I did about 250 mile ride with some buddies, then I headed home 120 miles. I made it about 20 miles and the engine quit, I looked in my rear view mirror and I have never seen so much smoke in my life, and I have had a couple of car engine blow. After waiting 3 hours for a tow truck took it to my dealer. They ran compression check, both cylinders read 10 psi. So it was decided I am gonna need a rebuild. Instead of a rebuild I had them order a crate engine 120st. This engine should put a little more umph in the trike. Harley did not back order the engine so I am hoping it arrives soon. So then install and Dyno. Want it back as the weather up here has finally gotten nice for riding and the wife and I have some trips planned. So that is what I did to my bike, I blew the engine
. I surely thought I would get a lot more than 60,000 miles out of an engine. Of course the extended warranty expired last summer.

Really sorry to hear that. You will like the new 120.
I know it is no consolation, but you went longer than many. The "normal" amount of heat in the 103's cause accelerated wear and tear. My 2011 had to be rebuilt under warranty at 10K miles.
I know of dozens that have had to be rebuilt at 10-30K miles. All because of the heat causing accelerated wear.
The same thing will occur with the 120, but the good news for any of the engines, 103, 107, 114, 120, is that there are some basic things you can do to get the heat down and have well over 100k trouble free miles.
You can see the REPORT HERE on how to cool down a Twin Cam & M8 engine.
I took the steps listed in the report above on my rebuilt engine and had over 50k trouble free, full power miles before I sold it.
I also took the same steps on my 2014 Twin Cam and am approaching 50K trouble free, full power miles on it.
