First things, I'd like to say hi to everyone and I hope to learn a lot of good things on this forum. I'm investing in the Fat Boy Lo this spring and have been trying to gain as much knowledge as I can about the performance I want to have with it.
After looking at the different stage kits that are offered, the two choices that I've narrowed it down to are the 103 stage II and stage IV.
I'm no motor head and I've read a lot of different opinions on here about different cams. And the bike will be purchased with the kit installed and tuned so outsourcing cams from a 3rd party and having it installed with the kit is not ideal. So here what it comes down to.
I've ridden a 09 CVO Springer and liked that power it had and I want to make sure that I'm not losing any from that bike. The 110 comes with the 255 cams but compression was 9.3:1 and the 103 will be 10.5:1. Which cams should I get with the stage 4 kit?
1. Don't care about going speeds over 90-100 mph.
2. Will not be track raced or ridden extremely hard consistently.
3. Exhaust will be V&H Big shots staggered. SE Heavy Breather intake
And here is the package I'm looking at. Thanks people
SCREAMIN’ EAGLE® PRO
STAGE IV KIT – 103 CUBIC INCHes
Here's a 103 cubic inch racing kit that puts it all together
for you. If your looking to build a fast, track ready, 103 kit
and want to buy all the components you need to maximize
your results, here's the kit! This eliminates the guess work
on what components you should use and what works well
together. We've put all the components together including
SE performance heads that provide a great performance
upgrade for a 103ci at a very attractive price. Kit includes our
high performance / high flow Screamin’ Eagle Performance
110+ Heads which include large intake valves at 2.120" diameter
(our biggest ever), high compression forged aluminum
10.5:1 pistons matched to the 110+ heads, an SE260 cam to
open the valves appropriately, allowing the right balance of
air and fuel to enter, Perfect-Fit Pushrods to accommodate
the higher cam lift, a 58mm EFI throttle body to get that air
flow to the heads, big 3-7/8" diameter highlighted cylinders,
then topping off this kit off with a “must have” Super Tuner
to provide the right tuning capabilities. Kit includes gaskets.
For race application only.

It's not just the cam that makes this setup come on late
This is a high rpm setup and not conducive to this 6speed bike IMO. Not too many are happy with these when they are done and I have recieved a lot of calls from guys wanting to know how to get their low end torque back. Those heads would be right at home on a 117"+ motor but will be very slugish with that bike and the gearing they come with. All the power will be from 3,500 up.
Consider using the SE MCR heads and have them opened up (chamber) or use the stock heads ported and a shorter cam. Setups such as this can make easily 110/110 and have a very healthy wide torque curve that comes on right off idle.

Welcome, and what Don said!!

Thanks for the advice. The more I read on this the more I realize that this maybe isn't the kit I'm looking for. Might as well stay with the Stage II and maintain warranty because I'm not looking to run RPM's consistently high. It sucks that HD sells this "kit" as if were almost plug in play with great performance. Or maybe the target audience is a small few with a heavy bike, IDK.
So, if I were to have these heads below installed and opened up, what else what I need to complete it? race tuner, etc.?
Any good options to have these opened up in the Midwest? And/or would the Stage II kit with maybe a little mod be better off?
I'm guessing that if the warranty would be out the window if I had the motor running 115/115. But those numbers are what I'm looking for, just before the 6500 range. Also, what is the most common air cleaners that assist in producing power?
Sorry for all the questions, just want to get as close as possible to satisfaction when it's all said and done.
Thanks :)

I think you are on the right track.
First thing is to figure out what kind of riding you do, and what you expect from a build.
Next, figure in your budget.
Then, figure out if you or someone you trust will put it all together.
Doing homework will help you in the long run.
Keep us posted how things are going, sharing information and success is always welcome here!

The results I'm looking for is to be quicker than the 1010 CVO Springer that I loved to ride. It had exhaust and tune, but other than that it was stock.
I did look at the Stage III kit at first for a while, but still it seems a lot of people are not happy the way it comes and end up digging deep. Stage III also voids the warranty, so I figured if I was going to void it with the Stage III, why not spend the extra money and go with the IV. But even the Stage III and IV still show the same power until around 4000RPM and up, which I'm not in search of. Would be nice and all, but maybe throwing some other Screaming Eagles parts together for around the same price will produce better results in the quicker numbers from the 0-60 range. If I have to go elsewhere for a set of cams and to get ported, thats fine. But I would like to get everything installed and tuned together and be happy. I know that I can save money, better products, and on if I go to a 3rd party but I would like to throw these parts and tune into the purchase of the bike.

Best bet would be to check with some of the vendors here that do this for a living, ask them if you can talk to one or two of their customers for feedback.
I spent 31 min. (just got my phone bill!) talking to a member here with similar riding style as me, and a build I am considering on my '10.
I will probably go that route even though it will void my warranty.
Just me, but, it helps to do some research.

Thanks Mike. There sure is a lot of different opinions on these forums and a lot of good information.
I've been searching for different results that people have had, all good stuff.
If there is anyone that has the results I'm looking for, please help me out. I take two cents at a time too! ;)

Hey Semperfi82 Welcome to the site glad you have joined us when you can go by the New Member Introduction (http://www.cvoharley.com/smf/index.php?board=30.0) and Introduce yourself over there.
Thanks

You can have this bike stomping that CVO for not a lot of money.
The plan
107" Pistons and stock barrels bored for them
Street Pro or Pro Street head package on the stock heads with compression releases, or SE $949 dollar MCR heads opened up to 84-85cc, clean up ports
Woods TW408-44 or TW8-6 depending on the level of headwork
51mm HPInc or SE 58 two piece TB optional
10.3-10.5/1 compression
S&S Roller rockers with the TW8-6
A good pipe which is not the V&H Radius or especially not the V&H Big Shots
A good pipe would be the stock head pipes and Cycle Shack slip-ons tapered, FatCat 2 into 1, Basanni Pro Street, Thunderheader. There are others
TTS tuner
A good tune by a qualified tuner
A performance oriented HD dealer will cover your motor as well as the bike if they do the work and forget about the Stage whatever packages.
This motor work will just be covered complimentary by the home dealer not on the road officially however.
Change your gearing 70 rear pulley and a 30 front.
Now you have a ripper that is streetable and reliable

Mike, keep us posted on your 2010 103" plans. I'm running the same stage one from Fullsac and would like to take the next step.

I just fired it last weekend.... It hasn't seen a dyno yet.
Can't wait....but it's February in Northern Illinois....gonna be a bit before I can get it out of my workshop....snow has to melt for sure.

Scott,
What's the CCP and Corrected ?

who you gonna have tune it, was a post on another site that John Golden was no longer tuning :nixweiss:

Don't know... There are no real standout tuners near me. Something I have to figure out yet...
I understand John may still tune at his location...just may not be traveling so much.
-
That would be good if he will still tune locally without travel as you said that area is kind of sparse for tuners.
-
who you gonna have tune it, was a post on another site that John Golden was no longer tuning :nixweiss:
John is no longer traveling. Or perhaps with only minimal exception. Still tuning locally. So Scott can crash here for a weekend and get it done.
