There's another utube ch that likes to tighten things "name" tight and runs the big flywheel nuts to 400ftlbs because there are riders that know the flywheels like to shift and he has the answer. I can't imagine the problems that might come from 400ftlbs of squish. Maybe instead remember that a 1950s-60s Ironhead isn't going to be a 2000's Hayabusa and make sure the engine is tuned to avoid detonation & preignition. The factory didn't publish torque specs to ruin your day or because they were stupid.
..That 'other' TH-cam guy....yeah, I'm pretty sure I know who he is.....seems to know what he's doing, but sure likes to 'throw' everything around instead of just laying it on the bench.... I've owned 3 1972 Sportys, and I've never even thought about those very thin crankpin nuts being tightened to over maybe 100 Ft. Pounds at the max...even the Harley Service Manual says 'Draw them up tight'....I'm pretty sure they're talking about maybe a 12" breaker bar at the max..no air powered tools....
When deciding to work on engines,knowing whether you have the skills is very important. If you don't,you need to reach out,you need to get a manual,you need to do your research. And you need to follow the RULES. Some people should never work on bikes. Anyone with a trade in butchering,stay away

Great investigation of a failure.
I see crazy stuff in my workplace daily. I need to retire.
Very good video.. I really like the analysis of what caused the failure. I think that is as important as the fix.
Yep, too much torque is often worse than not quite enough, the 3/4" impact gun has no business tightening critical fasteners.
That was an expensive over-torquing.
Yes it was
Nurbeled em up, lol, your vocabulary is so entertaining
🤘😎🤘
DONT THINK AN OLD BRIGGS WOULD HAVE RUN LIKE THAT
I've seen all manner of poorly assembled engines, and a Harley will run until it totally destroys itself.
That is a total disaster. Hard to imagine what happened

Read and get to know your manual.put it into practice.

I do not use a torque wrench on every thing, BUT, crankpin nuts, sprocket shaft nuts, pinion shaft nuts, head bolts. A torque wrench is mandatory.

Put the wrench down and step back away from the motorcycle. They walk among us.
