JUST for conversation here.
Bike is 09 FLHR 96" with full stage one intake and exhaust usiing a Gen4 fuler be Dobeck and SE255 cams. All else is stock
Just turned 51,000 miles on the King.
I just got off a 5 day ride of two up and loaded down. Up in the hills of Az. Mostly on back roads and hard pulls up.
My oil temp, I have no way to check on this ride. BUT, The temps were in the 95* and not lower than 85* at best.
My 20/50 Redline oil showed "Not too Hot" as the Oil Pressure was running at 40+ lbs at normal cruise and while pulling hills. Never below 10/12 lbs at idle.
( pressure on my un-calberated HD valve cover mounted gauge):s
I do use a Jagg 6 row side mount cooler off the left side of down tubes...
A Jagg Thermostatic control mounted in front of the oil filter and hosed under and up to the cooler. Neat installation.
Before the cooler, On a really hot ride, just like the one I was on, the oil pressure woud stay around the 30-32 mark and would idle down close to 5/10 lbs. Same cam plate and oil pump used,,, difference being the 6 row thermo cooler.
