The interest is not because my engine has any problems..  My 110 is running strong, no problems, throttle body noise is quite evident in lower RPMs and the fairing on the 2011 CVO SG channels that noise up to you...  7640 since December, running strong.   I have no problems nor have heard of any on the newer 110 c.i. engines here. 
Now, since I got the idea to put a 120R motor in an Ultra, I have been keeping an ear to the ground.  I have heard one running in a SG, and heard of two, and the Owners are raving about them.  One done up has Dynoed about 120 and 120, and everyone is saying only good things about them.

I have a new Big Blue 2011.5 on the water, coming next month, and am thinking about putting the 120R motor in it.  I want to run in the 110 to at least the first Service, to check it out for Warranty before I mothball it.  Coolest glass topped coffee table base on earth...    Anyway, run in, no problems, I can keep it to back up the 120R or sell it if the 120R motor is still strong.  Anyone know of any problems or top mileage on any 120R motors running in America?   They idea is to have one Hot HD, to put any "Granny Glide" comments right to bed... heh he...   

Only good reports here, but they are just 12 months old since the release..... It would be cool to have a two litre Dresser here, and blow off the GoldWing sorts... heh he....

[CVOThunder]

  Been thinking along the same lines myself.

[ALRG8TOR]

Thinking of joining the "dragger bagger" set, eh? If you do let us know how it works out. 

[CVOThunder]

It'd be cool but probably not in my new one. Thinking along the lines of a draggin Road Glide but it'll be after I finish working overseas in a yr or 2. Maybe run the Baker DD7...not sure but I'm reading about it now.

[Big Dog]

I believe the 120SER has only a 90 day warranty on it, correct me if I'm wrong on that. I wouldn't get rid of my 110 just in case.

[Hotrod50]

From what I've heard the 120R isn't very streetable.  You would probably need to re-cam it and re-tune it.

[Steve Cole]

I own a 120R and have tuned a few of them. For starters there is NO warranty on the motor, It's a race engine. They are streetable enough in a FLH to take a trip without issues. Customer that is doing testing for us just put 3000 miles on it loaded for a week long trip, CA, OR, WA ID and back all with no issues anywhere on the trip. Weather was cold and raining to 100+ temps and rode from sea level to 6000" and snow on the ground. Bike was loaded with everything he needed for a week long trip and camping gear as they camped out each night. Average mileage on the trip was 44 with a high of 47 and a low of 38. He said the 38 was when he was running it hard and playing around a lot. 47 mpg was when cruising on the open highway or climbing the mountain as long as he did not race around, keeping speeds to 55 - 75mph. While were not done yet with testing it's looking good so far.

Hello Guys,
And yes it is very street able, and three running here have their Owners raving over them...  My thinking was to break in my 110 to make sure it is all OK and then keep it as a back up.  Here in Oz, you catch a little crap from the Clubs, calling the Ultra a "Granny Glide"... It would be cool to come up alongside and lift the front wheel on a gear change as you leave them.. heh he.. 

Anyway, so far so good, no fairlures or problems.  However, only out since July 2010, myself I drive only about 15,000 kms a year, which is about average I think.  They have not been out long enough to know how well they last, but if you are not screaming them on a drag strip at 5000 + rpm all the time, I cannot see why they would not be as good as the rest ....

Anyway, no problems here in Oz on late model 110 c.i. or the new 120 R motors so far.
Come on down, the beer is on me...

what about the fly wheels, have they been welded now? so they won't get knocked outta balance

[CVOThunder]

Slight hijack. I was thinking about what's involved with truing up the wheels and welding them up but didn't these all used to be bolted together back in the day? I never pulled the lower ends apart on my shovelheads but I thought sure they were bolted together. When I get finished here I wanna take some time and go to bike school. VA should cover it but we'll see. Would be great to enjoy something for either side work or just another hobby. Heck I can paint, do wiring, decent with a welder and have rebuilt enough car engines that I should enjoy wrenchin on bikes. Sorry to drift away on yer thread.

Oh, but I do like my Holden Monaro/GTO. I know there's a Ford/GM hatred thing going on there but hey I've had good luck with my GM's. So far I've visited Freo, Perth and Hobart (thanks to the USN) but family came from Sydney back in the 1850's. G'day mates!

Not welded, just pressed together like they have been. It's said they change the way they press fit them but I do not know about that one. I took mine apart new as I felt it was the right thing to do. I've checked the crank and it was fine, then plugged and welded it to make sure it's not moving. In the process of fitting it for timken bearing and modifying the case for them. Will reassemble the engine after that with the cam as is but I will be setting the quench area as needed during reassemble. I'm glad I pulled mine apart as there is lots of little things I found that made it worth it for me. I want to put it in and forget it, not work on it afterwards!

Steve - would you mind sharing what you found & yr/model .... thanks

[Half_Crazy]

You did the right thing. If you're gonna spend the money for horsepower, you might as well spend a little more as insurance that it's reliable horsepower.

[johnsachs]

The several I've been involved with had pistons at "0" deck. Can't get better than that.    Realize, base gaskets are direction specific. Some are marked..some aren't.

[Cowboy2]

I would like to know this proceedure for the plug welding and machining for the Timken bearing on the flywheels....

But I would REALLY like to know about a precision balancing, as that would seem to be very important if you are going that far into the lower end...
