Good morning all………I ride an 03’ FLSTCI with Vance & Hines Big Shots Staggered, stage 1 (SE breather/filter and download). The 60+/- hp just isn't doing it for me, and I would like to get some more power. I am not racing the bike at the ¼ mile track, and am just looking for some really good extra “get up and go” at the throttle.

I’m looking at the HD 95ci Big Bore kit. I talked to a HD Tech in Michigan yesterday, and here was his take on it:

They advise since I have done the Stage 1, I am putting out 60 – 62 HP. They can increase my HP to just shy of 80 (around 78 – 79), by doing the following:

Screamin Eagle 1550cc (95 ci) Big Bore Kit

Screamin Eagle Cylinders

Screamin Eagle Pistons (Flat top – high performance)

Screamin Eagle clips and rings

Screamin Eagle air cleaner and breather hardware

High performance clutch spring

Screamin Eagle 203 cam (really recommended)

Re-flash the ECM

Install and computer program a Power Commander III


They swear by the Power Commander, and do not recommend any HD downloads (just as I’ve read in some Forums). As well, they would not do a Dyno on the bike until AFTER the break in period. They also recommend (as did the other Dealers), not to replace the pushrods, as the factory installed rods are of high quality. In addition, they recommended NO head work. They advise that head work starts at $1,000, and is basically unlimited. However, as I have no intention of doing ¼ mile drags, they advise it would be a costly waist of money for my intentions. Their price - $1600 out the door including all parts and labor


Any thoughts or suggestions on this work? I am awesome at “chroming”, but am not very mechanically inclined. You’re an AWESOME and amazing group in here, and I look forward to any feedback you can offer. Thanks very much in advance for your time, I truly appreciate it. RIDE SAFE.

Call Dewey at Dewey Customs. Lots of satisfied customer right here on the board. A lot more bang for your buck.

Mike,

You could also call www.bishopsperformance.com they are in Redford, Michigan which is just west of Detroit. He has a page full of dyno runs from bikes he has done work on. He also ports heads, bores stock cylinders out to 95" etc....

Can save you some money and get you what you want. One warning. Talk torque and forget the horsepower. Read his site. Lots of good info on it.

Get the last few issues of American Iron. Donny covered these issues well. I agree with him that Head work is an important part of the equation. Check that info out and also talk to Doug at HeadQuarters. I am very pleased with my build.

Also check out HDWrench...GMR Performance. He is a site sponsor. He has 95" kits for under $1000 that will beat the dealer kits. Better performance, better price. How can you go wrong. Its worth a phone call at the very least. Then decide. BTW, with a cam with lift of .510 or less, you can get away with a street port job on your heads which will really wake up the engine work you are proposing, for under $300.00.

You won't go wrong with HDWRENCH or Dewey. Both sell an excellent product. Hard to beat that 98" kit for the money.

I'd stay away from that dealer...thats my advise.

a good cleanup of your stock heads; like bigboyz offers for $300.00, will help your motor produce a lot more power, and run cooler.

Since your heads are off for the big bore anyway, I consider it foolish to not atleast do some mild port work.

Also for a lighter, non-bagger bike, I would suggest you atleast step up to the SE 204, instead of the 203...which is made for an even lower power band in use with heavy baggers. That is if you stay with a SE cam (not my favorite).

If the tech doesn't realize you can get quality, non race, port work for your heads for under $1000.00...or that it would actually do your bike good, I would NOT want to do business with them.%[email protected]

P.S. I also agree the BEST bang for the buck is going to be HdWrench's 98" kit with his own mild head work. I honestly wish I had gone that route myself. I have a lot more money invested and probably less results.

Thanks for the info everyone. It seems that 95ci can produce enough hp and more important to me, the correct torque curve.

Only on occasion do I get the RPMs up into the higher range, I'm really looking for torque on demand in the lower and mid RPM ranges. I've never had my scooter over 75 and really don't plan on it anyway. What I want is that little neck snap when I hit the throttle or waking up the neighborhood dogs as I leave the stop light.

