96 build options
Im curious to hear some thoughts on this scenario.
say you had a 96 with crank issues and possibly transmission issues as well, but you had a limited budget.
would you
A: bulletproof the bottom end with a pinned and welded crank, bore out cylinders to 107 and install a DD7 to address the transmission issues and gear ratios
or
B: bulletproof bottom end with pinned & welded crank, bore to 117 and replace all the items that needs to go with that large a bore and just rebuild the stock transmission.

I'd go A-1 and B-2....
Take care of the crank (Dark Horse comes to mind), bore to a 103 and rebuild the stock transmission... (I'm a little leery of going to 107" from 96" barrels, but I tend to be cautious... same reason I took my 88" to 95" instead of 98")
You can add a few primary bits for the added power if you like, such as heavier clutch spring and/or an AIM variable pressure plate. If it's gearing you want to change, you can also do that in the primary, with the engine sprocket or clutch basket teeth changes...
FWIW...
I have a 124" S&S at 135 HP & 151 TQ going through the stock clutch/basket and OEM trans. I have a stiffer clutch spring with the AIM variable pressure plate and a solid engine sprocket (32 teeth, OEM is 34 teeth). I am not one who "beats" on my bikes and everything is holding up very well...
Good luck with your build...

I was thinking the same thing. "Limited budget" and "bulletproof" do not belong in the same sentence.

limited in the fact that a 117 build will require more items and have costs associated with it than the 107 would, there by eating away at the funds for the DD7.
Ride safe!

I guess it comes down to the actual budget and what you really want.
If I were all the way down to the replacing the crank (best option) then I would go all in on a 117" but that will also require larger throttle body and injectors with head work to get the most out of it.
Otherwise I would go the "take-off" route and be in it for less money.
Good Luck!
