fellas I'm looking to do a build on my 103. Its built decent right now it makes 109 HP and 113 foot pounds. It runs well. More is always better in my book. Im looking into big bore kits. I was wondering what is the best bang for my buck is. I seen 124 kits up to 131 kits if I'm correct. what do all you recommend? I still want it some what streetable as well. what kind of power do some of this kits make? If any one has a complete lists with line items so I can do a little research on these on products that would be much appreciated. Any information is GOOD information thanks again.

I've had great results with S&S' 110 kits. 127/127 was the lowest one so far. 129/130 is typical
with my heads and a good pipe. One of these has close to 30,000 miles on it and still runs strong.
that one made 129/129. The sheet is on my website, and there's another one on MCE Performance
FB page.
You have to bore your cases to go any bigger than 110. I start with the stock 103 heads and work
them over heavily, custom made Manley valves and Manley's springs, I've had great results with
all of them. fyi....
-
Properly done, the 103 ACR heads work extremely well on larger than 110 too.
Over 120CI the SE110 heads are a good place to start. But they're really too big
for a 110 that's not going to be spinning above 6000 on a regular basis.
The SE110s need even larger valves put in them to get them to work right. The
throats are just too damn big in stock form. IDK what Harley was thinking when
they did that.
-
It is easy to just do the heads cam and throttle body. Even my cheapie heads will get you 120 sq or close. Stock bottom end

124 kits making 131 is nothing to write home about. I've been getting 130/130 out of 110 drop ons. Using re-worked 103 heads.
A 124ci a should put out north of 140 square.
-
You should be pretty close to 120/120 now (with 103ci) (If the heads are half-way decent).
If your heads are stock, I'd say you're doing pretty well.
-
Matt notice a trend? Guys buy groups of parts above and beyond the stage the hd stage kits results are the same or less. Then this is tried to be molded into the new normal. Look at the hp/ cu. in.
-
So a 103 with stock heads makes 120?

i do believe he was talking about 124ci to 131ci. not a 124 making 131....

Yeah, I see that now. My bad, misread it. (I'm trying to do 5 things at once)
I'm saying a 103 with a decent combination of parts and tune should be close to 120
Like high teens.
There's no mention of real specifics besides "its built decent". 109/113 is not horrible
but I have no idea what all has been done to get to that point.

Matt, and that is without head work?
-
103 can get their (or a bit more) with head work. I didn't try it without.
The 103 in my old 05 was built around Mackie 598 cams. 107 in build with those cams and some nice head work. On different machines (one I knew and trusted one was a normal "oh we're at a rally let's waste $40 and loser buys the beer) had comparable numbers. It was in to the low 120s but would suffer slight bit of detonation in really hot weather. Just because I'm impatient with such nonsense had a little timing out and it ran reliably and really well running in the high 1-teens. Would do that all day long and did so on long trips and a couple thousand mile days. Man I liked that bike 8) .
-
Ok so we are getting closer to reality..
05 5 sp bike, less drag than a 6 sp bike
250deg cam, healthy. I am sure there was a head package with that build that was not of the budget variety. And also sure there was a healthy amount of compression to get there and a larger TB likely.
-

Here is my build. I can't say enough about it. Whole new bike.

Definitely so. Would never have gotten where it did without it. Some nice head work. Best amateur's math had it in at about 10.25:1. Only a 50mm TB though. Didn't want to start trading bottom end for top end.
-
So far I have mild cams, air cleaner, tts master tune, vance and Hines short shots, heads are stock. Id like to get in the high 120's Horse power range if possible. Mainly I'm looking for tried and true builds / advices. What kit to get 110, 124,131. Money is not an issue but always would like to save money where I can. If the attachment worked heres a pic of the old gal. Fellas I appreciate all your information.
Thanks Brandon.

Head work.
-
I would say to get to high 120's your going to have to go to 113 - 117 to get there. Both of which or anything bigger and your going to have to bore the cases. Low 120's for a very reliable 110ci. My experience/my opinion only.

Since you mentioned 124" -131" do yourself a favor...have a repritable builder build your motor to 124" and get everything you want. That will be your biggest money saver. I did it the hard way. There are a few great engine builders out there. Kendal Johnson, Greg Dahl to name a couple..I suggest Jim Libonati @ Mega Flo. My dyno sheet is on here somewhere. It now has 25k on the motor and I tour with it! Good luck

I'll have to respectfully disagree; I've been getting 129/129 out of 110s pretty consistently. (using 103 ACR heads)

Besides heads I build engines. The pipes will have to go. I can recommend what will get you where you want to be at. Mild head work with a 1.9 valve, added compression and taking your motor up to a 113, case bore required, with your crank reworked would be my approach. It is a softail so a concession needs to be made for that. They are a little down on power vs an A motor.
-
What pipes do you guys recommend that give you the most Power. Im leaning towards that fuel Moto 110 kit possibly. still diving into research. Fellas many thanks again with all the feed back it is very appreciated.
-
If you have time for it, great! (I don't)
There are LOTs of very good engine builders around here. They're factory certified techs running their
own shop or working at dealers.
They do all their own work including tuning. So there's no need for me to be doing it (even if I did have the time).
I used to build them here, but machine work and R&D eats up all my time. I can't even get around to putting my
own engine together, the machine work is done, but it's been sitting in boxes for a year.
Everyone's situation (and preferences) is different. I just don't have the time to be building the motors right now.
(I'll probably get one of my customers to do it)
Cheers now,

Do you want to stay with duals? Or is a 2->1 an option?

