I just did an oil change on my '06.
And switched to royal purple (transfer and crank).
The bike no longer has a "High idle" when 1st started...
It starts at 850rpms, and stays there (it started at 1100rpms before, and low idle was at 950)...
By the way...
Before the oil change, my bike would have a "fast idle" upon starting, of 1100RPMS.
I find the fact that my "fast idle" is completely gone enough to make me think that at the very least "dino" oils suck...
And that Royal Purple is some pretty good sh*t...
But, I haven't tried a different synthetic oil as of yet.
So, who knows?...
Hmmm...I'm throwing the B.S. flag on your theory....There is a system in the bike designed to raise the idle when the engine is cold. Simply changing to a different type of oil would have nothing to do with that.
BTW, I would recommend 950 being the lowest idle. The oil pressure drops off quickly below 900. It's amazing what you notice when you have a gauge. Like the 10 PSI of oil pressure I was seeing at idle today when I was stuck in july 4th crawling/stop and go traffic for about 45 minutes....I cranked the idle up just a tad to be closer to 1000. Even mobil 1 thins out when you sit in florida traffic in july....I'm thinking of getting a cooler.
