Default motor seized....

Known bike specs,
1971 FX Super Glide numbers on the case and frame
FLH appearance
motor mods unknown, friend says it sounds as if it has a "G cam", super E carb, Sturgis Dual belt drive, I rebuilt oil pump, replaced oil pressure switch, Changed oil, blew out oil lines, new ignition system (blue streak points and condensor) Accel super coil and big wires. re built carb. Low miles but i don't trust the OD.


I was on my way to work Saturday evening. This was the bikes first highway run at a maintained 65-70 mph. I wanted to take advantage of the super light traffic due to shutdowns and see if my "Shovel head Sneeze" was going to show up once i leveled out the throttle for more than 1/4 mile. The ride was satisfactory until the exit for work when i heard the noise that i have heard before. It is a weird metal squeaking no oil type noise with some knocking that increases in volume right before it shuts down. It has happened before about a year ago it happened twice right after i got the bike running.

I was cruising so I pulled in the clutch and it shut down. Seeing that i was still merging off the highway I popped the clutch out while drifting about 55 mph and she lit right off. So down one and off to safety i went. It was a struggle to keep it going at the light she died going up the hill at the next light. It was a quick stop also not a stall. I pushed it off the road onto the sidewalk. It wouldn't crank with the starter it tried but would just make that labored noise like it was trying to move but couldn't. In the past when this happened it fired right back up. So i decided to try and kick it. Nope Locked solid. So now what to do. I tinkered and looked for a few minutes bike didn't seem hot. Oil was barley warm. Now i was gonna be late so now or never I just gave it a big ole kick it freed up so i hit the starter it came to life not very well but was alive. I ran down around the corner to work and shut it off. Punched in and then went to move it around back. It wouldn't start just a big backfire after about 4-5 big revolutions. Frustrated i walked away. I then went out about an hour later after securing a trailer and ride home from a friend to move it around to the back side of work out of the way. I was able to start it but it didn't want to run seemed out of time. I checked my plate and points all were tight and still sitting where i marked them last. (Second ride since i put new coil, points, plugs wires etc on it) went out at lunch to mess with it a little and it doesn't want to start it seems to be out of time. Extremely frustrated and aggravated with life at the moment because of the bike and the fact we received reduced hour lay offs earlier in the evening i just shoved it on the trailer and now it sits in my garage.

In the past when this happened i thought maybe the clutch was dragging or hanging up so I wasted two cans of brake cleaner and adjusted the clutch, problem went away. But thinking back I also re-timed the bike, statically on the TDC mark. Could it be seizing up and slip[ping on the crank causing it to lose time? Could it just be because I have not fully timed it due to a lack of knowledge and tools to do the advanced timing. I am going out this evening to put the bike up on the stand and begin to explore and poke stuff with my screwdriver. I was hoping that maybe I could get some insight and help to fast forward my random looking around for an issue. I never did a full disassemble of the bike when i got it because i wanted to try and find all the problems and only tear it apart once. I am new to shovel heads and new to Harley, but i am not new to using a wrench.

Thanks in advance and I am a night shift guy so my hours are weird plus there is a lot going on for everyone now so for those of you that chime in for help please stick around and excuse late or odd hour replies.
