I knew I heard it about 50 sec in.
I respect Keith but unless he's using .0035" on the mains, I'd use nothing heavier than 15W-40. And preferably 10W-30. I did at .003". Today most guys use .002-.0025".
Regardless-run the ass off it and in 1K miles it will be telling you what it likes.
Don't obsess after every ride.
