Blown Head Gasket
As I sit here 3 miles from home waiting on a tow....
Stopped at a stop light to make a left turn. As I went through the intersection, I heard a pop and then what sounded like a hole in the tire as it went round and round. I looked for the best place to pull over and started that way. Thank you for a down hill as my bike died and I coasted to a safe place.
As I investigated, I feel air escape between the rear head and jug just by the the header as I crank it over. Have code p1 003 system relay contacts open efi
Guess things could be worse and it happen in the middle of nowhere.
Get it home and call Harley in the morning to come get it. It's a 2013 so I have factory warranty.

Got the bike home. Cyclone and HOG did a great job with fast turn times...
Upon more investigations, I have discovered that the fuel pump is not cycling on. Pulled and checked all the fuses with a DMM and they are good. (ETA - Actually, I double checked and found the ECM fuse blown. Must have skipped that one the first time around)
I know that I have air coming from the rear cylinder just above the exhaust port. You can hear each compression stroke. Where does the air from the compression releases go?

Thanks guys. I will correct my error..... I must have skipped a fuse when checking. Double checked them all again and found the ECM fuse blown. Replaced it and fuel pump cycles now but still have the air escaping from above the exhaust port. That's strange the fuse tripped as the bike ran for about 15-30 seconds after the noise started. Oh well, I'm done looking at it. Guess I'll find out what Harley has to say.

I remember years ago with an old truck I had, I blew a head gasket and after it happened again, I discovered that an exhaust valve lifter was clogged and would not pump up.
I've read about the crappy design of the lifters on the TC, could this have been the cause? Maybe a lifter that bled down and was not pumped up, leaving an exhaust valve not opening fully?
Just trying to figure out what would cause this.

"Air" escaping from over the exhaust port would not be a head gasket. Possibly, but not likely, there could be a loose ACR. Or the header pipe is not sealing against the port.

Yes, you would be correct, not a head gasket as I originally said.
