[11 CVO Convertible]

I purchased a used 2011 CVO Softail Convertible with 1,600 miles on it in October of 2012.  I was expecting a lot more from the CVO's, so I was very disappointed in the performance.  I put another 1,200 miles on the bike before getting fed up and tearing the motor apart.  I'm keeping the stock bottom end and cylinders on this build as I'm only hoping to get one or two years out of it.  My goal is 130/130+.  Here is plan:

-Stock bottom end
-Stock cylinders
-Compression set at 11.0:1
     -SE 10.5:1 pistons
          -Swain Tech Gold Coat on pistons
     -Cometic .027" headgaskets
-Hillside Stage III CVO heads w/ 2.120" valves
     -Mill and set combustion chambers at 94cc's
     -Swain Tech thermal barrier coatings on combustion chamber, valve faces, and exhaust ports
     -Swain Tech flow coat on intake port
     -Swain Tech PPM low friction coating on valve stems
     -Woods 188 valve springs, retainers, keepers
-Woods TW-9F-6 cams
-Woods lifters
-Zippers tensioners
-S&S pushrods
-S&S roller rocker arms
-S&S 58mm Throttle Hog throttle body
-AIM lockup clutch w/ Barnett spring
-Bud's oil cooler
-TTS Master Tune (will be tuned Ed at The Dyno Difference)
-RB Racing Pro Stock Spyder exhaust w/ 2" Primaries


The bike is tore down all parts are in the mail to get reworked.  I'm just sharing my build and progression for those that would like to see the results.


Here is the disassemble:

Could you measure the dome on that piston for me? Need to know in .ooo not in cc,,thanks

sounds like a nice build ...ques tho   the 1  to  2 years  ?  plan  what are you doing afterwards  ?

[prodrag1320]

why not just go 124" now and be done with it??

[HD Street Performance]

Sure, you betcha or a HD 120r kit and your case and heads. Actually the 110 barrels will bore to 4.060 and that would save a case bore and barrels. Suburban HD in Wisconsin does this all the time and sells a 113" stock stroke piston at 4.060".  Buy a crank and pistons and go to 120". If the extra 4" are wanted then bore the cases and use an S&S kit. The side benefit of the 120 or 124" are flat top pistons become viable with later closing cams.

We've bored those to 113" on about 1/2 dozen different occasions, as well.

There is an advantage to the S&S or HD Bigger bore cylinders however, the longer spigot for support and piston stability.

[HILLSIDECYCLE.COM]

One example is that we had a local client come in 2 weeks before Sturgis last summer, with a lifter and cams that created a debris-field in the cam chest, harming the pump/plate, etc,(local dealership said the noise was "normal" for those!!) and the crank was fubared as well.
Even with the crank going to Darkhorse, he went to Sturgis on time, with his now, 113"er, and logged over 8,000 miles on it prior to putting it up for the winter, last fall.
Like Phil Robertson says, he is "Happy, Happy, Happy".

  Have you told Ed about the plan ?

  Sounds like a Noisey PMS build and I would almost bet he would agree

What?

Looks real nice

I will when I get them back.  I had to order a new deck bridge for my dial indicator.  I couldn't accurately measure down to the thousandth, but I got close.  For some reason, the rear piston was about .003-.004 lower that the front.

124" build assuming I still want to keep the bike.  I plan to buy a Street Glide in the next year or two, so these parts will go on the SG and I'll do a 150/150+ monster that runs on E85.

why not just go 124" now and be done with it??

I don't have all my tools.  I started a new job last summer, and I sold my house and put all my tools in storage.  Once I get a new house bought and get a shop/garage, I'll tackle the full build.  I also didn't want to have to go chain drive yet.  I didn't want to loose the rear belt sprocket that matches the rim.  Once I get my stuff out of storage, I plan use my CNC mill to modify the rear belt sprocket to accept a bolt on chain sprocket.

  Have you told Ed about the plan ?

I spoke with him Friday about it.  He made no mention on any potential issues other than making sure I had my squish set at .030-.035 and getting some matched Marren 5.3 injectors.

Looks real nice

Thanks!

Just to be clear, I just need to know the height of the piston dome from the flat part of piston to top of dome, not the deck height.
Just cant remember what mine were, and no one has one I can measure, thanks a bunch if you can do that for me.

.175" from quench area on piston to top of thr pop up.

[chicoman]

Thanks so much for checking that for me. That will change my cam decision.
