Lower revs when idle

Lower revs when idle
Got a Fuelpak 3 and it lets me lower revs on my bike. I've heard some old bikes rev on idle real low and sounds real nice. Does this damage the engine in any way? Does it cause it to over heat? Or does it improve engine life and lower engine wear? Haven't tried it yet. Fp3 support doesn't go into details on all the features and there's no catalogue or instructions on hoy to program the bike for different things, so here I am. Asking the real pro's, the guys that ride and have learned through experience. 👍

With that said, I have the Powervision and my idle is set at 925 rpms with no issues for last 3 years.

If your engine is spinning slower it will not rotate the oil pump as fast. Baisley spring or Axtell setup comes especially handy here (good upgrade to do along with cam/engine build).

"Oil pressure" doesn't have much to do with proper lubrication of ball and roller bearings, like it does with plain bearings (bushings).
Take your wheel bearings, for example. Virtually no oil pressure.
I've read tons of posts here warning about the dangers of low oil pressures at low idle speeds, but haven't yet seen anything solid to back it up.

Ok, I get what everyone is saying.
I do like my engine, it's a 96" V-Twin that pushes my Dyna hard enough with no leaks and reliability.
Carb doesn't have oil pressure problems at low rev?
I did notice on the Fuelpak that as engine heats up, it is set to lower revs. guess it lowers head temp. Right? Wrong?
Also, I noticed on a road trip, through some mountain area, that when I slowed down on the top with a bit cold weather, my revs went down really low. Can't recall if it was mid 800's, but it did a galloping horse sound. Real nice.

The Oil pressure problem is more of a urban myth i guess you call it. In 2006 they made carbed and EFI bikes and your right oil was not a so called problem with a carb. Here is the real story. The EFI bikes need to idle higher so they can keep up the charge in the electrical system. They Fuel pump and ECU pull to much current so the alternator has to keep every one happy at idle. If you drop to low the alterntor wont keep up wth the battery is all if you dont let the bike sit in traffic etc etc and idle long nothing will happen at 800 rpm
