 120/125 numbers.
As for paying a professional, that has not always worked out for some forum members. I am fortunate to have two true professionals in my orbit should I ever decide to let someone else work on either of my bikes but all of us are not that fortunate. Before the OP makes that decision, he must be absolutely sure that the professional is a true professional that can guide the OP in making good decisions and that will stand behind his work. To summarize and JMHO, pass on the HD kit, develop a build plan with one of our forum sponsors, identify a competent tuner (hopefully near by) and plan to DIY the project.
The OP did not mention addressing the bottom end, exhaust or fuel management; all important and should not be overlooked int the overall plan.
If all of that sounds like too much worry, I'd just pay someone. I've done all this myself many years ago, and honestly, now I can afford to pay someone else to do it, and I spend my time pursuing other hobbies rather than weekends on the lift.
Just my .02.

I'm with DJL. There just isn't any "kit" from HD I'm interested in. Any boring I have done is completed by someone who knows what they're doing and they have the pistons (good ones) in their hand. They're also going to port the heads for desired outcome. If it has to come apart, I leave no stone unturned.
