Fatboy 88ci, upgrade

Is it a big job to make my 88ci into 95ci ? I have a set of brand new pistons and cylinders off a 2009 But I think these are the same as I have now, am I correct in saying this ? If I bore them out to fit 95ci pistons and keep the rest of the engine stock will I see any difference and how will it work ? Is it worth doing ? Am I going to have problems with it after I do it ? A buddy told me that you have to change the cams after you do this to get it to work correct. Any info would be a help, THANKS

Question

ARe you gonna do the work, do you have the tools and know how.

Do you know how to put packages together.

And how long are you will ing to have yer bike torn down.

Where do you live.
What kind of riding do you do and what are you wanting out of a build

If the '09 was a 96" cylinders are the same but the pistons aren't, wrist pins are offset for the 96's longer stroke...Andrews TW26 is another good cam to consider...it is worth doing and will be as reliable as stock with a mild cam...

It's a fuely any changes with fuel pressuer or timing ?

My '05 Fatboy is a fuel injected 95 cu in. I have to tell you that I walk away from 88's and even stock 96's. Of course I have some mild up-grades. SE breather, SE cams and SE II pipes AND yes, the fuel requires re-mapping although mine was done with a Power Commander.

If you're staying stock a dealer flash should do you... if you add a breather,pipes and cam(recommend all 3) you'll really wake it up,then I'd suggest a PCIII from Fuel Moto,they send you a custom canned map for the combination you have...

Dynojet Power Commander

I'd figure out what I'm lookin to do with it and how much money you have to spend.
Would start with a cam plate change like Hotroadking said, then a cam and a Thunder-Max.
With the upgraded cam plate you will git a new upgraded oil pump with it too.
You will git more from a cam and a good tuner than anything.
And this would be the cam mfg too along with the cam plate.



And I would call somebody to talk about all of yer build, weather you do it in steps or all at once. And this is who I would send you too. And So would Bobby Woods.
Scott will make sure you git the right combination of parts so everything works together in harmony.
And if yer doing a 95cu, I would talk to scott, I might even look at a 97cu

Hillside

If you don't want yer bike torn down as long I would git a kit or send a spare set of heads and jugs to him.
You can also git the Woods Cam from Scott, he is a Woods authorized distributor.

But replace yer lifters when you replace yer cam.
If you git a copy of American Iron June 2011 you can see where one of Scotts workers is showing drilling 2 1/8 " holes in the lower Rocker supposts. I would make sure I do this.
A lot of folks don't even know to do this. But the guys at Hillside cycles ain't regular guys. They rock.
That's why I asked you where you live.
I'd take or send the bike to them or the motor and let them build it.
They are really good. But they would have to ask you like I was trying to do a lot of questions to make sure yer happy with what you want yer bike to do

I've got an 05 Fatboy that I upgraded to a 95 in late April of this year, it rocks.
I did the cam up grade in 07, so all i had to do was the pistons, I choose to bore mine rather than buy cylinders that were bored. I had Outpost H-D do my work the service manager is a good friend of mine, I had new valve guide seals installed at the same time, I took it in on Tuesday and picked it up late Thursday. Total cost for the 95 upgrade was less than $800.00 of course the cams were already done. I've got a new 2-N-1 V&H Pro Pipe coming and it should be here on Wednesday. We just got back from an over night ride to the southwest corner of our state 650 miles round trip, I now have 10,000 trouble free miles on the upgrade.
05 Fatboy
Sceam'n Eagle Ignition,
modified CV carb
SE Air Cleaner system
S&S 510 gear driven cams, If I was doing it all over I'd now go with the new SE cam plate and the same cams. Quieter operation of the cams, gear drive is noisy.
V&H Big Shots Staggered
95 Inch Upgrade
Average of 50 miles per gallon
Soon to have a V&H 2-N-1 Exhaust

Hey CB, isn't that T-Max only good on the later bikes with the exhaust sniffers????

This is the Issue I was talkin about
Maybe one of yer buddies has a copy.

thanks

It used the 02 sensors to auto tune the bikes,

I'd call TM to find out the details.

I know they are for the 2001 - 2012's.

Spend your money on head work. You'll get more bang for your buck. If thats not enough, then go with bigger cams. The timing chain upgrade is a good one, better adjusters, bigger oil pump, improved cam plate for better oil flow. All good things.
If that don't get you where you want thenput in the bigger pistons.
The local dealer had a test ride a few weekends ago. I wasn't that impressed with the bigger engines, 103 ci. They pulled a bit stronger than my 88 inch, not engough better to get me to trade in what I have. Not even enough to do the engine work to get the 103.
I think the 88 with the right work is plenty big enough.

Cam adjuster up grade is a must if something hasn't all ready been done to them. SO while doing that new cams are easy to add. Just like every thing else you will hear on bike talk, it's all opinions and what has worked for some one else.
Cams are the best Bang for your Buck. Just My Opinion.

Tough to compare a brokein engine to a New 103 engine that's still tight.
