My questions is, with one engines being considered revamped and a new design, are the issues that are talked about; lifter failure, excessive crank runout, marbles and ticking sound, excessive heat and all the other stuff that I've heard so much about in the last 7 years; are the 110 better now? This is MoCo's 8th year running with a 110 in their CVO motorcycles, you would think it would be a perfected piece of machinery by now.  I know time will tell and some of the engine builders and other engine enthusiast need to spend some time with these 2 designs to determine what's what.

I'm also sure there will be some technical bulletin released soon that gives more specifics about the changes but if anyone has information to prove or disprove the 2014 110 engines are better or more of the same, I would like to hear it.

Quote from information I gleaned from the 2014 CVO Limited:
"As part of Project RushMore for 2014, the CVO Limited has been redesigned from the ground up for more comfort, more power, better braking and handling and more classic style. The iconic batwing H-D fairing has been totally redesigned to reduce head buffeting. This bike is powered by a new Harley® High Output Twin Cam 110 Engine with Screamin’ Eagle badges. The new high-output Twin Cam 110 engine with Screamin' Eagle badges provides 110 cubic inches of power, a low cruising rpm, more low end torque, more passing power, along with silky smooth shifting of its 6-speed cruise drive transmission."

What's NEW about the TC 110" engine? Maybe they did a little tweaking, but it's certainly not new. All CVOs remain at 9.2:1 CR, while the twin-cooled" Limited and Tri Glide 103" engines are at 10:1 CR. They can do apparently do that with the water-cooled heads without it pinging (much?).

TQ is up a bit, but not much. Gearing is exactly the same as all of the other Touring bikes.

So what's NEW in the 110... other than the water cooled heads on the Limited? And why didn't they bump the CR along with the twin-cooled 103s?

Now, CANBUS IS new, and maybe that's where the extra jolt comes from... a better ECM that can control fuel and spark better.

I suspect they are still using the POS SE 255 cams in the CVOs, too. Probably shouldn't rev more than 4500 RPM with that water sloshing around the exhaust valve, anyway!

I stand corrected - the 110 engine in the CVO Deluxe, CVO Road King and CVO Breakout is the 110 that has been around from 2007 - 2013 (don't know if there are 2014 enhancements). This engine was not part of the Rushmore project. The CVO Limited was part of the Rushmore project and is considered the new 110.

However, I'm still interested in learning if the regular and NEW 110 engines have been improved over the 2007 - 2013 110 engines.

Well, they changed the lifters, I think, in 2013.  Whether they last longer? Time will tell, but people who know more than me about that stuff don't think it's JUST the lifter that is the problem.  Crank?  I SERIOUSLY doubt there is one smidgen of difference in 2014.  What incentive does HD have to put an improved crankshaft in the 110?  None.  Valve train noise is the combination of several parts, and again, I seriously doubt they changed anything.  But I could be wrong.

Heat management, with the water cooled head for the exhaust valve/port will likely be improved.

Until a parts manual comes out for the 2014 110's, nobody will really know for sure what, if any, changes have been made.  Other than the water cooling, of course.

[BryantH]

Your correct Midnight Rider - I'm trying to get my head around if there are improvements for the 110 and waiting for the technical bulletin or parts, would be best. I just fried my noddle a little more, remembered that the 110B in the CVO Deluxe and the Breakout is different. I just read that the 110A in the CVO Road King (not twin cooled) was in fact part of the Rushmore Project and is concidered a New engine because they revampted it - who knows what that means.


"The H-D CVO Road King model offers custom extended saddlebags that add to the bike's premium touring capabilities, and profile laced wheels with wide whitewall tires that add to its bold boulevard style. The new high-output Twin Cam 110 engine with Screamin' Eagle badges provides 110 cubic inches of power, a low cruising rpm, more low end torque, more passing power, along with silky smooth shifting of its 6-speed cruise drive transmission."

I've read through all the 2014 specs on the new Harleys, and there is only one model that I can find, the ultra limited that comes with the new twin cooled motor. The twin cooled must be in reference to being cooled by water and air. The cvo ultra and ultra classic make no mention of a twin cooled motor. I read about 3 models having the new motor, but the web site makes no mention of any others.

Limited, CVO Limited, and Tri Glide Ultra are all "twin-cooled".

...my 2012 FLTRXSE is "twin cooled"...oil and air, whats up with this stuff??

[JONNIEROCK]

          I just went back and looked, it make's mention of the rushmore project but it makes no mention of the twin cooled motor like on the limited, what i'm I missing.

It's in the Specs... "Twin-Cooled". But NOWHERE else that I could find, though...

Ken

[Midnight Rider]

Notice that NOWHERE does any of the literature mention the words "water cooled"...or I can't find any mention of it.  H2O is a dirty word to HD loyalists.

And THAT'S why I don't even ride in the RAIN, Terry!

          Found it. Thanks for the help.

Water cooled if you ride in the rain!

I noticed mention of a new cam and airbox for the 103's, supposedly producing more torque and hp at lower rpm's. I can't find mention of the cam change in the 110's. Still the 255?