A D&D Borezilla works well on 110ci, RB Racing has a good reputation, and Frank Drago makes some nice stuff.
Generally speaking, A 2:1 with stepped, equal length primaries will give you great TQ over a broad RPM range.
There are many good pipes out there.
-
pipe wise it doesn't really matter to me. Looking for what makes the most.. Looking to dude this little build over winter. I have a few good minds helping me. MCE do your recommend the fuel Moto 110 vs the 110 S&S kit. which is a better quality product?

I've only used the S&S kits. One of them has 30,000 miles on it and was still going strong until he
had a valve spring break but it didn't destroy the motor. S&S makes the liners from steel. They're very
durable. Don't know anything about the FM ones.
Hope that helps.
-Matt
-
I could be wrong but I believe the FM cylinders are S&S
-
I had heard that. I'm pretty sure he's not making them himself. But who knows?
-
The s&s 110 bolt on cylinders are no longer steel....some form of centrifical cast iron
If you want an honest 130/130 build a 113/117
Last one that left here with a pretty mild cam made 129/141 with a junk eBay Dan Moto pipe
-
if your looking for good HP/TQ but still truly tour & do long distances on the bike,i would really look into doing a 124",even in a very mild build,your going to do more than a aggressive build 110 and have tons more reliability.we do a lot of 124" here,starting at 3500.00,feel free to give a call
-
Kirby,
Are those the heads you're using on the 124s? I'm curious b/c we were thinking of trying
those on a 124.
(+1 Adding displacement is the most reliable way to increase TQ)
Thanks,

Just kidding...

No,just a old pic.I like the 110 heads for 124 builds.I have use many 103 heads with very good results though
-
Thanks for the reply.
We want to try some 103 casting on a 124 (or 117) to capture some data.
The models I've made seem to suggest that they can work just fine. I just
want to try it and see if my theories are correct.
-
just as the 110 heads chamber is too big for most smaller builds,the 103 heads are too small for most 124 builds.not a deal stopper by any means,just more work for each build
-

Part of the plan is to open up the chamber Kirby. I'm going to un-shroud the valve(s) while adding chamber volume.
No surface milling in the cards (other than maybe a cleanup cut). We'll get the chamber figured out as we get closer.
Thanks!
ps: The goal is to make a Torque monster for street/cruising. (not a high HP engine, but we'll see where that ends up)
-
can any one send me a link to what the think the best 110 kit is or what I would need. 2005 Fatboy cvo. Will my heads work this with if I get them massaged over. Or do I need a new set? I contacted fuel Moto and this was there response. Quote
"Brandon
Thanks for reaching out to Fuel Moto. Sorry to say we do not have a 110 kit for your 2005 Softail. We do not have a piston that mates up with the cylinder head used on the 2005 CVO 103.
Please get back to me with any questions.
Thank you.........Bob"
As always Many thanks fellas !!!!!!
-
Fellas here what I was thinking about getting. Please give me some feed back or point be in a better direction. See attachment.
Also need to know what I need to do with my heads with this or if I can use them. Bob from Fuel Moto says the heads in that kit wont work on my bike.
Thanks Brandon
-
Brandon,
Get yourself a set of 103 take-offs and have them worked over. I've done (the machine work on) quite a few,
they get anywhere between 126/126 to 130/130 depending on the pipes and TB used.
The engine builders used the S&S conversion cylinders on those builds.
-
what do you think of that Kit above
-
buy the time I buy a set of heads for evil bay for 200, have them massaged I'm guessing 500 to 8 or 900 maybe. then throwing the goodies in them. Would I be better off just buying a new set of S and S heads done up?
Many thanks
-
I hate to say this, but S&S' heads aren't that good. in fact they're terrible (their "Super Stock" heads anyway)
You'd have to put a bunch of work in them to make em decent. So, in short, NO!
-
thank you sir I appreciate your honesty.
-
That was really hard for me to say publicly, but I have to be honest. Generally speaking, S&S' products are
very very good. But those Super Stock heads are severely lacking. I don't know what they were thinking.
-
They can be modified to make them work really well, but after it's all said and done, you're better off
with a set of 103 heads.
-
Have MCE do your heads trust me you won’t be disappointed
-
Sooo these would be a good candidate to massage up??? Im sorry for all the questions but again thank you for the knowledge!!
See attachments.
-
I am and will be in the market here. Might run them down the GMS Racing and have Greg do them up there like 2 hours from me. I have herd a lot of great things about them guys. MCE could be a potential candidate as well . Like I said early in this thread I trying to find all the info I can from the educated on this build I want to do. MCE what do you guys charge to get the heads done up??
-

Can't go wrong there. Don't forget Mega-Flo is in Portersville, Pa which is about an hour and a half North of GMS depending on where you're located. Good luck

Good evening I would like to get more information on The S&S 110 kit. I have a 2005 Electra Glide CVO with the 103, 2 into 1 thunderheader and rocket cam 554 installed. I’m thinking about a Big bore kit and some head work, but can’t get a definite answer that the 110 kit is 100% bolt on for my cases .
Does anyone on the thread do headwork close to Savannah Georgia??
