a 117" kit would definitely cure your issues.  Other option to consider is working with your current 110" and I would suggest the following

- Have the heads done.  This will allow you to replace the guides and springs that are of poor quality, while at the same time making the heads flow better.  For a good touring application, consider setting the compression at 10:1.  Won't be a hot rod, but a good reliable set -up.  Cam should be changed (discussed below)
- with the heads off, replace the pistong rings.  Likely your issue on oil consumption.  If you encounter issues with the cylinders, then consider boring out your current cylinders or moving up to a 117" kit.  If cylinders are good then a new set of rings will do the trick
- If you have not changed out the cam, then would highly suggest doing this with say a S&S 570 which works well with 10:1 compression as mentioned above.  Make sure you change the inner cam bearing with a quality unit.  S&S sells an install kit with bearing and gaskets.
- Definately change out your lifters.  A lot of failures noted on here.  S&S lifters are highly recommended, among others.  stay away from the HD lifters.
- While everything is open check your crank run-out.  Any more than 0.005" you should consider have your crank done
- Depending on mileage, consider pre-emptively changing out your compensator.  Not sure what version the 2010 CVOs used, but if it's the old non-screamin eagle version then i would definately change it out.

All great advice but I want to say that I would be more surprised to see run out under .005 then over. I have .00625 right from the factory. I plan on riding it. If I were to do gear driven cams that would change but I don't see the point otherwise. At 13k I switched lifters and cams and the cam plate, etc showed no wear.

The cams, lifters, heads, compensator, tensioner, pushrods, intake, exhaust and a turner have all been completed. With this much oil consumption the next step would be cylinders, rings and pistons. I was looking for some input to help make my next step. I had a few ideas about reducing the size of the engine to help with the fuel economy but I am not really sure what will work without major modifications. The 113 kit sounds very interesting. I am considering a 96 or a 103 replacement but would then need to re-paint either the engine or transmission.
 Just looking for options that are reasonable.

I guess I don't understand why you would want to go down in displacement. Many of us get 44-48mpg with higher compression engines? Not too mention I have seen plenty of issues with those motors as well. A coworker was heading to Sturgis last week with a friend that has a 14 SG with a stock 103. The engine blew up about 30 miles west of Sioux Falls. He lost 5 days while mother Harley fixed his "new" bike.  :nixweiss:

How about a S&S 124 crate motor?  I keep seeing good reports from people who have gone that way versus throwing a pile of money into the 110's.  Just a thought.

That is exactly what I did was the 124lc S&S swap ,very happy .I have a complete  110 I would sell

I did the 113, had the heads done, valves, 10.5-1 pistons, lifters, ss585 cams, and a tune on the tts for about 1/4 the cost of a 124. I absolutely love the way the bike runs now. It will scream once you get over 2800 rpm. Visually I have a stock granite 110 with original numbers.  May not be the setup you are looking for but it works for me. Where are you located?

I really like the idea of the 113 and keeping the stock look. This is the direction I am going to take. All I need is some direction as to which pistons and rings I should use. I am in South Carolina.

Boring the stock cylinders to 4.060 for 113 is a good combination, but due to ring fitment issues, I "backed into" a 117.

I would recommend some research to find a Builder with a good reputation (there are plenty on this site) that is familiar with the 113s to bore your cylinders and source / fit the pistons / rings. (one stop shopping)

My 117 / DD7 averages 39+ MPG 2-up / loaded on the Interstate at 80++. 35-37 around town or running the back roads.

I am no expert on the engine internals and had the work done in a shop. I can tell you he used the screaming eagle 113 10.5-1 forged pistons and rings. The bike has been as reliable as a new one should be and runs like a top. The shop I used was recommended by a member here but is in MS. Find a builder you trust and talk to him. Good Luck

3mcam, find a mechanic ( not a parts replacer) that really takes pride in his work. Believe it or not there are a lot of good mechanics that take pride in their work! That type of person will make sure your cylinders are round and that your rings fit properly. I had a 95 Heritage that used a quart every thousand miles. After my indy mechanic put in new pistons, rings, and bored the cylinders oil use was minimal. He told me he spent an extra 45 minutes making sure the rings were gapped just right.CAHDBIKER

My 110" CVO has finally gotten to the point where I feel I must make a decision. My troubles are excessive valve train noise/piston slap and unacceptable oil consumption. On my recent trip to Sturgis my 2010 SESG used 3.5 quarts of oil in a 4200 mile round trip and only obtained 30-32 mpg's.

I am considering several options. Rebuild the 110 with better parts. Upgrade to a 117 with top quality parts or to help with the MPG's  and valve train/ piston slap noise replace the motor with a 96 or 103.

I am requesting input or suggestions from those with more knowledge than myself. I have gotten over the need to have the BIG motor with tons of HP & Torque. Looking for reliability with MPG's.

My 06 Heritage with a 88" motor got 50-52 mpg's which I loved but was what I considered underpowered at least in my mind and my dreams of a BIG motor. Can an 88" be put in place of a 110" without major modification?

Sorry about your problems.  So many ways to go, but leave MPG out of the decision.  If you have a great running 113 or 117 and only get 30 MPG do you really care?  No one buys a 110 CVO for the MPG.  Good luck with your solution.

  You may find a big part of the poor mileage is the oil consumption contaminating the fuel mixture!
Harley will tell you that 1 qt in 1000miles is within their acceptable limits, but that just plain sucks.
May have been ok back in the flathead days, sure as hell not now!!
The oil consumption likely due to poorly fitted pistons/rings, wore out guides and seals or combinations of all of these. The 110's are kinda famous for it.
You could have a good reputable independent (lots here) rebore and fit new pistons/rings, install new manganese guides and Viton seals and be on your way!  fwiw  twinotter

21k on my 110 and it never uses a drop in between oil changes  :nixweiss:

I don't think going down in the engine size will decrease your fuel consumption, I have a 127" with 10:1 compression and a 640 lift cam, 268 duration this is an evo motor but I get better fuel economy than my brother inlaws stock 2008 96" this was on a 10,000 mile trip my sisters stock 2008 deuce was about the same, get your engine running right, bump up the compression junk the factory tune and your mileage will improve
