Nice report, or better said, another boring, HoHum, UOA on the rock bullet proof Harley Twin Cam engine.
I would expect your numbers to be slightly higher due to the higher output of the engine and mods that you have, not anymore different then any engine with mods.
Copper - not an issue or even a thought, every twin cam has higher copper in a new engine.
I love my 103 HO Twin Cam, its been rock solid, repair free for 5 years and 26,000 miles now, I will not even consider the M8 until has the same reputation as the Twin Cam, so far it seems HD has a long way to go on that one.
Im still air cooled and staying that way, HD has missed the mark on the reliability of liquid cooled engines in one of the worst ways.
