Low Idle
On the Older (2006 and older) the idele was set above 1000, because of oiling.
The newer oil pumps (after 2006) have 30% more volume and 60% more scavenging
(according to HD ) right??
So, couldn't we actually lower the idle a couple 100RPMs on the newer models and still be safe???

there are many parts of this equation, remember that our motors do not have much of a flywheel to store forward momentum. flywheels are lightened to allow for quicker acceleration

My 99 Ultra has 99,860 miles on it & idles around 600rpms. Has for over the past 50,000 miles & not sure beyond that. Even when I try to set it up around 1000 it will lower the idle on it;s own to the 600 mark. Seems to be cooler in the summer (from the times I did have it set to around 900-1000) , sounds better & oil pressure does not get that low to worry about. Good luck
