You got it -- if we drop our idle speed too low then we die the death of 10,000 little scrubs. Too many did this while learning about the idle speed trick (some just liked the loping sound of a very low idle speed).
Suzuki recommends a 1,000 to 1,100 rpm idle speed, but after a cam event like Lancer just had he will require a slightly higher idle speed as his head will leak more oil out the enlarged bearing gaps.
Verslagen is correct, we have flow and pressure issues out of our oil pump at low rpms.
Our oiling system is a minimal system, it has no over pressure regulation at all so it was designed to pump at max rpm a designed flow that could exit the system through the existing passages. It can pump
too little at idle and
too much at max rpms.
Take me for example, I am a wicker with a stage 2 cam. I run me some high RPMs and I suffer from extreme oil pressure making the side cover oil gallery at the top of the case difficult to keep pressure sealed and leak free. So you see we can have issues at both ends of things because of the oiling system the bike comes with.
============
The stage 2 cam from Web Cam has had the steel cam journals dressed down a bit to slightly below the Suzuki factory diameter specs so I have "increased journal clearances" for that reason. I need to run a sightly increased idle speed to make sure I keep good oiling going on when sitting at a stop light.
============
Lancer will also possibly have some additional issues setting his valve clearances as the extra gap he now has is an appreciable percentage of his intake valve clearance number.
"Durn, I set it and it was right, I come around again to check it and it's way too (tight
loose)."
(you pick what happens this cam rotation turn around)
