I think the majority of the members (including myself) that split cases and reinforce the bottom end have it done by John's shop at Dark Horse.

........your looking at around $1,300 to have timkin and everything balanced/bluepirnted and crank welded. I had them disasseble and put mine together too (was around $200).

 

Thanks! It's an s&s crank welded with timken. With a stout 106 or 107 you could definitely achieve your goals.

 

I remember reading about dark horse. Not sure if it was your write up or another one. Unfortunately I'm all the way in California, but still something to keep in mind. I dig your gray cases with the black heads and barrels, I've been planning on doing the same. It's gonna hurt to shell out the extra $1500 or so but I want to do it right

I may look into that crank. I've seen a fm 107 kit in person and I'm pretty weary about going that route. Cylinder walls are razor thin and the cylinders I saw had a huge wave in the middle of them. They had to be sent back to fm for another pair. I don't know how much more I can stroke the 96" to gain some cubic inches. Time to start researching!

 

The same stroke of the stock 96" (4-3/8") is used in 103, 107, and with cases bored to accept larger cylinders 110, 113 and 117. All just different bore sizes, so no need to go with a longer stroke unless you're looking for 120"+. You can get some flat top or dome cp 107 pistons and have your stock cylinders bored to fit.

That's my goal lol though I don't know if it'll work with an 2001 model. I e been finding out its limited to a lot of things....

 

Not really but you already have tim.. bearings any way.
They stopped using the tim. bearings in 03.
2002 was the last year they used them.
Since it is a 01 you will have to bore the case to use the 106/107 cylinders anyway; might as well go ahead and go 113 etc... You will need a stroker kit.
The 88 and 96 uses the same bore and cylinders.
I may be out of turn here but I would consider going larger since you have to have the case work done any way. I finished my 113 last spring. It was a 2005 88ci. Bored the case, welded the crank, pinned, and balanced with light weight H rods. Stage 5 head work, SS585 gear cams, pro clutch-like I posted-Baker OD6 transmission.
I can say this, I have a SS106 wide glide this is a fun bike and has plenty of power. When I first rode the 113 when it was finished all I could say was wow! It will eat my 106 for breakfast.
I suggest you to do a lot of research.
Talk to known good builders.
The main thing you want to accomplish that all parts are working together as a whole.

 

DIRTBOBBER if you dont mind me awsking have you dynoed your 106?

 

When it was first built I did. I am fixing to have both my Dyna bikes dynoed now that they have enough miles to finish the tune.
I was waiting on finishing the 113 and getting enough miles on it to check. I have a Street Glide I need to have tuned and it is a pretty good drive so I am taking all 3 at the same time to get it all out of the way.
117.8hp with 122tq.
Cams hit at 3,000 rpm's. When they hit hang on.
Either way a good 106/107 are good choices. I play with Honda VTX 1800 bikes just to break my boredom. LOL

 

Larger then 117? I doubt really want more then 130 hp thay should give plenty of bikes a run for their money. But good to know I can go that big and hopefully I'll be able to this coming winter

 

Well yes
120, 124, 131
