It is rarely necessary but always smart to do. None of us have a crystal ball to predict how you ride. Horsepower and torque are not the only factor.

Don, I have two bikes, but I don't race it..
Long distance cruising at 80 90% of the time, but I do like to open her up between 110-120 on those lonely back roads to Laughlin and  Havesu...

That doesn't cause them to slip.
What does is shock load and a clutch that is doing its job with no slip.
Lugging a high torque motor is the worst or dropping two gears by mistake and letting out the clutch. Burnouts don't help.
A local guy with a stock 2003 88" slipped his wheels just stalling the bike 

You will get a whole gaggle of guys that didn't do any crank work and claim success.

My own personal opinion is it's wise to at least pin and true the crank to be included on any top end job especially a 117". This will give you the insurance the crank won't slip and its also a good time to address the rods by honing, and balance the wheels.

Will the SE 177" kit for 96" -110" twin cams fit the a 2002 twin cam engine that has the S&S 4 3/8" flywheel installed.  My bike now is a 107" using the S&S 4 3/8" crank.

Nope
The spigots are larger, needs a case bore but could be done
If doing that I would just use full spigot size (~4.370)x 4.125" S&S cylinders

Here are the results of my 117 kit build, 58 mm tb, 259e cams, hylift Johnson lifters, rocker lockers, no head work. I run Fullsac DX headers with 2” cores. It runs smooth even in low gears/rpms. I added the high capacity oil pan as well - adding 1.5qts. My goal was reliability with a torque boost. Exceeded my expectations on tq, time will tell with reliability.

Man, took me a while but I read the entire thread. Definitely going to do this when it’s time to replace my lifters.

Only have 11k on my 2015 RG Ultra, no tuner, stock head pipe and after market mufflers. Ride her for two up touring most of the time so I’m thinking I’ll go with the stock kit as it comes. Thanks to all for your detailed input!

.. Good looking dyno sheet. Should run for years .

Very nice build. Should put tons of smiles on your face for miles to come

Rob, the 259E cam likes more compression than comes in the kit.  So if you ran a thinner head gasket, or changed to higher compression piston, about 10.75 to 1 is what that cam likes.

KY  nice dyno. Nice to see the 259 worked well too. See so many comments that cam needs more compression and had me considering other cams with an earlier intake but yours breaks 100 ft lbs  at 2300-2400 and takes off at 3k.  Like it didn't run out anywhere. Looks like a nice ride especially with no head work.

GMS recommended the S&S 585 for me. Greg said They are easy on valve train and he doesnt like pressure from the earlier intakes.  Said on the dyno the timing needs taken out on the early cams and a bigger motor runs fine with a later cam. Not looking for everything that can be squeezed out and wanted to use the Harley flat tops (Malhe) piston at 10:1.

Sold off the 259's and getting their head work but would be happy with your results. Figure the S&S with two degrees earlier and more lift I should be in the neighborhood.

Bakon, some of the fun is making the decisions for your build and figuring out your goals for it. Looks like your builder is giving you good advice that should exceed my numbers. I’m thrilled by the 2300 rpm range above 120 ft lbs, and the full spectrum above 100. Totally different bike from the 110 ci which I had a lot of fun with too.
What did you go with for lifters?

[bakon]

Did sell off the new SE Lifters. I picked up some Feuling lifters at a local Harley dealer in sale last year for $100 on a discount rack.  Used them before at .650 lift with no problems and a second build at .560 lift for 30 k miles.
Not chasing any numbers with my build.  Just don't want to hurt low end either. I never run below 2k and cruise at 2500-3000 so your numbers are great to me. I do run up to rev limiter but that is rare. Most shifts at 3-4k depending on road and conditions. 5k when running it out for a minute or two. Always thought the stock 110 was weak when running it out. GMS says they are 80's hp and 110 max ft/lbs on them. 110's with their heads and 10.5 plus 585 are hitting 115/115 plus or minus a few. That was a stock throttle body. Be nice to be 120/120.
My goals were just to stay with 10:1 as we are cross country runners. Also didn't want to build lower end up.

Lot to be said for that type of build. You never know out on the road what you may or may not find for fuel. Its nice to be able to pull up to a pump.and 89 be the best there is and know you can filler up and run right on down the road
