I would guess he calls them junk because of the problems he has run into while working on them. The motor is no better than your 110 motors, and warranty takes forever. To keep warranty you must inspect and or change your lifters every 5k. The crank assy is just like the one in your motors now. The only thing you are getting is a larger displacement. If you go back and read all of the problems with the CVO motors that will answer your question. If you really want a 120 inch motor call the guys over in Elkridge Maryland. They do build a good one from the ground up!!!!
Like I said in my above post I would rebuild your motor from the ground up using your factory cases using S&S and Axtel parts. And if you think that the 120 motor is a bargin go ahead and buy one. But when you have a problem with it, you have been warned!!!!!

THE DAWG
So Dawg is this like,

, your the official Axil spokes person or what?
That's cool but you also didn't answer the question asked of him.
To keep warranty you must inspect and or change your lifters every 5k.
Jim's is a viable option for many members here, are you saying that Jim's requires lifters to be inspected or changed every 5K?
Is that in their sales brochure or warranty information?
People that plan to spend 5, 6, 7K dollars or more want facts about an item they are investing in.
But when you have a problem with it, you have been warned!!!!!
Facts man, that's why the original question was asked.
Facts will help everyone here to learn.
Drama may increase post count but unless facts are told, drama means nothing.
The motor is no better than your 110 motors
Yes I have had issues from my 09 110 but after 39K miles in 20 months I bet I have spent less on my 110 motor than you have on your 103.
Inquiring minds want to know.
