Can’t figure out why my engine is knocking and getting red hot on back jug
05 Softail Deluxe
Any help would be much appreciated, Thanks, Mikey

Sounds like it's got an oil restriction. Damage is probably already done. Pull it apart and inspect

I would've guessed lean condition in cylinder. Maybe head gasket or cracked head?... If timing was out both cylinders would be hot. No matter, if it's knocking pretty bad, you'll be tearing it down.

Red hot at 850-900, or red hot ideling at 1500 high idle?

The knock, well you need to be a lot more specific on that.

If it was something in the valve train, then it could cause your hot pipe.

EFI or Carb ? Model

My first guest for one cylinder running lean would be an intake manifold seal leaking.
With the rear pipe heating up I'd check over tightened exhaust push rod or valve seat not sealing.
Knocking just plain isn't good.
I'd start with a compression test.

For sure bagger, obviously start with the low hanging fruit

There is not enough information here, what if any modifications or work done done prior to post, 2005 should be EFI maybe not!

Do you have adjustable pushrods?

 

[Pebhvac]

Be nice to have more info. Does he know they're color coded? Was the oil tank removed? Sure sounds like the return and vent oil lines could be crossed.

Knocking occurred when the fuel in the cylinder ignites before it should