So 95 jugs will be sufficient... the question is what is the best combo to produce the best torque curve...

Which forged pistons?
Which Cams?
Which heads (the SE Performance)?

Thanks again for any info. you can supply. I REALLY appreciate it.

If you are stuck on 95" then:
My quasi-educated, non-professional opinion would be to have YOUR own heads ported by one of the previous mentioned sponsors, have THEM punch out YOUR cylinders to 95", Andrews 26G gear cams, 95" SE cast flat top pistons, and if your bike is injected, a DFO or SERT and dyno tune.
You can spend lots more for bigger numbers..the options are wide open from this build on up.

80 HP Big Bore...Really

HarleyMike, Really if you want 80 HP with the Torque right where you want it, save your money and just put an Andrews 37 cam in there. I did the 37B, SE Breather, Rinehart exhaust and a PowerCommander on an 88" and had 80HP and 85 ft/lbs of torque. The bike ran great and surprised everyone that thought I had a big bore kit in it. I'd be glad to show you the dyno run.

:huh:

I can't understand why people have to have the big bore if they only want a little boost. It's really not neccessary. However, if you want to rock and roll, for the same money you'd be spending, you can have Steve from GMR set you up or atke the advice of the others on this forum.

Just the Andrews 37 cam, add the Power Commander III USB, and a Dyno? This is starting to look pretty good! As you're aware, I'm not very mechanically inclined, and I TRULY appreciate everyone's assistance on this. I would be willing to stay with the 88, and just do the above (would the SE 203 cam be better?). I'll have to research into the Andrews 37B Cam & SE 203, and find out the best place to buy one. This may just be the way I want to go! I'm just looking for that "little extra bite".

What do you think?

Thanks everyone for the info! I may start at the above route, and as time (and $) start piling in, do some more mods (heads etc.). I think in the interim, this package may just do it for me! Considering I just dropped a mint on chrome, this route may be cheaper than a divorce!

Where does this maddness end? I thought I would be happy with a "stock" 03' FLSTCI................Well, after dropping close to $8,000 already on mods................it's an addiction............I think I need a 12 step program!

Seriously, thanks again for everone's help on this, i appreciate it! RIDE SAFE.

Be sure to do your homework before buying the 37G. The 37G in an 88" will give you impressive numbers, but probably not where you want them. You said you were not going to be going to the track, and that you wanted "get up and go at the throttle". In your 88" with the 37G, the gain you get won't happen until 2200 rpm and up. You also need 9.7-9.8 cr for this cam to shine.
A 26G will come on around 1800 rpm and works well at about 9.4 +/- cr.

Do what you want, just don't jump the gun. Talk to the experts.

YankeeBob,

What about the 31G cam with a .030 head gasket?

Bottom line is what YankeeBob said...don't rush into it. He's right, the 26G is a good cam, but the bottom line is that you don't have to drop 2-3 Grand on a build if you only need a thousand dollar cam, exhaust and breather combo to be happy. I rushed into my last build before I knew about this forum and have been racking my brains over a way to fix it. Check out the builds with the dyno runs even, then find something you like, Consult the experts, then have it built. God Bless and Enjoy!

I have the Stage I ac, SE 203 cams, and a PC III USB on my 2005 FXDX. The dyno numbers are 75 HP and 85 ft-lbs of torque. Maybe next winter I'll go up to a 95 inch engine, but I want to see how the power feels with more riding

From Andrews website:

Great cam for motors with 95+ inches and 10:1 CR.
Lower TDC lift means easy installation. Similar to 37G
but different timing. 2000-5800 RPM power range.


Note the 10:1 cr. Read...$$$ headwork.

I'm planning on head work anyways. Just trying to decide on a cam. Woods, Andrews, Head-Quarters, Crane, etc, etc, etc......

Right now the plan is the 98" kit doing 10.5 to 1 and that is all that is solid in my mind right now.:huh:
