I had a gut feeling that 1.5 turns out from a finger tight setting was much too loose, but whereas I broke it in by the book and maintained it myself by the book and was worried about warranty, I stayed with the 1.5 out per book.
If one follows the break in procedure and then the first chaincase inspection A(by the book), the sled has not seen much in chain stretching yet. Once broke in and lots of WOT short or long runs, the chain does stretch quickly.
I did have the dealer look at it while he had my sled, and yes 1 turn out should be the sweet spot.
The book should be updated to reflect that. Looks like I now have a stock looking color to my oil so I shall stay with what they installed until my next chain case inspection, then I will go back to the same type 75 - 90 Syn, I think.
Shall research the stock Yamaha chain case oil also. It looks impregnated through site glass, maybe graphite?
