Here we go again. Someone hears a few people say "you'll kill your engine with a low idle speed" and now they preach it to everyone else. If you don't let your bike idle for 15, 20 or 30 minutes at a time it doesn't make a ****. I guess that's why before fuel injection came out and most people had their bikes idling at around 5 to 600 rpm the engine would seize up if you let it idle for 5 minutes and all of the engines needed a rebuild after 1000 miles. Come on now. Good grief. The only major draw back to a very low idle is the load that is applied to the rod and crank bearings because of the slow revolutions.

I have a Fuelpak and there are no settings to "lower the idle."

If you remove the complete aircleaner assy and look in the lower right and corner of the throttlebody you will see a small hole in it. It may be filled with putty or some similar stuff. Behind it is the torx head adjustment. You can see it better if you look from the right side. It looks just like an old carb style idle adjustment screw against the throttle plate actuated by a spring. You have to take a long shaft torx and pass it through the hole in the corner and adjust it that way. At the bottom center of the throttle body you will see two holes side by side. They will probably be filled filled that putty like plug too. That is your airbleeders for each individual runner. All of those are set at the factory and plugged up so the owners don't mess with them. Hopefully they are set to correct specs.
If your bike is running fine, don't mess with them.

Well there you have it, it won't damage your engine. Just for for giggles and grins would the OP put a good oil pressure gauge on his engine, then record the oil pressure at 1000+/- 50 rpm, record it at the rpm he thinks the engine should idle at. You know just for fun.
